Oceanhawk Acquisition Corp.

515 Madison Avenue, 8th Floor

New York, NY 10022

United States of America

Dear Sirs and Mesdames

**Oceanhawk Acquisition Corp. (the "Company")**

1. **Background**

We have acted as counsel as to Cayman Islands law to the Company in connection with the Company's registration statement on Form S-1, including all amendments or supplements thereto, filed with the United States Securities and Exchange Commission (the "**Commission**") under the United States Securities Act of 1933, as amended (the "**Act**") (including its exhibits, the "**Registration Statement**") for the purposes of, registering with the Commission under the Act, the offering and sale to the public of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) 1,000,000 units (or up to 1,150,000 units, if the underwriters option to purchase additional units is exercised in full, which the several underwriters for whom The Benchmark Company, LLC is acting as representative (the "**Representative** "), will have a 45-day option to purchase from the Company to cover over-allotments, if any) ()"**Units**") at an offering price of US$10.00 per Unit, each Unit consisting of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) one Class A ordinary share of a par value of US$0.0001 of the Company ("**Class A Ordinary Shares**"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) one-fourth (1/4) of one right to receive one Class A Ordinary Share upon the consummation of an initial business combination ("**Rights**");

"Carey Olsen" in the Cayman Islands is the business name of Carey Olsen Cayman Limited, a body corporate recognised under the Legal Practitioners (Incorporated Practice) Regulations (as revised). The use of the title "Partner" is merely to denote seniority. Services are provided on the basis of our current terms of business, which can be viewed at: http://www.careyolsen.com/terms-business. CO Services Cayman Limited is regulated by the Cayman Islands Monetary Authority as the holder of a corporate services licence (No. 624643) under the Companies Management Act (as revised).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) all Class A Ordinary Shares and Rights issued as part of the Units; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) all Class A Ordinary Shares that may be issued upon exercise of the Rights included in the Units.

This opinion letter is given in accordance with the terms of the Legal Matters section of the Registration Statement.

Capitalised terms used in this Opinion shall have the meanings ascribed to them in this Opinion and/or the Schedules.

2. **Scope of Opinion**

This Opinion is given only on the laws of the Cayman Islands in force at the date hereof and is based solely on matters of fact known to us at the date hereof. We have not investigated the laws or regulations of any jurisdiction other than the Cayman Islands (collectively, "**Foreign Laws**"). We express no opinion as to matters of fact or, unless expressly stated otherwise, the veracity of any representations or warranties given in or in connection with any of the documents set out in Schedule 1. The Resolutions are the only corporate authorities related to the offering passed on or before the date of this Opinion.

3. **Documents Reviewed and Enquiries Made**

In giving this Opinion we have reviewed originals, copies, conformed copies, certified copies or notarised copies of the documents set out in Schedule 1.

4. **Assumptions and Qualifications**

This Opinion is given on the basis that the assumptions set out in Schedule 2 (which we have not independently investigated or verified) are true, complete and accurate in all respects. In addition, this Opinion is subject to the qualifications set out in Schedule 3.

![](ex5-1img4.jpg)

5. **Opinions**

We are of the opinion that:

5.1 **Due incorporation, existence and status** 

The Company has been duly incorporated as an exempted company with limited liability under the Companies Act (as revised) of the Cayman Islands (the "**Companies Act**"), is validly existing and was, at the date of the Certificate of Good Standing, in good standing with the Registrar.

5.2 **Issuance of Securities** 

The Class A Ordinary Shares (including the Class A Ordinary Shares issuable upon exercise of the Rights in accordance with the Rights Documents) to be offered and issued by the Company as contemplated by the Registration Statement have been duly authorised for issue, and when issued by the Company against payment in full of the consideration as set out in the Registration Statement and in accordance with the terms set out in the Registration Statement (including the issuance of Class A Ordinary Shares upon the exercise of the Rights in accordance with the Rights Documents), such Class A Ordinary Shares will be validly issued, fully paid and non-assessable. As a matter of Cayman Islands law, a share is only issued when it has been entered in the register of members (shareholders).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3 **Legal validity** 

The execution and delivery of the Unit Certificate and the Rights Documents, and the performance by the Company of its obligations thereunder, have been authorised by the Company and, once the Unit Certificate and the Rights Documents have been executed and unconditionally delivered by any director or officer of the Company, the Unit Certificate and the Rights Documents will have been executed and delivered on behalf of the Company and will constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms.

6. **Reliance**

Except as specifically referred to in this Opinion we have not examined, and give no opinion on, any contracts, instruments or other documents (whether or not referred to in, or contemplated by, the Documents). We do not give any opinion on the commercial merits of any transaction contemplated or entered into under or pursuant to the Documents.

![](ex5-1img4.jpg)

This Opinion (and any obligations arising out of or in connection with it) is given on the basis that it shall be governed by and construed in accordance with the laws of the Cayman Islands. By relying on the opinions set out in this Opinion the addressee(s) hereby irrevocably agree(s) that the courts of the Cayman Islands are to have exclusive jurisdiction to settle any disputes which may arise in connection with this Opinion. We assume no responsibility to advise any person entitled to rely on this Opinion, or to undertake any investigations, as to any change in Cayman Islands law (or its application) or factual matters arising after the date of this Opinion, which might affect the opinions set out herein.

This Opinion is addressed to, and is solely for the benefit of, the addressee(s), their counsel and the purchasers of Units pursuant to the Registration Statement, and may not be relied upon by any other person without our prior written consent; provided that, in connection therewith, we hereby consent to the filing of this Opinion as an exhibit to the Registration Statements and to the reference to our firm under the headings "Legal Matters", "Risk Factors", "Description of Securities—Certain Differences in Corporate Law" in the prospectus included in the Registration Statement. In giving this consent we do not admit that we are in the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder.

Yours faithfully

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. A certificate of good standing relating to the Company issued by the Registrar of Companies of the Cayman Islands (the "**Registrar**") dated 20 May 2026 (the "**Certificate of Good Standing** ").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The unanimous written resolutions of the directors of the Company (the "**Directors**") passed on 19 March 2026 (the "**Resolutions** ").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. A draft of each of the following documents (the "**Documents** "):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the form unit certificate representing the Units (the "**Unit Certificate** ");

**B. Scope**

![](ex5-1img4.jpg)

**SCHEDULE 2**

**ASSUMPTIONS**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The full power (including both capacity and authority), legal right and good standing of each of the parties to the Documents (other than the Company under the laws of the Cayman Islands) to execute, date, unconditionally deliver and perform their obligations under, and their due authorisation, execution, dating and unconditional delivery of, the Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Each Document constitutes legal, valid and binding obligations, enforceable in accordance with their terms, of each party to that Document under all laws other than, in the case of the Company, the laws of the Cayman Islands.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. All authorisations, consents, filings, registrations or other requirements of governmental, judicial or public bodies and authorities required under any law (including the laws of the Cayman Islands) for any party (other than under the laws of the Cayman Islands, the Company) to execute, or deliver, or enforce any Document or perform any of its obligations under any Document have been obtained, remain valid and subsisting and have been complied with.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The choice of governing law in each of the Documents has been freely made in good faith (for example not made with any intention of avoiding provisions of the law with which the transactions under the Documents have the closest and most real connection) and, where such law is a Foreign Law, would be regarded as a valid and binding selection, which will be upheld by the courts of such jurisdiction as a matter of such governing law and all other laws (other than the laws of the Cayman Islands). There is no reason for avoiding that choice of governing law on grounds of public policy or otherwise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. No invitation, whether directly or indirectly, has been made to the public in the Cayman Islands to subscribe for the Units, the Rights or the Class A Ordinary Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. None of the Proceeds of Crime Act (as revised) of the Cayman Islands relating to money laundering, the Misuse of Drugs Act (as revised) of the Cayman Islands relating to drug trafficking or the Terrorism Act (as revised) of the Cayman Islands relating to the financing of terrorism is relevant to the transactions contemplated by the Documents or to any payment made or to be made thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. None of the parties to the Documents are acting, or will act in a matter inconsistent with United Nations or United Kingdom sanctions as implemented under the laws of the Cayman Islands or extended to the Cayman Islands by the Orders of His Majesty in Council.

![](ex5-1img4.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. All necessary consents have been given, actions taken (other than those required pursuant to the laws of the Cayman Islands) and conditions met or validly waived pursuant to the Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. The Company has entered into the Documents in good faith for *bona fide* commercial reasons and on arm's length terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. The conformity to the original documents of all copy documents supplied to us (whether in hard or soft copy format).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. The authenticity, accuracy and completeness of all documents supplied to us, whether as originals or copies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. The genuineness of all signatures, stamps, initials, seals, dates and markings on documents submitted to us.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. No Document has been amended, modified, supplemented, revoked, rescinded or terminated since the time of its execution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. There is no document or other information or matter that has not been provided or disclosed to us, which could affect the accuracy of this Opinion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. The Company has entered into the Documents as principal for its own account and not as agent or fiduciary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. No Foreign Law qualifies or affects this Opinion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17. Words and phrases used in any documents that we have reviewed that are not governed by Cayman Islands law have the same meanings and effect as they would have if those documents were governed by Cayman Islands law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18. The Articles will be the memorandum and articles of association of the Company in effect at the time of the issue of the Class A Ordinary Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19. The Resolutions will be the only corporate authorities related to the offering passed on or before the issue of the Class A Ordinary Shares.

![](ex5-1img4.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;20. The power and authority of the Company and the Directors have not been restricted in any way other than as set out in the Documents, memorandum and articles of association of the Company or as arising under Cayman Islands law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;21. The Directors at the date hereof are, and at the date of the Resolutions were, as set forth in the register of directors and officers of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;22. There is no contractual or other obligation, prohibition or restriction (other than arising by operation of the laws of the Cayman Islands or as set out in the memorandum and articles of association of the Company) which may limit the Company's ability to enter into or perform its obligations under the Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;23. There is nothing in the corporate records or minute book of the Company (which we have not inspected) which would affect this Opinion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;24. Prior to, and immediately following the execution of the Documents, each of the parties thereto was solvent (both on a "going concern" and "balance sheet" basis) and did not enter into the Documents with the intent to defraud any creditor, prefer one creditor over another or wilfully defeat any obligation owed to a creditor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;25. In connection with the Company's entry into and performance of its obligations contained in the Documents, each of its authorised representatives has acted in accordance with his fiduciary and other duties to such Company under all relevant laws (including any relevant Foreign Laws) and the applicable articles of association (including in relation to any obligation to disclose a conflict of interest in connection therewith).

![](ex5-1img4.jpg)

**schedule 3**

**QUALIFICATIONS**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The obligations under the Documents will not necessarily be legal, valid, binding or enforceable in all circumstances and this Opinion is not to be taken to imply that each obligation would necessarily be capable of enforcement or be enforced in all circumstances in accordance with its terms. In particular, but without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the binding effect, validity and enforceability of obligations may be limited by laws relating to bankruptcy, administration, insolvency, moratorium, liquidation, dissolution, re-organisation and other laws of general application relating to, or affecting the rights of, creditors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) enforcement may be limited by general principles of equity. For example, equitable remedies such as specific performance or the issuing of an injunction are available only at the discretion of the court and may not be available where, for example, damages are considered to be an adequate alternative and we therefore express no opinion on whether such remedies will be granted if sought;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) claims may be or become barred under the laws relating to the prescription and limitation of actions or may become subject to the general doctrine of estoppel or waiver in relation to representations, acts or omissions of any relevant party or may become subject to defences of set-off or counterclaim;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the courts of the Cayman Islands may not enforce contractual provisions to the extent that the same may be illegal or contrary to public policy in the Cayman Islands (for example, a provision purporting to indemnify or exculpate a person for an action which constitutes actual fraud or a criminal offence) or, if obligations are to be performed in a jurisdiction outside the Cayman Islands, to the extent that such performance would be illegal or invalid or contrary to public policy in that jurisdiction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) a judgment of the courts of the Cayman Islands may be required to be made in Cayman Islands dollars;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the courts of the Cayman Islands have jurisdiction to give judgment in the currency of the relevant obligation and statutory rates of interest will vary according to the currency of the judgment. In a liquidation proceeding, the courts of the Cayman Islands will require all debts to be proved in a common currency, which is likely to be the "functional currency" of the party being liquidated determined in accordance with applicable accountancy principles. Currency indemnity provisions have not been tested, so far as we are aware, in the courts of the Cayman Islands and as such may not be enforceable;

![](ex5-1img4.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the courts of the Cayman Islands may decline to accept jurisdiction in an action where they determine that there is another more appropriate forum in another jurisdiction or that a court of competent jurisdiction has already made a determination of the relevant matter or where there is litigation pending in respect thereof in another jurisdiction or it may stay proceedings if concurrent proceedings are instituted elsewhere;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) there is a presumption that the courts of the Cayman Islands will give effect to an exclusive jurisdiction clause in an agreement and upon application, may stay proceedings brought in the Cayman Islands or grant an anti-suit injunction against a party that commences proceedings elsewhere where such proceedings are in breach of the exclusive jurisdiction clause, unless a party can satisfy the courts of the Cayman Islands that it would be just and equitable to depart from that presumption (for example, not to do so would deprive one party of access to justice);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any provision purporting to fetter any statutory power of a Cayman Islands partnership or company (for example, a provision restricting the company's power to commence winding up, to alter its memorandum and articles of association or to increase its share capital) may not be enforceable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) provisions that purport to require parties to reach agreement in the future may be unenforceable for lack of certainty;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) the courts of the Cayman Islands may find that a hybrid dispute resolution clause, though generally recognised under Cayman Islands law, is unenforceable on the grounds, amongst others, that it confers concurrent jurisdiction on an arbitral tribunal and the courts of the Cayman Islands;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) the courts of the Cayman Islands may refuse to enforce a provision that amounts to an indemnity in respect of the costs of enforcement or of unsuccessful proceedings brought in the Cayman Islands where such courts have already made an order to that effect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) where the courts of the Cayman Islands determine that a contractual term may be interpreted in more than one manner the courts may employ the one that is deemed to be most consistent with business and common sense;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) it is possible that a judgment (in the Cayman Islands or elsewhere) relating to a particular agreement or instrument would be held to supersede the terms of such agreement or instrument with the effect that, notwithstanding any express term to the contrary in such agreement or instrument, such terms would cease to be binding;

![](ex5-1img4.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o) the enforcement of contractual obligations may be limited by the provisions of Cayman Islands law applicable to agreements or contracts held to have been frustrated by events happening after the relevant agreement or contract was entered into; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(p) the enforcement of obligations may be invalidated or vitiated by reason of fraud, duress, undue influence, mistake, illegality or misrepresentation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. We offer no opinion as to whether the acceptance of, or the execution or performance of, the Company's obligations under the Documents will or may result in the breach or infringement of any other deed, contract or document entered into by, or binding upon, such Company (other than its articles of association).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. As a matter of Cayman Islands law:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) a provision for the payment of additional moneys or the forfeiture of property or rights for breach of a contractual obligation, whether expressed by way of penalty, additional interest, liquidated damages or otherwise, will be unenforceable if such a payment or forfeiture is held to constitute a penalty. We express no opinion as to whether any provision constitutes a penalty;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) certain terms and concepts (for example the difference between "negligence" and "gross negligence"), though commonly used, have not yet been clearly defined by the courts of the Cayman Islands;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written agreements are only effective from date on which they are signed notwithstanding that they may contain an earlier stated effective or "as of" date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) notwithstanding that it is expressly stated as such, a power of attorney or other grant of agency (including an agent for service of process) will not be irrevocable unless, as a factual matter, it is coupled with an interest or given to secure a proprietary interest of the donee or the performance of an obligation owed to a donee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) notwithstanding that a breach of the provisions of a document has caused or is likely to cause damage to a party thereto, or would, on the face of such document, give rise to a specified liability or consequence, a non-breaching party may be under an obligation to take reasonable steps to mitigate any loss and the Cayman Islands courts may take any failure to do so into account when determining whether or not to award damages or grant relief to a claimant;

![](ex5-1img4.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the courts may, in limited circumstances (primarily in relation to fiduciary-like or long-term arrangements) imply a contractual duty of good faith on parties, notwithstanding the absence of any such express term in a document;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) only in very limited circumstances (for example, deeds poll and/or where rights are held on trust), can a person who is not party to an agreement governed by Cayman Islands law enforce the terms of that agreement against one or more of the parties thereto, unless such person has been expressly granted the right in the agreement to enforce such terms pursuant to The Contracts (Rights of Third Parties) Act, 2014 of the Cayman Islands; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) a provision of an agreement that purports to impose obligations on a person who is not party to such agreement will not be enforceable against such person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. We offer no opinion as to the existence or value of, or any party's interest in, any property or assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. In order to maintain an exempted company in good standing with the Registrar, annual fees must be paid and annual filings must be made with the Registrar within the prescribed periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. A provision that a calculation, determination, opinion, exercise of power or certificate will be conclusive and binding may not be effective or enforceable if such calculation, determination, opinion, exercise of power or certificate is given unreasonably, arbitrarily or without good faith or which is fraudulent or manifestly inaccurate and will not necessarily prevent judicial enquiry into the merits of any claim.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. The question of whether or not any provision of an agreement or document which is illegal, invalid, unenforceable or void may be severed from the other provisions thereof would be determined by the courts of the Cayman Islands in its discretion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. We make no comment on references to any Foreign Laws or to any representations or warranties made in any agreement or document.

![](ex5-1img4.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. The effectiveness of terms releasing or exculpating any party from, or limiting or excluding, a liability (or duty otherwise owed) may be limited by law, and confidentiality obligations may be overridden by the requirements of legal or regulatory process or applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. Failure to exercise a right, or any delay in such exercise, may operate as a waiver of that right notwithstanding a provision to the contrary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. Under Cayman Islands law, the register of members (shareholders) is *prima facie* evidence of title to shares and this register would not record a third party interest in such shares. However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. As far as we are aware, such applications are rarely made in the Cayman Islands and for the purposes of the opinion given in paragraph 5.2, there are no circumstances or matters of fact known to us on the date of this opinion letter which would properly form the basis for an application for an order for rectification of the register of members of the Company, but if such an application were made in respect of the Class A Ordinary Shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. In this opinion letter, the phrase "non-assessable" means, with respect to the issuance of shares, that a shareholder shall not, in respect of the relevant shares and in the absence of a contractual arrangement, or an obligation pursuant to the memorandum and articles of association, to the contrary, have any obligation to make further contributions to the Company's assets (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. We express no opinion on any provision in any agreement or document requiring written amendments and waivers thereof insofar as it suggests that all or other modifications, amendments or waivers could not be effectively agreed upon or granted by or between the parties. It is likely that the provisions of an agreement or document governed by Cayman Islands law may be waived or amended orally or by conduct notwithstanding any such provision.

515 Madison Avenue, 8th Floor

New York, NY 10022

United States of America

Re: <u>Initial Public Offering of Units of Oceanhawk Acquisition Corp.</u>

To the addressees set forth above:

We have acted as special counsel to Oceanhawk Acquisition Corp., a Cayman Islands exempted company (the "***Company***"), in connection with the proposed issuance of up to 18,400,000 units of the Company (collectively, the "***Units***"), with each Unit consisting of one Class A ordinary share of the Company, $0.0001 par value per share (the "***Class A Ordinary Shares***"; the Class A Ordinary Shares to be included in the Units, the "***Shares***") and one right to receive one-fourth of one Class A Ordinary Share (the "***Rights***"). The Units, the Shares and the Rights are included in a registration statement on Form S-1 under the Securities Act of 1933, as amended (the "***Act***"), initially filed with the Securities and Exchange Commission (the "***Commission***") on March 20, 2026 (as amended, the "***Registration Statement***"). The terms "Units," "Shares" and "Rights" shall include any additional such securities registered by the Company pursuant to Rule 462(b) under the Act in connection with the offering contemplated by the Registration Statement. This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus (the "***Prospectus***"), other than as expressly stated herein with respect to the issuance of the Units, the Shares and the Rights.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter, including:

&nbsp;&nbsp;&nbsp;&nbsp;(a) the form of the underwriting agreement proposed to be entered into between the Company and the underwriters named therein that is filed as Exhibit 1.1 to the Registration Statement (the "  ***Underwriting Agreement*** "); and

&nbsp;&nbsp;&nbsp;&nbsp;(b) the form of the rights agreement proposed to be entered into between the Company and the rights agent named therein that is filed as Exhibit 4.4 to the Registration Statement (the "  ***Rights Agreement***" and, together with the Underwriting Agreement, the "  ***Transaction Documents*** ").

**May 20, 2026**

**Page 2**

With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We are only opining herein as to the internal laws of the State of New York, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction, domestic or foreign, or as to any matters of municipal law or the laws of any local agencies within any state. Various matters concerning the laws of the Cayman Islands with respect to the Units, the Rights and the Shares are addressed in the opinion of Carey Olsen Cayman Limited, which has been separately provided to you. We express no opinion with respect to those matters herein, and, to the extent such matters are necessary to the conclusions expressed herein, we have, with your consent, assumed such matters.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof:

&nbsp;&nbsp;&nbsp;&nbsp;1. When the Units shall have been duly registered on the books of the transfer agent and registrar therefor in the name or on behalf of the purchasers and have been issued by the Company against payment therefor in the circumstances contemplated by the Underwriting Agreement, the Units will constitute the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

&nbsp;&nbsp;&nbsp;&nbsp;2. When the Units shall have been duly registered on the books of the transfer agent and registrar therefor in the name or on behalf of the purchasers and have been issued by the Company against payment therefor in the circumstances contemplated by the Underwriting Agreement, the Rights included in the Units will constitute the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

Our opinions are subject to: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith and fair dealing, and the discretion of the court before which a proceeding is brought and (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy.

We express no opinion as to (a) any provision for liquidated damages, monetary penalties or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) consents to, or restrictions upon, governing law, jurisdiction, venue, arbitration, remedies, or judicial relief, (c) waivers of rights or defenses, (d) any provision requiring the payment of attorneys' fees, where such payment is contrary to law or public policy, (e) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights, (f) waivers of broadly or vaguely stated rights, (g) provisions for exclusivity, election or cumulation of rights or remedies, (h) provisions authorizing or validating conclusive or discretionary determinations, (i) proxies, powers and trusts, (j) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property, (k) any provision to the extent it requires that a claim with respect to a security denominated in other than U.S. dollars (or a judgment in respect of such a claim) be converted into U.S. dollars at a rate of exchange at a particular date, to the extent applicable law otherwise provides and (l) the severability, if invalid, of provisions to the foregoing effect.

With your consent, we have assumed:

&nbsp;&nbsp;&nbsp;&nbsp;(a) the issuance and sale of the Units and the Rights has been duly authorized by the Company, and the Transaction Documents have been or will be duly authorized, executed and delivered by the Company and the other parties thereto;

**May 20, 2026**

**Page 3**

&nbsp;&nbsp;&nbsp;&nbsp;(b) the Company (i) is duly incorporated and is validly existing and in good standing, (ii) has requisite legal status and legal capacity under the laws of the jurisdiction of its organization and (iii) has complied and will comply with all aspects of the laws of the jurisdiction of its organization in connection with the transactions contemplated by, and the performance of its obligations under, the Transaction Documents;

&nbsp;&nbsp;&nbsp;&nbsp;(c) each of the Transaction Documents constitutes or will constitute a legally valid and binding obligations of the parties thereto other than the Company, enforceable against each of them in accordance with their respective terms;

&nbsp;&nbsp;&nbsp;&nbsp;(d) neither (i) the execution and delivery by the Company of the Transaction Documents nor the performance by the Company of its obligations thereunder or (ii) the issuance and sale of the Units or the Rights: (i) conflicts or will conflict with the Memorandum and Articles of Association of the Company, (ii) constitutes or will constitute a violation of, or a default under, any lease, indenture, instrument or other agreement to which the Company or its property is subject, (iii) contravenes or will contravene any order or decree of any governmental authority to which the Company or its property is subject or (iv) violates or will violate any law, rule or regulation to which the Company or its property is subject (except that we do not make the assumption set forth in this clause (iv) with respect to the laws of the State of New York); and

&nbsp;&nbsp;&nbsp;&nbsp;(e) that the status of the Units or the Rights as legally valid and binding obligations of the parties will not be affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders or (iii) failures to obtain required consents, approvals or authorizations from, or to make required registrations, declarations or filings with, governmental authorities.

This opinion is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act. We consent to your filing this opinion as an exhibit to the Registration Statement and to the reference to our firm in the Prospectus under the heading "Legal Matters." We further consent to the incorporation by reference of this letter and consent into any registration statement or post-effective amendment to the Registration Statement filed pursuant to Rule 462(b) with respect to the Units and the Rights. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.

Sincerely,
