                               CERTIFICATIONS
                               --------------

I, John H. Westerbeke, Jr., certify that:

1.    I have reviewed this quarterly report on Form 10-Q of Westerbeke
      Corporation;

2.    Based on my knowledge, this report does not contain any untrue
      statement of a material fact or omit to state a material fact
      necessary to make the statements made, in light of the circumstances
      under which such statements were made, not misleading with respect to
      the period covered by this report;

3.    Based on my knowledge, the financial statements, and other financial
      information included in this report, fairly present in all material
      respects the financial condition, results of operations and cash flows
      of the registrant as of, and for, the periods presented in this
      report;

4.    The registrant's other certifying officer(s) and I are responsible for
      establishing and maintaining disclosure controls and procedures (as
      defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
      registrant and have:

      (a)   Designed such disclosure controls and procedures, or caused such
            disclosure controls and procedures to be designed under one
            supervisor, to ensure that material information relating to the
            registrant, including its consolidated subsidiaries, is made
            known to us by others within those entities, particularly during
            the period in which this quarterly report is being prepared;

      (b)   Evaluated the effectiveness of the registrant's disclosure
            controls and procedures and presented in this report our
            conclusions about the effectiveness of the disclosure controls
            and procedures, as of the end of the period covered by this
            report based on such evaluation; and

      (c)   Disclosed in this report any change in the registrant's internal
            control over financial reporting that occurred during the
            registrant's most recent fiscal quarter (the registrant's fourth
            fiscal quarter in the case of an annual report) that has
            materially affected, or is reasonably likely to materially
            affect, the registrant's internal control over financial
            reporting; and

5.    The registrant's other certifying officer(s) and I have disclosed,
      based on our most recent evaluation of internal control over financial
      reporting, to the registrant's auditors and the audit committee of
      registrant's board of directors (or persons performing the equivalent
      function):

      (a)   All significant deficiencies and material weaknesses in the
            design or operation of internal control over financial reporting
            which are reasonably likely to adversely affect the registrant's
            ability to record, process, summarize and report financial
            information; and

      (b)   Any fraud, whether or not material, that involves management or
            other employees who have a significant role in the registrant's
            internal control over financial reporting.
