Most maritime claims are dependent upon the ownership of the vessel. The vessel can only be arrested provided that the party who was the owner at the time that the cause of action arose is still the owner at the time of arrest. Maritime liens can however be enforced irrespective of ownership and entitle the claimant to issue a claim and to arrest the vessel despite a change of ownership. Maritime liens apply only to claims for salvage, crew wages, damage done by a vessel and Master’s wages and disbursements.
