ABANDONMENT of a Vessel. Deserting and abandoning her by reason of unseaworthiness or danger of remaining in her, also when grounded and cannot be saved. This never occurs but in imminent cases; therefore, before the insured can demand recompense from the underwriter, they must cede or abandon to him the right of all property which may be recovered from shipwreck, capture, or any other peril stated in the policy. Other parties entering and bringing the vessel into port obtain salvage. (Vide [Derelict].)
