The reasonable fitness of a vessel in all respects to encounter the ordinary perils of the contemplated voyage, properly crewed, provisioned and equipped. Seaworthiness is implied in voyage policies, but not in time policies. A shipowner’s right of claim under a time policy is prejudiced if he knowingly goes to sea in an unseaworthy condition. Cargo policies waive breach of the warranty except where the insured is privy to the unseaworthiness.
