1. Time policy – When the insurance is made for a specified length of time, the implied warranty is not complied with unless the vessel is seaworthy at the commencement of every voyage it undertakes during that time;
2. When the insurance is upon the cargo which, by the terms of the policy, description of the
voyage, or established custom of trade, is to be transshipped at an intermediate port, at
the commencement of each particular voyage;
3. Where different portions of the voyage are contemplated, at the commencement of each
portion;
4. When the ship was unseaworthy at the commencement of the voyage but becomes
unseaworthy during the voyage to which an insurance related, and unreasonable delay in
repairing the defect exonerates the insurer on ship or shipowner’s interest from liability
from any loss arising therefrom.
