Quick Summary

A deviation warranty is an implied promise in ocean marine insurance contracts. It stipulates that a ship must not deviate from its customary route between its designated ports of call. This warranty is crucial because any unagreed-upon departure from the intended course can void the insurance coverage, unless the deviation is to save lives. In common-law legal systems, a deviation can also make a carrier liable for damages related to delays in delivering goods.123
