Additional Perils Clause Law and Legal Definition

Additional perils clause is a clause in a marine insurance policy that protects against risks caused by sailor’s negligence or a latent defect in machinery. It includes losses from latent defects and the negligence of the crew provided the owner has used due diligence to provide a seaworthy vessel. Additional perils clause is also known as Inchmaree clause, named after the British ship Inchmaree whose sinking in 1884 gave rise to litigation that led to the clause bearing its name.
