Which of the following is not a clause found in the Ocean Marine policy?

The correct answer is that the Port of Call Clause is not commonly found in Ocean Marine policies.

Ocean Marine insurance typically includes various standardized clauses that address the unique risks associated with marine transportation. Among them, the General Average Clause is a critical component, which outlines the principles of shared loss among ship owners and cargo interests when an extraordinary sacrifice has been made to save the vessel and its cargo. The Comprehensive Clause is also recognized in marine insurance, though it usually refers to broader coverage options that encompass various perils.

However, the National Council Clause does not exist in conventional Ocean Marine policies as a recognized or commonly used clause. Instead, the term may refer to other organizations or frameworks that do not specifically relate to marine insurance. Thus, the Port of Call Clause is the correct answer because it is not a standard component included in Ocean Marine policy structures.
