Which of the following is NOT an implied warranty in an Ocean Marine Insurance contract?

In the context of Ocean Marine Insurance contracts, various implied warranties ensure that both the insurer and the insured meet certain conditions to maintain the validity of the insurance coverage. Among these, the implied warranty that the vessel must not deviate from the predetermined route, the voyage must be legal, and the vessel must be fit for voyage are all explicitly recognized as critical protections that insurers rely upon to avoid undue risk.

However, the notion that the owner must guarantee the cargo value does not exceed a limit is not inherently an implied warranty within these contracts. Instead, this obligation typically falls under the realm of express warranties, where specific terms might be negotiated and articulated in the policy itself, defining the insured amounts and conditions of coverage for the cargo. Implied warranties generally focus on the state and conduct of the vessel and voyage itself, rather than stipulating the value of the goods being transported. Consequently, this makes the assertion regarding the cargo value the correct choice, as it does not align with standard implied warranties in Ocean Marine Insurance.
