War Risk Insurance: Insurance issued by marine underwriters against war-like operations specifically described in the policy. In former times, war risk insurance was taken out only in times of war, but currently many exporter cover most of their shipments with war risk insurance as a protection against losses from derelict torpedoes and floating mines placed during former wars, and also as a safeguard against unforeseen warlike developments. In the United states, war risk insurance is written in a separate policy from the ordinary marine insurance; it is desirable to take out both policies with the same underwriter in order to avoid the ill effects of a possible dispute between underwriters as to the cause (marine peril or war peril) of a given loss.
War Risk: The possible aggressive actions against a ship and its cargo by a belligerent government. This risk can be insured by a marine policy with a risk clause.
Warehouse Receipt: A receipt of commodities deposited in a warehouse, identifying the commodities deposited. It is non-negotiable if permitting delivery only to a specified person or firm, but it is negotiable if made out to the order of a person or firm or to a bearer. Endorsement (without endorsement if made out to bearer) and delivery of a negotiable warehouse receipt serves to transfer the property covered by the receipt serves to transfer the property covered by the receipt. Warehouse receipts are common documents in international banking.
Warehouse-to-Warehouse: A clause in marine insurance policy whereby the underwriter agrees to cover the goods while in transit between the initial point of shipment and the point of destination, with certain limitations, and also subject to the law of insurable interest. When it was first introduced, the warehouse-to-warehouse clause was extremely important, but now its importance is diminished by the marine extension clauses, which override its provisions.
Web Lashing: Webbing made of artificial fibre which is tightened and locked with a winch.
