1-Both-to-Blame Collision Clause
(Definitions)
a-When two vessels collide, they become liable to each other proportionately for the total damage. The vessel with the lesser damage may impose upon the cargo being carried to contribute to the amount to be paid to the other vessel. The "Both to Blame Collision Clause" in the cargo policy provides that in such event, the cargo policy will cover such contribution. See "Collision Clause" and "Cross Liabilities."
