What Does Both-to-Blame Clause Mean?

Insuranceopedia Explains Both-to-Blame Clause

Despite advancements in technology, shipping accidents still occur at sea. When they do, it is possible for both captains of the ships to be at fault. For example, if each captain leaves the helm of their ship unattended and the vessels collide, both parties may share responsibility for the accident. If both parties have ocean marine insurance policies that include both-to-blame clauses, each party will bear a portion of the losses resulting from the incident.
