What is referred to as extra payment made to the captain for special services?

Primage refers to the additional payment made to a captain for special services provided during the voyage. This payment is typically given as a reward for exceptional services, such as ensuring the safe delivery of cargo or navigating challenging waters. It serves as an incentive for captains to perform their duties with a heightened level of diligence and care, recognizing their role's importance in the overall success of a maritime operation.

In this context, primage is distinguished from other maritime terms. Demurrage pertains to charges incurred for cargo that remains in the possession of the carrier beyond the agreed-upon time, while freight denotes the payment made for the transportation of goods by a vessel. Lay days refer to the specified period allowed for loading and unloading cargo without incurring additional charges. Each of these terms has its own specific implications in maritime commerce, but primage specifically indicates a bonus or extra payment for the captain's special contributions.
