What is Seamanship?

Seamanship is the art of operating a vessel. Specifically, it is a compilation of the skills and knowledge entailed in navigation, boat handling, maintenance, and the law of the sea. It involves working as part of a crew and when the occasion arises, leading a crew in the role of a skipper. 

Seamanship involves every aspect of a boat from being tied up to the dock to the operation in open water.  A proficient seaman creates a culture of awareness, safety, and confidence in the crew and the operation of a vessel at all times.  

Seamanship involves leading, teaching, managing, navigating, and maintaining all aspects of the operation and activity aboard the vessel.
