Which of the following positions is NOT part of the 5 Boat Crew positions?

The position that is not part of the standard 5 Boat Crew positions is the Navigator. The five recognized roles usually include the Coxswain, Engineer, and Crewman, among others designated for specific duties on a vessel.

In a typical boat crew, the Coxswain serves as the person in charge, responsible for the overall operation of the vessel and the safety of the crew. The Engineer oversees the mechanical and operational integrity of the boat's systems. Crewmen assist in various operational tasks and can rotate through different roles as required during the mission.

While navigation is crucial in maritime operations, in this context, the responsibility for navigation may be performed by the Coxswain or integrated with crew responsibilities but is not recognized as a distinct, formal position within the standardized boat crew structure. Therefore, while navigation is essential to boat operations, it does not define a specific role within the five essential positions typically assigned on a boat crew.
