What entity provides guidance regarding synthetic towing hawsers and end fittings?

NAVSEA, which stands for the Naval Sea Systems Command, is the correct entity that provides guidance regarding synthetic towing hawsers and end fittings. This organization is responsible for the development and supervision of naval ship systems, and it issues technical regulations and recommendations that ensure safety and operational effectiveness in naval operations.

Their guidelines are crucial for maintaining the integrity and performance of towing systems, especially as it involves synthetic materials that may have different characteristics compared to traditional steel. This encompasses not only the specifications for the materials themselves but also the appropriate designs for fittings and connections necessary for safe towing operations.

The other entities, while important in their own rights, focus on different aspects of naval operations. For example, the Chief of Naval Operations (CNO) primarily sets the overall operational strategy and policy for the Navy, while the United States Coast Guard (USCG) is concerned with maritime safety and the enforcement of maritime law. The Secretary of the Navy (SECNAV) oversees overall Department of the Navy policies and resources but does not provide specific technical guidance on synthetic towing equipment. Thus, the guidance on synthetic towing hawsers falls under the purview of NAVSEA.
