How is a 'sailing vessel' defined?

A 'sailing vessel' is defined as a vessel that uses sails for propulsion. This definition emphasizes the primary mode of propulsion, which is the use of sails to harness wind energy for movement through the water. In the context of maritime regulations and the COLREGs (International Regulations for Preventing Collisions at Sea), this distinction is important because it categorizes vessels based on their propulsion methods, effectively guiding navigational rules applicable to different types of vessels.

While some vessels may have auxiliary engines and can be operated with or without sails, the definition focuses specifically on those that utilize sails as the main source of propulsion. This highlights the significance of wind in the operation of sailing vessels and helps in understanding their navigation rights and responsibilities under maritime law. In contrast to the definitions that suggest mechanical propulsion or non-motorization, this particular definition captures the essence of what constitutes a sailing vessel in maritime terminology.
