Nautical Term: GLS

Definition of GLS

Gearless (GLS) is a nautical term used to describe a propulsion system on a sailing yacht that does not rely on traditional gearboxes. Instead, GLS systems use direct drives, which can result in increased efficiency, lower noise levels, and reduced maintenance requirements.

For example, consider a modern luxury sailing yacht that utilizes a gearless propulsion system. The yacht’s captain, as he navigates the yacht through the serene waters of a secluded bay, can marvel at the quiet efficiency of the yacht’s gearless propulsion system.
