At the A&R shipyard in Germany, the successful principle of SWATH boats was further developed in 2013: The SWASH principle allows sea-going, smaller and more economical boats.

SWATH and SWASH are interesting technologies that allow a vessel to sail much more calmly in high waves. A stable and calm position of the ship is especially important for pilot boarding.

Compmillennia LLC (Washington, North Carolina, U.S.A.) has delivered its Lightspeed® 41 (15.5-meter) Pilothouse catamaran, featuring strong but lightweight all-composite construction with a 42-knots achieved by twin 300-hp V8 Mercury Seapro outboard engines.

Following a pilot at fast speed

This my attempt to do just that. This is a summary of all scientific papers and articles that I could find about the ship’s pivot point. I have added links to any videos associated with the publications and have also included any useful diagrams or equations that the authors published to help explain their research.
