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.
In 2020, the Swedish Maritime Administration, Sjöfartsverket commissioned three new pilot vessels to replace retired vessels in its Gothenburg, Marstrand, and Lysekil locations on the country’s west coast.
