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.
When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.
