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.
The Pacific Pilotage Authority says: "There is a common misunderstanding amongst vessel operators that vessels built prior to 2012 are exempt from some of the requirements for pilot transfer arrangements. This is incorrect...".
Study from 2015: Psychological stressors, in addition to the physical demands associated with the role (e.g., reduced sleep, boarding, and departing vessels), may over time have a damaging effect on pilots' physical and mental health.
