In a new 15 m long boat, with new, but traditionally designed, seats and spring mechanisms, the driver was exposed to up to 7 g many times per minute. In the 6 m experimental boat, equipped according the new concept, the driver in the saddle was never exposed to more than 1 g, while the co-driver in a regular seat was continuously, simultaneously subject to 3 g or the same impact as the hull. The results made it necessary to develop a new kind of spring- and damping mechanism. This has been done successfully and the new mechanism is an integrated part of the concept. Three factors made the Swedish Coast Guard adopt the new concept as a standard.
Drivers report better control of vessel.
Crew feel safer and more at ease. Crew report less back pain and discomfort in rough sea. Continuos development of different parts of the system is done in cooperation with Johan Ullman M.D., who is a Ph.D. student at the div.f. Occupational Orthopaedics, Sahlgrenska University Hospital and scientifically evaluates the concept as a part of his thesis.
