SWATH is a hull technology developed as early as 1938, which was previously reserved for special ships. Two torpedo-shaped floats under the water surface generate the buoyancy of the ship. The resulting wave decoupling reduces the rolling and heeling behaviour of the yacht by up to 90 percent compared to conventional ships. The process for reducing vertical movements under sea conditions is similar to that of semi-submersible vessels (construction of oil platforms).
The wave motion, which is strongest at the water surface, decreases with increasing depth. The desired effect of this design is a significant minimization of heel and roll angles due to a much smaller waterline area (e.g. compared to a catamaran of the same size). The area that can be affected by a wave is therefore much smaller. Actively controlled fins also support the stability of the vessel. The stability of the floating object is therefore less affected by surface currents and waves than with classic construction methods. With the use of SWATH technology and the resulting much smoother sailing characteristics, you no longer have to worry about seasickness.
