The best of wave piercing planing catamaran and displacement
hull
New ideas are important.
But final performance only is proved after testing and optimizing
in practice.
The TOUCHWATER
semi-displacement sport catamaran results from various tests
of several previous constructions. Hull drag is optimized in
combination with allocation of buoyancy. The semi-displacement
hulls effect a dynamic lift of the boat while riding and give
quite a lot of agility. By hydrodynamic optimization the trim
of the boat remains stable and is independant of the flow conditions
in transition from displacement to semi displacement / planing
mode.
Two boat types got special attention while developing the TOUCHWATER
semi-displacement design:
