Full sets of plans have been sold worldwide to a number of individuals with greatest numbers in Germany, Japan, USA, South Korea, Poland, France, Belgium, Russia, Spain, Uruguay.
The yachts carry corrector weights to bring them to 50 kg and they are a skiff design that aquaplanes both upwind and downwind except in very light conditions.
In 8 knots they will plane easily on reaches but are sailed in a displacement mode upwind and downwind.
In strong winds of 25 knots or more they are difficult to sail and extremely exciting, with numerous capsizes suiting summer venues with warm water.
The yachts sail best upwind if they are allowed to point a little lower than the theoretical maximum and this gives much better boat speed so that the VMG (Velocity made good) is maximized.
