Ladies and Gentlemen, \ r \ nThe wings are mounted on a 15hp, 4 stroke Mercury outboard. \ R \ nThe boat is approximately 4.5m x 1.78m made of fiberglass, about 220 kg. Type \ "From Wiek \ "From the boatyard in Wiek on Rügen. \ r \ nBoot comes up immediately at slow speed rear, so that forms little suction. Comes very fast to glide and holds the sliding phase at about half throttle, therefore, an optimal gasoline consumption. \ R \ nEnd result; These wings are optimal for this engine and boat sizes of other types, that's my practical experience. \ R \ n \ r \ nMfG M.
