FountainePajot catamarans are equipped with keel instead of a centerboard.
Keel has the following advantages: there is no necessity for management, it excellently protects the screw, a total line, a rudder and a bottom of the hull at the moment of touching ground.
Besides, at the expense of absence of mooring wells the gabarits of internal premises are more spacious. In the special wind tunnel keel profile is tested. They do not create vibration and turbulence thanks to what velocity qualities of vessels are considerably improved.
Keel is completely independent detail, keeping water resistance and structure of a catamaran even at maximum strong blows.
