Designer: Justin Andrej
CONCEPT
The Enavigo 36 DAY SAILER is a product of modern yacht design and the latest boatbuilding technologies. Combining high tech materials with traditional yachtbuilding skills produces a blend of racing boat performance with classic yacht aesthetic values.
DESIGN
The hull and appendages are optimised for CFD and VPP:
HULL
The plumb bow, moderate beam, classic but hydrodynamically efficient stern profile, perfectly balanced volume distribution and maximized dynamic waterline length guarantee optimum sailing trim and speed.
APPENDAGES
The T keel combines a very low CG with efficient high aspect ratio foil. Together with the efficient spade rudder this makes the yacht stable and easy to handle in all sailing conditions.
