Sparkman & Stephens and Derecktor shipyard teamed up to produce this 70’mini-maxi sloop for a veteran ocean racer. The ultimate IOR-racer at the time of her launch, OBSESSION'S design reflects S&S’s extensive use of hydrodynamic and finite element analysis. Her hull structure was optimized within ABS Offshore Racing Yacht Rules by making extensive use of weight saving titanium, a first for the mini-maxi class. According to her owner the S&S efforts to eliminate unnecessary weight have produced a yacht that sails much like a One-Tonner in that she is quick to reward carefully balance and sail trim finesse on the part of her crew. In the talent laden mini-maxi class, she won her class in the Manhasset Bay Fall Series and took line honors in the 1986 Miami-Palm Beach Race.
