< Back to all designs
The design brief was for a good all round ocean racing yacht with the emphasis on long passage races where a predominance of reaching and running conditions could be expected, but also a yacht that would be fast for its size for harbor and gulf racing, using handicap systems other than IOR.
Performance for size and IOR handicap honors are conflicting parameters which required a compromise difficult to attain, and made more so by changes in the Rule during the design process. Proposed changes to the Rule changed themselves three times during construction of the first boat to Design No. 60 - ZAMAZAAN - requiring considerable use of the crystal ball. Major changes made during that time were a switch from the planned drop keel in favor of a fixed keel, slight increase in displacement, considerable change in the aft section because of the proposed Rule changes there, and a slight change in the forward depth area where the dimension was to be restricted.
The rig is fractional with large main and smaller foretriangle. The keel is a high aspect ratio minimum thickness foil with computer developed sections to produce required lift with as little drag as possible.
ZAMAZAAN continues to be a dominant force in the IOR racing scene in her home port, San Francisco, Ca., and races off the West Coast of USA and in Hawaii - a testimonial to the carefully composed compromise during design.
