Dan Wilkinson designed and built a dozen or so of these compact but roomy boats in the late 1970s and early 1980s in Sarasota, FL. Like her comps, the Coquina Cat is designed with some nontraditional twists. One such twist not shared with her comps is her keel-centerboard arrangement, using a long, narrow board that is housed totally below the cabin sole. (Her comps both have traditional centerboard trunks splitting the cabin more or less in two.) Best features: The high-aspect board should help with upwind performance, and her long waterline should give her a bit more speed than her comps. Her high, crowned cabin provides more headroom, and her wider beam gives her extra elbow room, revealed in her relatively high Space Index. Worst features: We worry that her small rudder might lead to control problems in heavy weather. Her small-diameter wheel on a pedestal might accentuate such problems. We'd rather see a traditional tiller in a boat this small, though it may take careful adjustment of her board, and early reefing, to avoid excessive weather helm and the danger of inadvertent broaching.
