continuing the journey
The wingmaran 14 is the first test boat that I have made and the first wingmaran to be built and tested since my father’s prototype #5 which he built in the late 1980’s. I contemplated the best shape for the hull for about 5 years. I settled on a narrow, flat bottomed scow. It is very much like a windsurfing board with 14” of height. There is a slight concave section in the stern which prevents the stern from being sucked downward. The rocker is very subtle except at the bow. Unlike a planing dinghy, you do not need the bow to pitch upwards to get on plane, rather, you want the hull to remain pitch neutral. This allows the angle of attack of the wing to be at the ideal pitch. I have learned a lot from building and testing this prototype and have incorporated all my incites into the design of the Wingmaran 15 (now available) and the up coming Flying Skiff 13 and Wingmaran 15X.
Beam Reach to Down Wind Run
Everything came together on the third test run. I successfully pushed the limits of the boat over the hump speed and into hydroplaning mode. I reached a speed of 13.7 mph (12 knots) on a broad reach with only a 75 square foot sunfish rig which was not even properly attached.
Moreover, the Wingmaran 14 should be able to handle a larger sail, in the 90-100 square foot range. A 96 square foot sail has been designed and testing is in the works. A laser sail rig or a Force 5 sail rig would also be good choices for this boat. The boat features 2 mast step holes to accommodate different sized rigs.
upwind tacking
Here is a video of the first time I tacked into the wind. It is also minutes before I hit the high speed of 13.7 mph. This day I had forgotten to connect the end of the boom to the traveler which caused the boom to rise. My purchase on the sail was only 1 to 1 instead of 2 to 1. But the boat still managed a speed of 8mph tacking into the wind.
