QueeQueg 18

Indian summer is officially over around here, and thoughts turn to winter projects in the workshop. I've worked up a little trimaran design, inspired by Solway Dory's Osprey and Chris Ostlind's XCR.

It's an 18' stitch and glue plywood, 5 panel hull, with tortured ply amas and aluminum akas. Hull beam is 30". sail area: 118 sq. ft. a high aspect leeboard would be included (not shown). It would be fun to day sail, and might make a good little camp cruiser.

FreeShip Walap

I've found a way to force the freeware boat design softwareFreeship 2.6 to do proas, it may interest proafile readers.

The problem is that such programs assume that the port and starboard sides are mirror images of each other, so you can build a catamaran or a trimaran, but not a proa. Then I remembered that proas *are* symmetrical, only the axis of symmetry is turned 90 degrees.

The trick is simple: begin with the default design, and set the measures to say, 6 meters WIDE and 0.5 meter LONG. the hull will look weird at first, but once you move the control points around, it becomes pretty normal.
