Gday all. Hopefully this will tell a half interesting story following the construction of my first mini-yacht. Here are a couple of stats from the top of my head:

Wheelbase: as per a blokart (1.65 x 1.4)
Frame: 30x30x3.0 and 30x30x2.0 steel
Mass aimed for: about 30kgs (35kgs with largere rear wheels)

Anyway, Ill get more details as I keep building. First image here is what it looked like as an experimental testbed. I was a little unsure of the power availible from the windsurfer sail but tests proved it should provide enough horsepower to play with.



Testing was conducted in the small paddock pictured as everywhere else is too rough. I flipped it twice due to a limited turning circle. Manouverability is much improved in the current rebuild. Mainsheet was a piece of cord run through a single pulley.



Here is the frame prior to final modification. The mast step has been removed, rear axles are still present and the steering geometry hasn't been corrected.



And finally finshed, all up I spent a short evening working the kinks out.
