We bought a pile of catamaran parts on craigslist,
tied it all together, and pulled it around SF Bay with a 21 meter kitesurfing kite. All in just a few short hours

hey- give me your old sailboat and windsurf junk to build into the next experiment. I'm in Emeryville, CA. Send email to robot(at)mit.edu

Step 1: Shopping for Parts

Nick, Saul and Tim are out craigslist shopping.

No, I guess we won't buy the motorcycle.

Howabout we buy that pile of catamaran parts instead?
It looks like the remains of two hobie cats.


My God! what have we just done?
How does the kite attach to the boat? Sounds like it's a 5 line SLE kite?
Oh my god, that's hilarious! I've carried stuff like that on top of sedans and coupes, but with a truck it's even funnier, since it even makes the truck look small.
It would have been much quicker to use one of Eric's "sleeping bags" as a tramp no?
Ha! All those foil kites are precious to me -- even the broken ones! On second thought, a piece of fabric over the wooden-spar trampoline would have been a good idea. While leaning way over the rear to wrestle with the barely functioning rudders during kite-loop jibes, it was too easy to get my whole leg shoved in and stuck between spars. Falling off the boat at that moment would probably twist a knee pretty badly. Closer spar spacing would also do it.
I suggested the fabric covering idea, but we probably wouldn't have made it out that evening if we'd tried it. (Actually, I was guilty of expressing a severe lack of optimism about finishing that day -- and was happy to be proved wrong!) But about the fabric -- I'm no longer sure it would have would have been a total plus. Having lots of things to grab ahold of was pretty important, given the tiller force I was exerting and the amount of water swooshing around. Maybe weaving more innertubes among the spars ... I'm sure I've gone faster under sail -- in much bigger boats. But never in my life have I felt a sailboat accelerate under me as rapidly as that beat-to-sh*t old Hobie. Exhilarating!
2" square fishing net
or a hobie cat with a still-present trampoline would do the trick nicely :D
Very cool all the same, I should get back on the cat project I started last year. Foils precious to me also, but cant fly the v19 anymore. After the winter winds its like going for a bike ride on vallium.
Cool! Great Instructable! Thanks Joe
Cool, <br/><br/>My friend is developing a kite system with rigging for kite powered boats. He has some awesome videos on <a rel="nofollow" href="http://www.youtube.com/profile?user=kiteforsail">youtube</a>.<br/>www.kiteforsail.com<br/><br/><div style="margin-left:15px;"> <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/LpG6o74pQnM"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/LpG6o74pQnM" type="application/x-shockwave-flash" width="425" height="344" wmode="transparent"></embed></object></div><br/>
WoW! that boat rocks! you should circumvavigate the earth on it.
Sheer awsomeness. I've been wanting to do just this for ages but have been constrained by a severe kite deficiency. Nice job.
