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
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?
Step 2: Assembly
Step 3: Lashing the Platform
Step 4: More Lashing
Step 5: Almost Done
Step 6: Finished
Actually all the crossings need to be lashed or at least laced together or
the sticks will break one at a time. If they're tied together it's more like a basket
or an "e pluribus unum" which the Romans also called a "Fasces".
Step 7: Let's Go to the Beach.
Step 8: Pump It Up
Saul designs them for monkeykites.com
Step 9: Ulla With the Kite
Step 10: Launching the Kite
kitesurfingschool.org will reveal what that is.
In stronger wind we'd hook the bar to the boat first,
cuz the kite would be oversized for a mere human.
Step 11: Sailing!
One guy on the kite, one on the rudders, and one ballast monkey.
The kite's chickenloop is attached to the mast step of the catamaran with a wichard release. The kite's main safety line (5th or wingtip safety rig, your choice) passes through another wichard release and has a big ball on the end that's really easy to pull. (by accident, even)
Step 12: Landing
Step 13: Keys Locked In
Ulla left her keys in the trunk, so she called aaa to open it.
The guy pried the window open a bit with a wooden wedge and pulled the knob with a folded piece of fiberglass box strap. Amazing. That stuff really does have a use after all.
And a good time was had by all!
