20ft outriggers

Posted by Brian Cunningham on Dec 27, 2006

The large so I can fly both the other float and the kayak. Each float will support the weight of the boat. That's a lot more righting moment. I could have used a bigger kayak, but this one keeps the weight down. Multihulls get their speed from being light. The floats are also 20ft apart! So again, a lot more righting moment. 10ftx600lbs=6,000ft-lbs of righting moment. I'm running 300sqft of sail on the rig. The crossbeams are 15in high at the center to cope with the loads.

The link below is a multihull FAQ, a good read for beginners.
