Copy from a post from some 2 to 3 weeks back. The are David Swingles comments on spi-ing from the tramp bag :



As far as spin launching, I’ve been very successful solo tramp launching out of the Goodall supplied bag. Slowly I will work into heavier winds doing this, but so far, piece of cake in less than 10 kts. Wouter had a good writeup a while back. Key points were get close to downwind, don’t gybe, get chute out of bag, hoist quick. Takedown is opposite, except throw the halyard in the water over rear crossbar to untangle/untwist and provide slight tension as you get the monster on the deck. The real point here is there should be no problem tramp launching this thing with crew.
