Chris Green could tell you about a fellow I met, who put a rather large parasail on a cat sailboat. He had a dentists looking chair mounted on it to control the parasail from.
Chris drove, they gave it a go a few times at the TX City Dike, years ago.
Then I heard he bought Michael Yosts N6.0, modified it, and had it out in California somewhere last I heard.
He sold me the mast, which I then used on my N6.0 in the avatar. It had broken a speader bar, and toasted the mast.
It's now still on the boat, with the current owner.
Anyways, I forgort his name, but he was really getting into the modding and parasail thing.
I hope Chris Green will chime in.....
