You cant. Atleast not from me. My father and I made it about 4 and a half years ago. he made a plug out of a big chunk of nylon, and then we made a mold using the plug. We used the mold to pull three cowls from it, then 3 years later he says he cant find the mold (threw it out) and doesnt have time to make another. Of the three cowls, the first one was way to thin and light.. it got trashed. the second one is what you see on the boat. and the third sold on ebay 3 years ago, for 8 bucks :blink: I really wish we still had the molds.... it was a nice cowl!
That is one of the first outriggers I ever made years ago, it didnt work to well and it is now on my "Wall Of Dead Wood" I destroyed the cowling, trying to make it fit another design about a year later....

(sorry, probably WAY more info than you wanted, but thats the story behind the cowl...)
P.S. we got the basic shape from the old BBY riggers that Randy Naylor used to make, he used to make them in fiberglass and may still have some, you could give him a shout.
