I also have a sport 20 In prints with a fiberglass cowl (no build sheet,haven't had time to do one).Been trying to get the sport 20 epoxyglass hull done .The epoxy one in the pic came out a little crappy "OK" alot crappy"but salvageable,it was the very first one out of the mold + it's my first time learning how to mold a whole hull(got the cowls down great), need time to work out some of the kinks & processes(had hard time with the vacuum equipment and how much material to use) to make a good product before I can offer them to the public. Hopfully soon,"yea I have been saying this for a year &1/2 now" But I'm getting there.
