Courtesy of Krist Kustoms Common Fleece, available in any fabric shop is one of the best tricks" for creating fiberglass hulls. The fleece can acutually take the place of the fiberglass mat! Before you continue, read "Fiberglass Hulls: PAM Mold Release" Once you have created the hull's "skeleton" (like you were making a wooden boat); stretch heavy fleece over the hull (using staples). Make it is as tight as you can (you should be able to use your boat as a drum). As you are doing this, it is important to remember to make the fleece look as you intend your hull to finally look! Once the fleece is completely stretched over the boat; start painting the fiberglass resin into the fleece. It will take a LOT of resin. After it is dry, remove the staples and pull the hull from the mold. (Did you use PAM?) Now, you can use fiberglass MAT to add extra layers, if desired.
