I have whats called a Waterdawg Kustomz hull, it is a stand up jet ski. It is made of carbon fiber with a fiberglass core. I have a bit of a project going on right now. The rear of the sky has a "sealed" cavity filled with foam that got somewhat waterlogged. I cut open the ski, removed all the foam, sealed it and foamed it. Now I am reinstalling the tray but im unsure how many layers of carbon fiber to use. I ordered some 19.7oz 2x2 twill from US Composites. I cut out 2 pieces for the bottom and for the gunwhales I am thinking 2 pieces as well. How would you go about doing this? Here's some pictures so it's easy to understand. The last photo isnt laid down yet, it's just 2 layers I cut out.

Thanks. Good to hear 2 layers will be plenty. The enclosures on the sides are called "footholds" and are installed after the hull is assembled. Hard to see since they are enclosed, but they extend far foward in the tray. Would 4-6" strips layed over those cuts be suffice? Sorry about all the questions; not everyday I cut into a $7000 hull
