High speed jetskis exert a lot of force on the hull, this jetski suffered sever hull damage after colliding with something underway. This caused a large part of the fiberglass hull to de-laminate.  Being underneath the ski was lifted onto work stands for access to the repair. Once the area was prepared, the double-bias cloth patches were cut and laid in order ready for laminating. The repair was glassed using high strength epoxy resin and then fairing compound was applied. This is all the owner wanted us to do as he was going to finish the cosmetics of the repair himself.
