[ What is claimed:] [1.] A process for the preparation of boat hulls having one or more fiber layers that can be used to combine with other photocurable structures without forming bond lines, said process comprises the steps of:A. enclosing at least one reinforcing fiber mat or fabric within an ultraviolet radiation transparent conformable and textured vacuum film forming an upper layer and a lower substrate to form a vacuum chamber, said film permitting transmission of ultraviolet radiation and flow of gases and resin around said mat or fabric, said chamber having at least one vacuum port and at least one resin supply port;B. evacuating said vacuum chamber and introducing a flow of a photocurable resin so as to form a rein impregnated layer or layers of reinforcement; and thenC. partially photocuring said resin impregnated layer or layers whereby said partially cured layer or layers are capable of being bonded to other photocurable structures without forming bond lines.
