Over the first few years, new production techniques, such as vacuum bag moulding, were introduced that increased efficiency and allowed more boats to be produced. In 1987 the factory was expanded to 27,000 sq ft (2,500 m 2), by leasing the existing second half of the building and putting in an intervening door. In 1986 six boats were produced.
The boat's design goals were, "a lightweight, trailerable catamaran that was fast, fun to sail, had weekend accommodations for 2 or 3 and was priced below $35,000." The design was intended to reach a break-even point at a production rate of two boats per week and would be profitable at three boats per week. The design challenge was to build a ...
The Alsberg brothers founded their company to build the Express 27, one of the first designs to be built using the vacuum bag moulding process. This boat was intended to compete with designs like the Moore 24 and the Olson 30 as an ultralight racer. Earlier designs in this class had proven fast on reaches and downwind, but did not go well to ...
Then, a vacuum is drawn on the vacuum bag, and atmospheric pressure compresses the part during the cure. When a tube-shaped bag is used, the entire part can be enclosed within the bag. When utilizing sheet bagging materials, the edges of the vacuum bag are sealed against the edges of the mould surface to enclose the part against an air-tight mould.
Kayaks made of fiberglass. Fiberglass composite boats have been made since the early 1940s, [20] and many sailing vessels made after 1950 were built using the fiberglass lay-up process. As of 2022, boats continue to be made with fiberglass, though more advanced techniques such as vacuum bag moulding are used in the construction process. [21]
The J/111 is a recreational keelboat, built predominantly of fiberglass. Construction is glass reinforced polyester and a balsa fiberglass vinylester sandwich via vacuum bag molding . It has a fractional sloop rig with a keel-stepped carbon fiber mast with two sets of swept spreaders , an aluminum boom and steel rod rigging.
The boat was the result of more than 8,000 hours of research and development effort and replaced the Lagoon 57 in production. [10]The Lagoon 570 is a recreational catamaran, built predominantly of vacuum bag molded vinylester fiberglass with a balsa core and teak trim.
The Hunter HC 50 is a recreational keelboat, built predominantly of vacuum bag moulded fiberglass, with a foam-core deck.It has a cutter rig, a raked stem, a walk-through open reverse transom with a swimming platform and folding ladder, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel.
