$@# Fiberglass Boat Building And DIY Guide &^@!

Boat building in fiberglass news letter boat plans for boat building To build one fiberglass boat, it is often said, you must in fact build two boats: the finished product and the mold from which it springs. With a female mold, you normally build three boats to get one--first a male plug on which the female mold is formed, then the mold, and finally the boat itself. Mar 08, �� Dufour Yachts walks us through the process that goes into building a fiberglass hull, from the mold, to the fiberglass hull that's ready for finishing. March 8, Boat construction always starts with a hull mold. In this case, a perfectly clean, highly polished two-piece mold to ensure no imperfections make it into the final composite. Fiberglass boat construction became popular in the s and today is perhaps the most common way production boats are built. Upsides to this method include relatively low maintenance, high strength, ease of repair, and generally low cost when compared to other boatbuilding materials.

This serves both to reduce stress in the area and to strengthen the bond generally, as the transition from one bonded surface to the other is more gradual. The wider the radiused angle, the stronger the bond will be and the less stress it will experience. Properly installing an interior hull structure can be very labor intensive. This is probably the one phase of boat construction where builders have tried hardest to streamline their procedures.

The larger the part, the bigger the savings in terms of work and effort. A truly comprehensive one-piece hull liner can include not only a structural bilge grid, but also all major furniture components from the bow to the stern. Bulkheads and partitions in these cases are not bonded directly to the hull, but are fitted and glued into pre-molded slots in the hull liner and overhead deck liner or, alternatively, are bolted to special flanges in the liner.

This relatively light bond should then be improved by tabbing the liner to the hull with glass tape anywhere there is access to contact points between the two parts. Such access, however, is always limited, and work spaces are often cramped and awkwardly situated. In the end, it is never possible to create as strong a structure as is formed when all individual components are bonded piece by piece directly to the hull.

If the hull is unduly stressed, the liner may break free in some areas. I have heard more than one tale of mass-produced boats failing like this in strong weather. Such damage can be difficult to detect and is always difficult to repair. It may involve cutting away and then rebuilding large portions of the liner in situ, which may prompt an underwriter to declare the boat a total loss.

The best practice is to create the hull liner in small sections and install the parts separately. Ideally, support for the bottom of the hull, usually a grid of some kind, is laid in first. One-piece grid pans are often used, but it is best if the grid is built up in place with each part bonded directly to the hull.

Bulkheads and hopefully partitions should also be bonded directly to the hull. Separate interior liner sections can then be laid in place around the bulkheads and on top of the grid. It is easier to create strong bonds between the hull and these smaller, more discrete parts; the bulkheads and bilge structure will also both offer more support to the hull than would otherwise be the case.

Another disadvantage to a hull liner, no matter how it is installed, is that it limits or precludes access to the hull once it is in place. This makes it hard or impossible to repair damage to the hull from within the boat without first cutting away the liner. If the hull is breached while underway, a liner makes it harder to both find and staunch any leak, which is why some cautious cruisers always carry a heavy tool such as an ax or crowbar for quickly tearing away a liner in an emergency.

I had a feeling there would be issues with bonding to the hull �onwards � more importantly � must look at engine Fiberglass Boat Building Steps Up mountings before engine arrives, thanks again, S xxx.

Charles Doane December 5, Fiberglass Boat Building Steps Key Since the advent of fiberglass, however, boatbuilding has increasingly become an industrial process as opposed to a craft. The biggest builders these days can churn out hundreds--or even thousands--of boats a year on massive assembly lines studded with computer-controlled robots that do everything from spraying gelcoat into molds, to cutting hatches and drilling holes for fasteners in decks, to cutting, trimming, and even varnishing interior woodwork.

But even on the most automated production line, a lot of manual labor is still needed for a boat to be built properly. Given the relatively small market for new sailboats, there is also a surprisingly large number of small builders who still build only limited numbers of boats using little automated machinery.

For many in the industry boatbuilding is primarily a labor of love; to them boatbuilding will always be an avocation and never just a business. Generally, however, the Fiberglass Boat Building Steps 20 companies with the best long-term chances of survival are those that focus on economic reality and production efficiency. One thing many mass-production builders have come to realize is that their biggest competition is not other builders of new boats, but the ever-growing number of older glass boats that are still on the water.

It is now 60 years or so since the first glass boats appeared on the market, and there is still no evidence of any inherent limit to their useful life spans. As far as we know, a well-built, carefully maintained glass boat can last virtually indefinitely. This, unfortunately, only encourages builders to produce boats that are less than durable. Buyers who expect to trade in or sell a new boat within a few years need not worry about this, as serious maintenance issues are unlikely to arise in the first few years of ownership.

To help those who find their cruising sailboats on the brokerage market i.
