Repair, Tools & Materials

The ultimate in trivial significance is probably Richard III's lament about losing a battle for lack of a nail. By contrast, use a nail in a fiberglass boat and it's likely the boat will be lost. Nails as well as wood screws have little application on a modern boat. The reason is simple: almost any fastener will do a better job than either. In this day and age the most practical fastener material is stainless…

We don't really know what the life expectancy of a fiberglass boat may be. There are lots of them out there that are more than 20 years old, still going strong. We do know, however, that no matter how longlived fiberglass may be as a structural material, over time the gelcoat sur­face commonly used in finishing fiberglass becomes porous and chalky, and has the unfortunate tendency to crack and craze. Gelcoat, in other words, weathers just as a painted surface will over time. With topsides, a tired gelcoat surface can be restored to better than new condition through the use of polyurethane paints, which can retain color and gloss for years. Decks, however, are another story.

Practical Sailor contributor and world cruiser Joe Minick details the steps he and his wife took to replace the wornout teak deck aboard their Mason 43, Southern Cross. Minick breaks down the major tasks of the three-month project and explains how they saved a lot of money by doing some of the work themselves. The article looks at the pros and cons of a do-it-yourself teak deck refit; planning and budgeting; step-by-step removal of hardware and the old deck; and the detailed installation process of the new deck.

Do you have any suggestions on a book or manual that explains how to replace a cored deck where most of it is soaking wet? I replaced a 1.5-square-foot area and was surprised to see that it was so wet and rotten that I could grab the wood core and squeeze it like a sponge.

There was a time when laid decks — teak, yellow pine, or fir — were the hallmark of a true yacht. The bare wood gave secure footing, easy maintenance, and reasonable protection from leaks. Since the advent of fiberglass, those same laid decks, almost universally of teak, have con­tinued to represent that hallmark. However, they have become at least as much a cosmetic feature as a functional one. Teak decks, cockpit seats, cockpit sole, hatchtops, and cabin sole all lend themselves to being planked (or sheath­ed) in a traditional manner Almost no project can do more to "dress up" a boat than some laid decking, and it is a job the average boatowner can do himself. This article describes a simple method for laying decking, one we have used ourselves.

It takes practice to produce a perfect, mirror finish on var­nished wood, but it is not so much a difficult task as an exacting one, where attention to detail and no short cuts are the secrets to success. Whether you are finishing new wood, refinishing old wood, or maintaining a finish in good condition, the basics are the same. Tools and materials required are sandpaper, vacuum cleaner or dusting brush, tack rag, brushes, and of course varnish and thinner If you are working from bare wood you may require stain or filler or a combination filler-stain. In cases where old wood has become discolored you will probably want to use a bleaching agent.

Improperly mounted stanchion and pulpit bases are a major cause of gelcoat cracks in the deck radiating from the attached hardware. The cracks are usually the result of un­equally stressed mounting fastenings or inadequate underdeck distribution of hardware loads. Frequently, a boat is received from the builder with local cracks already developed. Once the deck gets dirty enough, these minute cracks start to show up as tiny spider webs slightly darker than the surrounding deck gelcoat While repairing these cracks is a fairly difficult cosmetic fix, the underlying problem — poor mount­ing — is fairly easy to correct in most cases.

There are three basic types of transparent plastics used on boats: clear vinyls, acrylics (the best known is Plexiglas), and polycarbonates (the marine standard is Lexan). Each has advantages and disadvantages, which is why most boats include some of each. Vinyl is actually plasticized, stabilized polyvinyl chloride (PVC). It’s the plastic of choice for any window or clear screen that rolls, folds, stretches or needs to be sewn to fabrics.

Earlier this year, reader and occasional contributor Fred Hatch found himself facing a quandary common among boat owners. The topsides of his 32-foot sloop were well faded, and small blisters were beginning to show along the waterline. Would he be in for an ambitious haulout and big yard fees, or might there be other remedies?
