Many methods have been tried but this one successfully used by Russ Stevenson works well This is the second smallest of his Spray series and the larger of the two trailerable ones. A multi-chine plywood design, the cutter can be built with either marconi or gaff rigs and in either pilot house or conventional sailboat configuration. Luckily, decisions on those two matters need not be made Wood Boat Plans Pdf Writer until bulkheads are installed, so I have a while yet to decide.

I made two modifications. First, the Sprays have a conventional transom which turns to vertical for the upper one foot. I kept the taper of the transom all the way aft, which will increase cockpit or lazarette space and overall length to about 28'. The shape is more pleasing to my eye. Secondly, I am building the hull with a modified stitch-and-glue or, more accurately, epoxy chine method.

The hull is roughed in and when fibreglasses will be turned over with the temporary frames still supporting it. At that point the fillets of filled epoxy will be installed inside as the chines.

This modification was done with the blessings of Mr. Roberts himself, incidentally. This ballast box, still empty, was fitted into place and the wooden keel laminated up around it.

Then I removed it to be bolted in position later with the hull upright. I also located an old-but-good Yanmar 8h. A stern view of the hull, now covered with 6 oz. Much sanding and fairing remains before it will be ready for paint. To turn the hull we had, naturally, a party. This is experience over thousands of boats with information shared by various class organisations. Over the couple of hundred boats I still know about and the thousands I kept track of for some time — the difference between epoxied and non epoxied boats is chalk and cheese.

Can an amateur do a good enough job with epoxy to get the low maintenance and longevity? Now 20 years later all the boats I am still in contact with are going very nicely in good condition and less maintenance. Two pot polyurethane paint over hulls is still immaculate. I felt that epoxy was too expensive and a bit weird in the early days designing and building boats so my original BETH design 1 was cut up last year — the paint and varnish no epoxy had failed to protect the boat — the outside was a real mess of cracking veneers.

She was outside but under a good cover … just the same as the Goat Island Skiffs in the para above. If a quality epoxy no thinners and applied properly by a caring amateur builder as a starting standard it is very effective. Like I said, I started off pretty well in the non epoxy plywood dinghy building days in Australia.

Then I was grudgingly converted to epoxy by working with so many boats and customers and seeing it really worked compared to the previous alternatives. At one point I would have pretty well said that building of anything that is not epoxy is a waste of time.

For gluing alone of our size of boat, epoxy is still in there because of its gap filling properties. It does make a much more fail safe option.

Failures are interesting. They are strongly statistical in nature, which is why I dwell on big numbers of boats … broad experience. Like hydrofoiling moths … Theres Outdoor Chair Woodworking Plans Co Ltd a few odd hydrofoil boats every decade that perform in one direction only or are expensive, but it took Australian Foiling Moths racing every weekend and once of twice through the week to make it truly feasible in all directions at reasonable cost at least initially.

Now they can takeoff in about 5 or 6 knots or supernaturally keep foilborne in 2 or 3 knots of breeze if they are up already. Week by week, numbers and sharing information. Florida builder and designer Paul Ricelli is a big favourite of mine — he knows more about alternative materials than anyone. So … how do I know polyester resin is inferior? Sometimes it will stick like Hades, other times you can tease up a corner and pull a whole sheet off a deck.

Sometimes you have sticking and non sticking in the one job! Back in the days when I was involved in PDRacers a couple of serial builders found that the real costs of using epoxy as the glue only. The costs are very competitive with the real costs of alternatives. Down to the big box store, get the bits and start the same day. From that point of view, even polyester has some positive points.

The other reason is a bit mythic, but it is real. The limitations of alternative glues close fits, high clamping pressures and some limitations in waterproofness. But in reality they engender a much more carefree approach. This is maybe not so good for the longevity of the build, but it does engender a cheerful attitude of enjoying the building. Squirt some goo out of the bottle and screw away.

People get really excited about it. Compare with the early paragraph I wrote in the previous missal about the stickiness of epoxy and the strongly procedure based work and the somewhat different feeling.

Real Marine ply is not that much more expensive. Timber prices similarly — most of our woods are hardwoods and lighter timber for home boatbuilding is often imported. Look at prices about 5 to 8 times what you are paying in the USA.

So you have a larger initial investment. Poorer ply just falls apart and there are two or three brands of good local ply. You might be looking at 15 dollars a sheet.

But a middle ranking office worker gets a quarter or less of the income of someone in the USA or Oz so ply is effectively four or many more times more expensive depending on your income.

So again epoxy is usually used. Epoxy is actually somewhat cheaper here because of bulk imports from China, same with glass. All epoxies come in two parts, the resin and a hardener curing agent.

Mixing ratios will vary from one product to the next. There are numerous epoxy resin thickeners which are available commercially, such as micro balloons, talc, silica and the like. I have heard of pulverised limestone and Portland cement being used successfully, however these must be a bugger to sand.

A layer of fiberglass cloth is used to add a high degree of protection, Wood Epoxy Boat Plans Growth strength, abrasion and impact resistance. There are a number of different forms. Tips on Applying Glass Cloth. There are some specialist epoxy resin coatings which can be applied to damp and saturated surfaces and even underwater.

Entropy Resins are made using a plant-based epoxy called "Super Sap" instead of petroleum based products. Environmental benefits include bio-based content sources and a reduced carbon footprint. It's relatively low viscosity and great adhesion to all substrates makes it an excellent composite laminating resin.
