Why Plywood breaks – Real wood for Centreboards and Rudders
One recurring problem with plywood foils, centreboards, leeboards and rudders is that over time they tend to break unexpectedly.

Make excellent and accurate foils (centreboard, leeboard, keel or rudder blade) adding way more performance for not much effort and no cost – series
When a boat owner considers upgrading their boat to make it safer and get more performance, often the first thought is for new sails which is expensive, but a cheap hack is to improve the foils (centreboard or leeboard) which might take little more than a couple of weekends and cost around 50 bucks.
Owner: I am not much interested in racing, but there is no motor mount on this boat, and there never will be. I hate rowing, so the boat has to be able to take me where I want to go under sail. The foils were the first step-this sail completes the journey. :)
How do you rig your Goat Island Skiff or other balance lug rigged boat? This page will be useful for everyone, but specifically assist Goat owners in selection of rope, rope lengths and show all the rigging details. We have also found a number of cheaper ways of doing things from our experience in the Philippines. Halyard, downhaul, outhaul, lashings, rope fittings, rudders, centreboard.
A good centreboard or leeboard is as important as a good sail. We use a simple templates for quick and accurate shaping. Making without the templates … several were feeling that they couldn’t make them to a greater accuracy than 1/16th of an inch.
A discussion about basic pros and cons for swinging centreboards. And dagger centreboards. Centre Board means the board is in the centre. Which is different from a Lee board which is too the side.
Racing shows that what you know is what you know. It doesn’t matter if the boat is less than perfect. So where is it best to put in the effort to improve results. Boat setup, knowing how to adjust for different wind conditions, practicing skills until they become automatic, sailing as much as possible … and teaching others.
Mark Milam has done an amazing job of overseeing a project combining his work with that of a boatbuilder friend. Also the best method I have seen of supporting a windsurfer mast in a sailing dinghy.
Wonderful woods, some great detail design and the very best fitting of a windsurfer rig to a dinghy that I have ever seen.
The conservative viewpoint is that traditional rigs are not very efficient. However allied to efficient hulls and set up correctly, lug and sprit rigs can be very efficient indeed – not too much slower than “modern” rigs, particularly when the same lessons are applied to trad sails and way cheaper.
This is a WIKI drawn from the group on the Storerboats forum discussions on setting up lug and sprit rigs for best performance building on the information in my webpage.
Bruce in New South Wales, Australia has launched his Goat Island Skiff plywood sailing dinghy at Port Stephens.
They had a nice day sailing around but capsized the boat by accident when someone tripped up. Ooops.
I am still not sure who is to blame!
We are still waiting for launch day pics to be retrieved from the waterlogged camera.
This podcast/mp3 talks about why Australian (and New Zealand) wooden boatbuilding is different from the rest of the world..
Click to listen to the talk. This is the third of three.
This talk is the first hour of my exposition on boat building and design. There are two more parts to come. This covers some of the background and design issues. The second is more on the building side and the last is a bit more about why the Australian (and New Zealand) wooden boat tradition is different from the Northern Hemisphere.

This is a basic section on the stages of fibreglassing areas on a plywood boat, canoe or SUP. Many problems can be avoided by being methodical and setting up each stage carefully rather than rushing in.
