A whole bunch of strategies for lightweighting a plywood stitch and glue canoe. In this case a Storer Boat Plans Eureka Canoe. Standard build is around 44lbs. Ten lbs were saved to bring the weight down to 34 or 15k
Planing and downwind speed is a practiced skill. But the 8ft OzRacer and the 12ft OzGoose have strikingly different behavour. Goose planes easily in light wind. OzRacer needs a lot more wind and jumps up and down in speed.
Sailing too fast upwind in a non trapeze dinghy means you lose a lot of pointing angle. So what is the correct compromise between high and slow and low and fast. Explanation involves the increase of drag around hullspeed.
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.
Making a boat light may make the hull distort more thus losing some of the advantage. But is is possible to build light without distortion. The answer is YES.
The Oz Racer led to the Oz Goose. There was discussion about whether the OzRacer would plane and just how light it would be possible to build. Extrapolating from the Moth Scows in Australia I made a guess.
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.
A guide for choosing cheaper alternative rigs. Balance Lug, Standing Lug, Sprit, Lateen and more. These rigs typically save a lot of money over conventional sailplans and set up right offer much the same performance. They respond to the same principles. Are boomless sails OK?
Three times in my life I have gone sailing in small boats without a lifejacket. Two times the boat sank. One time I capsized and found that swimming and trying to get back on the boat is very difficult in FRESH water. Also a hint about how to get kids to wear their lifejackets … wear YOURS!
If you want to go sailing what is the best way to get a sailing dinghy? Maybe build but most will buy a sail boat secondhand. How do you pick a good used sailing boat? We show you how.

IMPACT! How hard is your boat going to hit something. For most of us it won’t be very hard at all. So it is better to save weight. For expeditioners they may require a lot more from their boats. What are the strategies one can think about?
A birdsmouth mast is a nice way to make a simple tapered hollow round mast. But what is the best way to join the wood. We show you how and why.
Building boats from older plans often adds a lot of labour and materials cost. Some old plans are great. But many are utter rubbish. Having a living designer or other people building the same boat is really useful for most builders.
We first started to see Paulownia becoming available from Plantations in Australia around 2004. Well before the current boom in its use for framing and hulls of dinghies, yachts and other boats. Paulownia is a very lightweight timber from China that provides one way of building lightweight boards and boats. How to overcome its weaknesses and make use of its strengths.
Never join boat decks the way you join up panels in a house. Cracks and big failures will result.

The dominant source of timber sizings or scantlings for traditionally built workboats in Australia is the USL Code. It would probably be OK for traditionally built workboats in other parts of the world. It has information for both traditionally planked or semi traditional plywood boats of larger sizes
Oil or diesel fuel have soaked into some of the areas you want to work on. There are no easy solutions. But this one might work.
OK … I decided to keep the old racing dinghy and fix it up. How do I put my effort in the right places to get the maximum results? A grab bag of methods for joining plywood, working out sizes, making centreboards and rudders and more.
