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.
Several of the Group were building NACA foils. But the OzRacer and OzGoose Plans have 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. So some were suggesting using a CNC machine. The discussion goes on to […]
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.
How introductory boats that were intended to be cheap have become crazy expensive. And forced sailing to contract. Hundreds of sailing clubs have disappeared in Australia alone. Sailing is now semi professional and elitist again.
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.
Achieve best Cost/Performance with Traditional Sailing Rigs – Balance, standing lugs and sprit rig sails
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?
Wearing lifejackets and how to get kids to wear them too! Personal Flotation Devices – PFD1, PFD2, PFD3
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!
Many people want to learn how to sail or have done a course in sailing and want to get their own boat. The two best options are below – this page concentrates on the second one! 1/ You can build one of my boats (I know … you were expecting me to say that!). Building […]

FAQ – Building a strip canoe or kayak that can handle some impact in the surf or with rocks. Cedar Paulownia
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?
Dories are a part of the great American Maritime Tradition. From the book and film of Captain’s Courageous to all the folklore about fishermen surviving awful conditions at sea in a Dory.But Do they really stack up to their press? It seems that every few weeks I see a new design for a rowing dory or a sailing dory.
Birdsmouth masts are a really neat method of making a hollow round or elliptical mast. The mast is made of staves which have a 90 degree notch cut out of the stave’s side with a router or using a table saw. For a round mast, identical staves are made up then held together with cable […]
If you understand the plans business as a consumer then you can make best use of the system. A good plans agent will have experience with the types of boat and a large background in helping to solve problems. They may also be able to either supply materials or head you to the best places to get them.
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.
I was writing about this around 2004 when Paulownia first started becoming available from Plantations in Australia. 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 has started to become available in quantity in Australia and many […]
