A Fenwick Williams catboat carefully reinterpreted in Cedar Strip. Includes cleaner structure, optimised foils and a tabernacle rig that allows raising of the mast by one person. Built by David Wilson at Duck Flat Wooden Boats in Adelaide.
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.
[Translate] 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 […]
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.
OK … it IS a rant. But it was prompted by the very legitimate question about why have a mizzen sail.But sadly I descend into a rant about how expense is a really poor predictor of performance.
The OzRacer RV sailboat is meant to be a very simple boat that can be homebuilt.Most build it to get on the water quickly, but Mark Milam has done an amazing job of overseeing a project combining his work with that of a boatbuilder friend.Wonderful woods, some great detail design and the very best fitting of a windsurfer rig to a dinghy that I have ever seen.
Joe sent me a question about why his self designed sailing rig for my Electric Quick Canoe design works better if he moves the leeboard forward of the theoretical point for a balanced helm.He has stumbled upon a nice observation of a design element called “lead” (I lead you … not the metal Lead).I explain
[Translate] Finally I finished the plan for the new OzRacer RV. It is a much simpler build of the original OzRacer concept so will be very attractive to people looking for a first boat. Plans are still the old $20 but even more detail than before. Order the plans for the simple and cheap OzRacer […]
The OzRacer Mk3 has been rebranded as the OzRacer RV.Detailed plan – a boatbuilding course in a book for $20 each.So now racing sailors can use the OzRacer Mk2 and cruising sailors can use the OzRacer RV plan. The RV is no slouch though – it won the World titles in 2010.
The rudderbox design I use has distinct advantages over normal swinging rudder setups. Once you try this design you will never be satisfied with a swinging blade again. But some of the details are important!
Golfballs go further because of those dimples on the surface. Would it make sense to have those dimples on a boat hull?It is not quite that simple as this little article attempts to explain.
One of the most important things as a designer or sailor is to keep an open mind, but also to be able to analyze things in light of real experience and prior knowledge.This article, after a bit of a spiel, goes on to give some great resources that “opened my eyes” at different times in my life.They focus on areas of structural design, sailing, sail aerodynamics and touch on a bit more.
There are lots of tips for building and designing boats on the net.“Rules of thumb” are often quoted to help with the calculation of how much sail or how much keel or centreboard area or how big a mast is allowed to be and many other areas. Can a boat be stretched or shrunk or lengthened?But how correct are they? Are they the best guide?
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.
Reprint of an article I wrote a few years ago for Watercraft magazine in the UK.The article points out why I think most of the discussion about boat design being a “compromise” is rubbish and taking that point of view means that the design is sure to be compromised.What happens if we don’t accept the compromise?
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.
The discussion on this topic went on.Dave asked if people would laugh if they saw a PDR sailing in company with something more conventionally shaped.Luckily I had a video clip to hand.
