The Moth Dinghy developed foiling to near perfection through two decades of information sharing and weekly racing amongst an international group of backyard tinkerers. The Moth will lift up in 4 knots of wind, once up it can sustain flight in two knots. Meanwhile the America’s Cup boats cancel racing in 10 knots of wind because they know their boats are boring below that speed. This also means the America’s Cup boats cannot really improve foiling performance to be full range. Weekly racing in all conditions is the key.
Fibreglassing 3 – bigger areas – centreboards, rudders, leeboards, keels and larger hull areas requires a different method. Normally glass is draped dry over a clean dry surface and epoxy is applied to the outside and pushed in through the weave.
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.
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.
Why are these plans FREE? Because I want people to know just how good correctly proportioned touring paddles can be. Most of the paddles sold commercially are based heavily on racing models, which are fine if you are in training and only want to go 500 metres at the highest possible speed. For the rest of us there is a better balance available when we might be paddling for several hours or where the boat may be loaded. The oars were drawn to fit the Goat Island Skiff, but will fit other boats of a similar width.
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.
BETH sailing canoe is design #1. Light enough to cartop and at home in a club fleet of lasers. Much easier and lighter to set up and sail than a Laser. Really only recommended to experienced dinghy sailors.
This is a reprint of an article from the OzGoose website with a preamble by me and some reorganisation to make it more useful to owners of other boats. As you may now we are one of the main developers of the knowledgebase for lug rigs, setup, rigging, control and performance. See the list of […]
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.
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?
There are two versions of the OzRacer and one Kit for family sailing, learning to sail or club racing. The Kit by J.O. Woodworks fits the PDRacer rules but carries just about all the OzRacer advantages of Performance, Lightness, Ease of building and that you can build the boat very cheaply and still get first class performance. The plans even show you how to make a proper sail from polytarp at home. All for $20!
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
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.
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.
The GIS excels at a competive row and sail event. The Caledonia RAID is one of the oldest events of its type. A competitive multi day event that crosses Scotland from West to East including a crossing of Loch Lomond. It tends to attract long and efficient rowing sailing hulls. And here was one of the shortest, simplest and lightest hulls in the fleet punching well above its weight
We have moved much of our activity to the Facebook Groups. See the links in the Menu above. But there are so many great questions asked and discussed on the Oz Woodwork Forums..
A sharp eyed customer notified me that I hadn’t included a method to right the OzRacer RV. The nice thing about the OZ series is that all the boats come up with very little water inside when righted from capsize. Also the wooden mast doesn’t allow the boat to turn completely upside down making righting […]
