Book – “A lighter ton” – New Zealand racing yacht design in the 1970s

In the late 70s as a sailing teenager I drew boats on every available paper surface. A new book “a lighter ton” describes the exciting development of racing yachts to create newer, lighter, faster and cheaper and FUNNER boats. Many of the developments were from New Zealand designers such as Bruce Farr, Paul Whiting and Laurie Davidson. A new book by Richard Blakey covers this exciting experimental period in yacht design

Fast building two plywood Quick Canoes in one week to paddle touring the Loire River in France – Part 1

The above photo was taken on the third day of our Canoeing trip on the Loire River in France. The two black canoes didn’t even exist a week ago. When I wrote the original article on Disposable Canoeing I had no idea at all what it would lead to me and a bunch of adventurers, wine and cheese connoisseurs. Most of us didn’t even know each other! The picture above is the result of this adventurism, but what happened to make it happen? What technology was involved to make the boats faster to build than most stitch and glue boats and what weather conditions did we have to overcome to make it all happen.

How much fiberglass will prevent most damage to my ply or timber canoe or sailing dinghy?

How much fibreglass is really necessary to prevent damage to a plywood boat for most users? For a long time I’ve been suspicious that both designers and builders are in a never ending spiral of more and more heavier fibreglass. I argue, with data from the Turner designed Jarcat, that the weights of glass are clearly excessive for most uses and users of small boats.

The Canon – Tools for thinking about sailing and boat design – Books and Articles

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.

Rules of thumb for boat and yacht design – are they legitimate?

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?

PJ and Cliff build a plywood Quick Canoe for the Tinaroo Raid in one week

Cliff and PJ live in Warm Queensland and Wintry Tasmania. However they both like to go the the yearly (June) wooden boat festival in tropical Far North Queensland. This year they decided to build one of my Quick Canoes. They started on Saturday and finished including putting the canoe on the car roof by the following thursday. They are experienced woodworkers so added some very nice details.

Minimal repairs to keep an old Mirror plywood sailing dinghy going

Melanie in the UK wrote to me. She has just bought an old Mirror dinghy and started sailing for the first time. Problem is that the boat leaks and she doesn’t want to stop using the boat until the end of the season. I have a philosophy of keeping older boats on the water and not pulling them off for months on end until you have the time to do the job. So the article here is useful to see what can be done with an old leaky plywood sailing dinghy to keep it going. It is perfect sailing weather at the moment in the UK and it is better she is out there learning but with the worst of the leaks gone. With a disciplined approach she should be able to get all of this done in a week or so. The general leaks fixed permanently and the rotted area reinforced so that the boat won’t break.

New plywood canoe plan builds in 4.5 hours.

The plywood “disposable” canoe (see here) has been renamed the more salubrious “Quick Canoe”. I quite liked the name of “Disposable Canoe” but I agreed with the critique that it hinted at something that was poor quality rather than simple and Easy. It has been designed to be as easy to build as possible while keeping some of the qualities of a good paddling canoe – in particular the ability to track.

MSD Rowboat in Brisbane. Built by Tom

Tom has built his MSD Rowboat in Brisbane. I met up with him recently and we drove down to the coast towing the rowboat to the river at Nudgee. A bit of wind and a lot of current because of all the rain. Tom has trimmed down the skeg to get the boat to balance nicely in all directions. Before the modification the bow used to blow around – now it behaves nicely. I took quite a few pictures.
