Viola 14 Canoe - Joost sailing upwind - boat planArticles discussing my thoughts on sources for boat design information for performance, structures or boat handling – with a bias towards repeatable information.

It could be from competitive sailing or through interpretation of careful testing by others including my design peers. It all ends up applying to my boat plans

In the end … if it doesn’t appear on the racecourse somewhere … it probably doesn’t work.

This may be an overstatement, I have a soft spot for those who work through several versions of an idea over time.

Goat Island Skiff going fast downwind with heavy load - Texas 200

Strong wind downwind with unstayed Masts, Cat Ketches and Cat Yawls, more safety and efficiency

John Goodman and I sailed the immaculate Goat Island Skiff he built from my plan in the Texas 200.

The boat showed itself to be one of the faster in the fleet despite loading up such a short boat with food, water and camping gear for six days with little outside support.

We played with sailing the boat by the lee – a method used by racing boats to gain both speed and control.

I document the method here including a video showing how the angle of heel can be controlled using the mainsheet.

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.

Goat Island Skiff in Victoria – Dete Hasse and his boys (and the value of reefing

Dete Hasse and his family built a Goat Island Skiff in Geelong, Victoria a while ago. He has just written to me about his experiences trying to sail on Port Phillip Bay and more happily on the recently refilled (the drought is over!) Lake Eppalock.

Also he makes some good comments about reefing and how it changes an overpowered boat into a much more rriendly beast in stronger winds.

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. These are online and paper resources that force thinking in different ways.

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?

Video of Quick Canoe in Hungary.

A video of the Quick Canoe in action.

My Agent in Hungary who sells plans in both English and Hungarian has launched the first Quick Canoe in those parts. It is designed as a very simple and easy to build boat. It is not a perfect high performance boat, but the numbers have been worked out to give good performance despite the simple shape. It won’t be as good as the best fibreglass canoe, but it will be better than many average ones. And much cheaper and lighter.

WIKI setup and tuning Lug Rigs, Spar bends and weights, Sail controls and More

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.

Setting up for performance – Balance Lug – Goat Island Skiff

John Goodman who recently spent 5 days semi racing a Goat Island Skiff in the Texas200 event got back to me with some observations and even some pictures of aspects of the boat and the sailing.

I have responded with suggestions to make some further improvements. Between John and me there are some useful tips about setting up a boat for more speed.

However the standard setup of the Goat is fine for most – it is still pretty quick in standard form.

There is advice for both lug and sprit traditional rigs here.

PJ and Cliff show how to build a plywood Quick Canoe 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.

Light outriggers to add to your canoe for stability. Fast sailing, Fishing or Diving Philippines: storerboatplans.com

Drop in Outriggers – photo and comments from the Philippines

Finally after many years of selling the plan I have a photo of a boat with the outriggers from the drop-in outrigger plan.

Every part of the outrigger is very light. The first one we built had each component under 10lbs.

It can make a canoe or kayak into a killer sailing boat. Or can convert a canoe, kayak or suitable dinghy into a stable fishing or diving platform for paddle or outboard.

Quick Canoe assembly – Woodworker builds in 4.5 hours (I took 2 weekends)

Fast building was part of the aim of this plan! Also to keep the expense down. Rick surprised me – I was thinking it would take a couple of weekends. The Quick canoe is very simple to build and comes out of three plywood sheets. A very simple plywood canoe 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.
