How to Lightweight – Balsa Canoe strip planked 12lbs (5.5Kg)

A 12lb canoe. The idea was to build a Rushton Wee Lassie in balsa strip with very light glass. The boat ended up being fairly durable despite not being interested in durability. As far as I was concerned I was going to be happy if it lasted a couple of years before being chucked into a dumpster somewhere. But five years later it was still beautiful despite good use.

FAQ – Paulownia or Kirri – the “newest” lightweight timber for Boatbuilding.

We first started to see Paulownia becoming available from Plantations in Australia around 2004. 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 provides one way of building lightweight boards and boats. How to overcome its weaknesses and make use of its strengths.

Philippines Dugout Canoes for rapids and rocks – Pagsanjan Falls

I am in the Philippines at the moment.

I took five days out to go to the area where one of my Australian Filipino friends has her hometown. The general area is Laguna, I was staying at Lumban and nearby was a canoe trip to Pagsanjan falls.

I was really interested to see the local boats and to see how they might relate to the timber boats that existed previously. The boats are elegant and very well suited to their environment. Paddling and motor canoes are used on a daily basis.

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. 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.

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.

Podcast Online – Wooden Boat Construction by Michael Storer – 2 of 3

This is the second of my talks in the USA. It focuses a bit more on construction and some of the methods that can be used to keep a boat light and simple, but very strong and stiff.

It also discusses how there is a “creep” in boatbuilding and design that increases the weight of boats way over what is really needed for a strong structure.
