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.

The talk does discuss the sizes of normal boatbuilding joints and how I generally think scarf joining plywood is a waste of effort (unless you like that sort of thing!)

This diagram will make some of the talk more clear. It shows how all plywood joint sizes evolve from the plywood thickness and are simple multiples of that thickness (“t” in the diagram). If two different thicknesses of ply are used they only need to be the right size for the thinner ply.

Note that the epoxy fillet is made with a high strength gluing additive – not a low density powder.

These are for plywood joins only.  If doing timber scarfs for spars and other high strength applications then the scarfs usually need to be 8 times the thickness of the timber.

Also the fillets have a limitation that as the boat gets bigger they become too big and expensive and it becomes cheaper to either do them in timber or make smaller fillets and glass them with biaxial glass.

Making plywood joints bigger than what is specified above is a waste of materials and labour and makes the boat heavier than it needs to be.

Anyway … cut to the chase again – this talk is about 40 minutes and is the second of the three. Click on the play arrow or download below

On the "round Australia trip" I found myself employed by a tiny business in Adelaide - Duck Flat Wooden Boats in Adelaide.It was an eye opener - It became clear that one could build a boat for a fraction of the cost of current racing boats.My ideas hinged around high performance, easy building, fun to sail and reasonably cheapToday Storer Boats are built in all countries and we have active groups on Facebook for the following groupsGoat Island Skiff Open Goose Storer Boat plans Really Simple Sails

  1. Thanx Michael! … your my hero ..[sorry Geo. Buehler] .. there is A LOT to absorb .. trying to rethink and adjust.. to building lite .. but maintain extreme integrity .. a skipper has to trust his boat. The Gulf of Mexico takes no prisoners .. this section answers my immediate questions ..

  2. Thanks Paul … I try to put in a lot of different information in all my lectures. There is such a diversity of information and method that is not often reflected on the net.

    The thing that drives me is that there is a gap of perception between cheap and simple boats and good performance.

    Along with a few others I think this gap is a myth. Racers are wrong that performance costs money and the cruisers are wrong that performance is troublesome in some way.

    Thanks for the nice comment.

  3. […] I just have the link in my clipboard … so here are common epoxy/ply boatbuilding joints There is a good argument for using timber in the corners to join the ply along with the […]
