Motor launch Louise at seven planks
Hampshire-based and Devon-trained boatbuilder Nick Smith has sent us some more photos of his current project, Louise, which he’s currently planking with khaya mahogany. She’s  a 16ft loa, 6ft beam and will draw about 14in.
Here’s what he says:
Louise has seven planks per side now, so thats just over halfway planked up; she’ll have 12 per side when finished. The shape is forming now, and looking fair and well proportioned.

The photo showing me holding a pen illustrates the spiling process  – or ”spoilin”  as they say on the Isle of Wight. A template of thin ply or softwood is clamped to the last fitted plank, by means of  wooden clamps known as gripes, and what you see me doing is running a biro or sharp pencil along the top edge of the plank, thus copying the edge shape to the template (or ‘draw-by’ as we used to call them in South Devon.

The  widths for the new plank need to be transferred from the stem, moulds and transom to the template, giving five points that can be joined up with a flexible batten and drawn along, giving the new plank top edge shape. Because the planks on a clinker boat overlap by a margin (3/4in on this boat) the bottom edge just marked must have that 3/4 inch added to give the full width.

This process is difficult to explain in words but is satisfyingly simple when demonstrated, and is an example of what I call ‘workshop geometry’ .
With all information transferred the draw-by is taken off the boat and ‘spiled off’ onto the treewood awaiting cutting and machining.

Cheers,

Nick’

Thanks Nick! It’s great to see how the process is supposed to work.
Click here for posts mentioning Nick’s previous project, Lisa. If you don’t already know him, Nick comes from Devon and specialises in new builds in clinker and carvel for sail, motor and rowing power from 8ft to 28ft with a special emphasis on West Country style and design, and also takes on repairs and refits from 25ft to 50ft. He can be contacted by email at nick_smith_boatbuilder@yahoo.com and by phone on phone on 07786 693370.

Joe Blathwayt builds a glued clinker dinghy at the Boat Building Academy

Boat Building Academy principal Yvonne Green has sent us a final set of photos from the student launch day down in Lyme back in December, this time showing a 12ft glued clinker stem dinghy built by Joe Blathwayt.

Joe, a former architect, has moved to Lyme and wanted a fun beach and sea angling boat with an outboard, and so he built his dinghy on a course at the Academy.  The lines were taken from a 40-year old 10’ stem dinghy, and then adapted for the new purpose.

Now he’s based at Lyme, I gather Joe plans to combine working on boats and undertaking architectural projects.

Yvonne comments: ‘We started a new 38-week course today. It’s always interesting to see the different mix of people who come to us.

‘We showed them photos of the launch and the boats and told them that’s where they would be 38 weeks from now. The news was greeted with some disbelief… ‘

PS Don’t forget to ask for a pdf copy of the Academy’s prospectus for the coming year, as it makes interesting reading. Email Yvonne at office@boatbuildingacademy.com and I’m sure she’ll send you a copy.

Why use wood to build boats?

Several times now I’ve been promised short articles that answer this question, but as yet no-one has sent me any clear answers – not even those who really should have the information at the top of their heads and have an obvious interest in making the case.

So I was intrigued to find some answers to this question about wooden boatbuilding laid out in a recent post at Tiernan Roe’s weblog Roeboats.  Here are his key points (some are slightly paraphrased):

Where light weight and strength are needed wood is the best material to use.

Pound for pound, wood is stronger than than steel, most fiberglass and aluminium.

On the same basis, wood is stiffer than fiberglass, kevlar or steel.

Wood absorbs vibrations and this includes sound, so wooden boats are quieter.

Wood does not fatigue with repeated loading.

Wood is a renewable resource and the growing of wood removes carbon dioxide from the atmosphere.

Wood is eco friendly in that it can be recycled, fiberglass cannot.

Wood looks good.

Wood allows economical, in both materials and cost, custom production of boats.

Wooden boats require similar maintenance to fiberglass boats. Gel coat is not the wonder material it was thought to be.

Tiernan adds that the reason most boats for sale today are made of fiberglass is that they can be made by semiskilled and unskilled workers who are cheaper to hire than the skilled craftspeople needed to build a wooden boat.

I’d add a couple of points to Tiernan’s list. One is that traditional wooden boats bring so much to the landscape – there are many precious places in the UK that would be utterly changed without their characteristic wooden boats – including The Broads, the River Thames, the creeks of the East Coast, and the beaches at Cromer and Hastings.

Another is that when we build in wood or commission others to do so, we are helping to maintain an important tradition. Boatbuilders teach each other, and the skills have long been conveyed by oral transmission. To my mind, this makes boatbuilding a culturally important tradition.

But although I’m obviously an enthusiast for wooden boats and boatbuilding, I’m sure the cause of the wooden boat is best served by a realistic view of the issues, and that many readers of this weblog will have different perspectives based on their own exeriences.

For example, I’m not sure the maintenance argument is entirely justified. I’ve learned that anything in the open air that is covered with gelcoat or a epoxy and a two-part paint requires far less maintenance than anything wooden that’s covered with alkyd paints, varnish or even teak oils. With our busy working and family lives I have no hesitation in saying that we own and use at least one boat that we wouldn’t be able to keep up it on a DIY basis if it was made from wood.

I wonder also whether the argument that building from wood is environmentally friendly has really been made. I’m inclined to believe in global warming and the trouble it is bringing, but I feel also that the arithmetic we presume when we’re making judgements about environmental issues is often overly simplistic. For example, when wood eventually rots its breakdown must release carbon dioxide and the much worse global warming gas methane. So what is the lifetime cost of a wooden boat to the environment compared with a plastic one? I haven’t a clue, but I don’t think the answer should be taken as obvious until someone clever works it through and provides us with the result of their calculations. Just to add a factor that seems relevant, what is the contribution to global warming made by the drying of spirit-based paints and varnish?

These are just a few thoughts of mine.What do you think? Are there any points here you’d argue with? Are there any arguments to add? Comments via the comment link below and at Tiernan’s weblog please!

PS Fans of the US designer John Atkin will be interested to know that Tiernan is currently weblogging the build of a clinker-built Atkin Ninigret.

PPS I’d draw your attention to some of the comments below, particularly those of West Country boat designer, occasional building and general sailing man John Hesp.
