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.

Ella, a 12ft stitch-and-glue skiff

Preliminary drawings for the Ella skiff

I’ve decided to develop plans for a little 12ft stitch and glue skiff using Greg Carlson’s excellent Chine Hull Developer plywood hull development tool (scroll to near the bottom of this page).

This small project will take a little while to complete, and follows my 15ft 6in stitch and glue Julie skiff, which has attracted a lot of interest. However, boats like the the Julie can easily be a bit too much of a project for many people: they’re too long to be built easily in the average garage (in the UK at least), and they’re marginal when it comes to car-topping.

So these preliminary drawings show the very beginnings of the 12ft small skiff, which I’ve chosen to name after my daughter Ella. It will bear some similarities and of course quite a few differences compared with the larger boat, not least because the lines of a short boat like this must be rather fuller than those of the larger model and can’t benefit from the same hull form features aimed at reducing drag due to the formation of eddies.

However, like the Julie skiff, it has been conceived with rowing, not outboarding or sailing primarily in mind. For those who take an interest in figures, ratios and the rest, the wetted area here is 31sqft, maximum beam at the gunwales is 4ft, the design displacement is 400lbs, the righting moment is 254ft-lbs at 15 degrees of heel, and the prismatic coefficient is about .57.

Anyway, I’d be delighted to hear from people interested in the project – you can reach me at gmatkin@gmail.com.

PS I made a train journey this pm and took the opportunity to make a bit more progress. I’ve made up a lines drawing, and sketched some internal joinery, including what will be a removable centre thwart to allow the rower to row from a forward position when there’s something or someone heavy in the stern.

Three score and ten – the greatest fishing disaster ballad

the_storm_engraving_by_william_miller_after_van_de_velde-470

The chilling engraving The Storm by William Miller after Van de Velde,
published in 1858, taken from the Wikimedia. They’re not English East Coast
fishing smacks, but sadly I haven’t been able to find a suitable engraving
from the correct era

‘As day after day passes and no tidings arrive of the missing Grimsby smacks, it is beginning to be realised that the gale of the 9th ult. will prove one of the most disastrous to the Grimsby fishing trade on record. altogether nearly a dozen fishing vessels, carrying between 60 and 70 hands, are missing.

‘Most of the vessels were provisioned for eight or nine days, and many of them have been out for over a month. Of the safety of seven of them all hope has now been abandoned.’

Report from: The Hull Times, 2nd March 1889

Most people of my generation with a long-standing interest in traditional music have probably sung this song at one time or another, particularly those who like me come from nearby one of the the East Coast major fishing ports.

It’s a big favourite with a magnificent, anthemic chorus, and a powerful theme, and it’s also a song that some of us connect with some remarks  made by old Sam Larner in relation to a storm he remembered from his childhood. Back in the 1950s, he told Peggy Seeger and Ewan MacColl that the big East Coast storm that people remembered was in 1884, and that there was a saying: ‘Oh dear, oh Lor – the dreadful fishing of 1884.’

Well, Jim Potter has been digging around and has discovered that the song actually refers to a storm in 1889, and that  some 70 hands from Grimsby – three score and ten – really did die that February night, as the newspaper quotation above shows.

This is February 2009, almost 120 years to the day since those brave and unfortunate fishermen met their deaths. As many sailed from Grimsby, we can assume that quite a few were orphans or had been abandoned by their parents and were often treated pretty badly by their employers and surrogate guardians, as Anson makes clear in his book British Sea Fishermen.

Anyway, you can read all about Jim’s research at Folk Leads, find the original fisherman’s poem from which the song developed and read about the Three Score and Ten fishermen’s gravestone that he has identified .

I haven’t been able to make the link to his recording of the song work, so if you want to hear how this one goes, you’ll have to make do with my recording of this great old song.
