Boats as Art


Years ago at an art show I got in conversation with a very well known major Scottish artist famous for her countryside paintings. who asked me if I painted and when I said I didn't terminated our conversation pretty quickly. Later I realised that if people like me didn't build boats people like her wouldn't have them to paint.

Fife famously liked his boats to be "fast and bonnie" and I think most of us who make them would agree. It's difficult to imagine how one could be motivated to spend a year or two building something plain ugly, but then, I hear you say, there could be some functional beauty? Did Fife's lovely long overhangs really contribute anything other than weight where you don't want it and corners of damp rot?

Above is my wee Christmas Wherry, designed by Walt Simmons of Duck Trap Boatbuilding, which I think is pretty as well as functional. She is seen in her present configuration and colour scheme and has arrived here by quite a tortuous route.

In the early days she had a centreboard, set fairly far aft, and no jib. As a result she tracked along nicely but made a lot of leeway and was a pest to put about. This led to the centreboard being removed and replaced by a dagger board a couple of feet forward, which cured the tacking problem at the expense of introducing quite severe weather helm. In turn this led finally to the jib and bowsprit, resulting in pretty good balance.

The forward dagger board has cleared the internal space, which is better for the crew, but in turn produces the constant problem that one of Argyll's travelling rocks will spring up unexpectedly. When the current season is finished the centreboard is going back in, positioned somewhere between its original place and where the dagger now sits. Here you can see the remains of the original centreboard slot, and the daggerboard box forward.


This image shows another truth about the boats we build, which distinguishes them from artworks. Once they're done we lose interest in maintaining them. The inside is an utter disgrace and will be totally repainted when the centreboard is done.

From the outside the good ship Kelpie still looks ok and the sprit-sail, made by Gayle Heard twentyfive years ago is still setting well.


The sprit is both lovely and functional and an excuse for nice things like rope grommets.


And with a little boat like this you can enjoy extravagances such as the tiny blocks that Harry Spencer made for me in 1990, with farthings for keepers.



Come to think of it, they're also functional as well as pretty.

Survival of an old Lady - Chapter 4 - she swims again


Stroma's old mast and sails were in very poor condition and I had decided at the start of the project to replace both, because I intended to sail without an engine and needed the sail power to be totally reliable.

Scottish Islands ODs were originally fitted with engines, either a single cylinder Watermota or a Coventry flat twin and the Class had a rule that if you didn't fit an engine you had to have a dummy propellor and carry equivalent weight. In fact these early engines weighed very little, roughly the same as a decent bower anchor and chain. Certainly even the smallest of modern diesels would risk unbalancing the boat and I had no intention of going back to a single cylinder petrol motor in view of the fire risk and the fact that kept in the damp space beneath the cockpit sole it would never start.

I ordered a mast from a major, well-known company and was extremely disappointed when it arrived. Rather than the pear-shaped profile of a traditional mast this was simply a round, tapered stick and as a result seemed very thin at the top. Fortunately a friend was looking for a mast and when he didn't agree with my assessment this first attempt went to a good home and I recovered some of the cost. Sadly it broke a few years later during a race in blustery conditions.

After taking advice I found the wonderful Alastair Garland, who needed absolutely no instruction from me to produce a spar that was a work of art, as well as extremely strong. 

The new sails came from the legendary Gayle Heard of Tollesbury, whom I already knew, as he had already made a suit for Sonas and a spritsail for my wherry.

Stroma was rigged, as Sonas had been, by Iain Gillies, the former head rigger at McGruers and a man of great skill and humour who became a good friend.



It would be tiresome to recount all the remaining steps up to September 2003, when Stroma finally hit the water again. I'll just say that as the launching date draws ever nearer the list of undone tasks becomes longer and longer.

It was a great relief to find that the weight of the materials I had added to give strength and customise the interior had exactly balanced the saving that resulted from having a hull that didn't absorb water, with the result that Stroma floated level and precisely to her original marks.

Survival of an old Lady - Chapter Three


With Stroma near home in Argyll I could speed up progress by working at weekends rather than weekdays when the normal job allowed.

The first task was building the cabin sides, from marine plywood that was later given a good outer surface of mahogany from a beautiful big plank that I had come across.

Decisions had to be taken about how closely to follow the design. Alfred Mylne had drawn curved corners at the front end of the cabin, but McGruers had built them sharp, starting a debate on which was authentic, with Mylne winning.

The cabin roof proved challenging with the curvature flattening forward.

As work proceeded individual components became more intricate and demanding to make, but also more fun.

I spent a lot of time wondering how to replace the original rudder stock trunk, which seemed to have started out in life as a piece of iron drainpipe. It had rusted almost through and could have sunk the ship in seconds had it collapsed underway. I couldn't find a satisfactory replacement and was worried about the tendency of plastics to behave in strange ways afar prolonged exposure to water. Eventually I decided to make a tube from thin staves of Western Red Cedar, barrel-fashion, coated with woven roving and then protected from any glancing blows by a stout ash timber glued on the forward side.

Survival of an old lady - Chapter Two - ends in evil thoughts!


The first step in any restoration is to discover how much you've let yourself in for. Stripping off the deck revealed that most of the deck beams were either burst or rotten.

The stem was in a disastrous condition. It would have been made from a piece of oak selected for its curve, but the yacht was damaged at Hunters Quay sometime soon after the War when a ferry ran into her and a couple of feet had been replaced at the top. The original and new sections were both seriously rotten, quite a common problem when you consider how susceptible oak is to fresh water.

There's a special sort of archaeology involved in rescuing old boats. While received wisdom says that the ancients always produced dovetailed joints we found that the deck beams had in fact been lodged in notches in the shelf with each held in place by one iron nail. The elm frames would have been steamed and pretty hot when put in, so it wasn't surprising to find that quite a few had failed to find the little sockets in the hog that had been made for them.

It was obvious that the stem would need to be replaced. To keep the hull in shape I decided first to repair the beam shelf and reinstate the forward deck beams. Here is a sequence of images showing my late pal Duncan working on the rotten shelf and our efforts at scarfing in the new sections. A couple of months later I sat beside Duncan in hospital and he made me promise that I'd make sure "she'd swim again".





 



While doing this we made and fitted the forward deck beams.

After the forward stem was removed the hull was kept in shape with a system of wooden blocks to keep the planking in line tensioned with Spanish windlasses.


Using the old stem as a template I made the new one alongside, from clear Douglas Fir laminated with epoxy.



Attention turned to the area at the foot of the stern post, where removal of planking revealed that the post itself was split. I made a new one. Likewise the transom had been badly damaged at Irvine and was replaced. Unable to find a suitable chunk of mahogany to handle the radius the new one was laminated from marine plywood.


Up to this point I had hoped that I could complete the job without taking Stroma off her ballast keel, but it was now clear that this would be necessary.

Excavations at this point showed that the hog was badly rotten, also the floors, while not totally rotten, had numerous shakes. It's an interesting speculation that most of these probably occurred soon after Stroma was launched in May 1929, as they had been built from oak crooks selected on the basis of the shape being approximately correct. I have read that members of the McGruer family would scour the woods looking for suitable pieces for this purpose.

It was going to be impossible to find suitable pieces of oak to build a new hog and floors, even had I wanted to. Availability of top quality marine plywood meant that they could be built to a much higher strength and durability than had been possible first time round. Here, the patient has just been lifted off her keel and the rudder dropped out.


The keel is carefully shored to keep it in shape. Originally she had eight bolts, positioned diagonally, worked from iron, which remained embedded in the lead after the sections through the hog had rusted away. The ones you can see are four of five bronze bolts added later, the fifth one being a little short fellow though the front. I was later to stand on the keel and drill another eight holes, staggered opposite the original ones, just because I felt I should. It was an interesting exercise, which included me being thrown off once when the drill bit caught in the lead. The end result is that Stroma now has a ridiculous number of bolts.


Here are some of the new floors in place.


And the new hog and stern knee.


And finally replanked.






At this stage, with new carlins and all the deck beams done, Stroma was beginning to come alive again.








At this point I began to have evil thoughts about giving the whole ship a sheathing of woven glass roving and epoxy. I won't write a long essay about the pros and cons of doing this, as it has been discussed endlessly, usually be people who have no experience of doing it, but may have come across some of the disastrous fibreglass and polyester jobs that were done in the 1950s and 1960s. My friends in the Freundeskreis Klassiker Yachten even have a name for the process, which translates as a dead man's winding sheet.

After very careful reading of all the literature I could find, plus discussing with my boatbuilder friend who had at that stage built about sixty boats (now up to about eighty) with no problems, the decision was made. My reasoning was that having basically replaced everything that in the old boat could absorb water and swell with materials that couldn't the gain in strength and stability was worth the expense and work involved. While the yacht was off her keel the coating could be taken round the hog, avoiding a major reason for not doing it.

The hull was now careened to get proper access and the work done over a very hard and messy weekend under the professional supervision of my good friend Richard.





Now, fully put back together again and much stronger than when she was built, I decided to bring Stroma a hundred miles nearer home in Argyll to get on with the work of reconstructing the cabin, cockpit and interior to Alfred Mylne's original design.
