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.

The model’s parts all fitted, so far as I can tell at this scale,
which shows there are no serious mistakes here. The
glasses case isn’t essential…

Julie and I cannibalised the card from a pack of Lidl’s Soviet-style wheat bix (my favourite, for some reason), used Pritt glue to stick 55 per cent sized prints onto the material, cut the thing out and then assembled it in the traditional skiff fashion – attach bows, bend around central frame, attach stern, add bottom, attach everything else.

It only took a few minutes and yet again the magic worked – and a serviceable if rough model boat popped up in what seemed like a moment.

It was all very satisfying. All the parts went where they were supposed to, which at least proves I haven’t got any of the important components mixed up, and the darn thing looks the way most of us would expect a modern skiff to look – and no doubt it will perform like one too.

I think we’re set fair to finalise the plans for the stitch-and-glue/tack-and-tape version of this 15ft 6in flattie skiff in the next week or two. I’ll make them available for free from this website, and elsewhere. More traditional chine-log construction plans will follow, and after that, who knows? Perhaps a variation or two will suggest themselves…

If anyone else is following this progress and has built a model, we’d love to hear from you at gmatkin@gmail.com, and to be able to add your photos to this post!

construction lines!

I won’t say too much now as it’s after midnight, but I’ve made some useful progress.

The drawing is a mess with so many construction lines still in place, but it shows all the major panels mapped to the ply sheets. I’d like to think that most of you will make out the bottom, sides (with their traditional subtle S-curve), sternsheets and major frames, and that you can see the beginnings of a set of boatbuilding plans.

There are some smaller panels to add – breasthooks, knees, odd reinforcements, top for the thwart and so on – but most of the boat’s key components are here. The next job, though, is to create a printed sheet for making a model (I hope to publish that very soon for those who are interested), and after that I’ll be adding coordinates. But now it’s time for bed. Keep on turning, big wide world…
