Somehow a spiling batten still seems to be the quicker, but just as accurate method as building ply or cardboard templates. I can understand (and have used) cardboard templates that fit into a hull, deck, floor, but why reinvent the wheel when it comes to planking? Just seems like a waste of time to me.

Re: JIM, an 18 foot canoe yawl.
What I like about the trussed template idea is that it is self fairing in that it gives top and bottom battens to sight, it then gives a router guide for the next step.'' You ain't gonna learn what you don't want to know. ''

Re: JIM, an 18 foot canoe yawl.
It strikes me that running top and bottom, self fairing battens to use as router guides is still going to be about 20 times quicker run betwixt compass points than stapling, or hot gluing hundreds of little truss chords that have to also be made in the first place, cut to size during the spiling process and then disposed of. If you're building more than one Jim then I'd say it would be a worthy process. Besides, the lead at the end of a compass is just about free for cost!Jarndyce and Jarndyce

Hmmm, not that many bits, probably ply squares or triangles in my case plus gyprock screws and the trust battery drill.'' You ain't gonna learn what you don't want to know. ''

Re: JIM, an 18 foot canoe yawl.
I have to say I've always thought the trussed template method was a lot of busywork. Compared to a simple spiling batten it is infinitely slower and not a bit more accurate. The one thing the trussed template does provide is a pattern that can be used with a router to cut the plank shape.
However, and this is a big one, I always cut my planks about 4mm oversize on both sides, then offer up the plank for a test fit, and then do the final trim. If you're using a trussed template, and cutting to its exact shape, you better darn well be sure your template is perfect, because there's no extra meat on the edges for adjustment.
A simple ply spiling batten and a compass are all you need to exactly record the plank shape from the boat and molds. Once these points are transferred to the plank stock, the dots are connected using a fairly stiff fairing batten, assuring a fair curve to the plank edges. Cut the darn thing out a bit oversize with a skillsay and clean the edges with a low-angle block plane. Then do a trial fit, trim a bit as necessary, and hang it. It's the method developed by the old timers and it still works just fine today.Comment

Re: JIM, an 18 foot canoe yawl.
OK I'm hardly an old timer just a backyard hack but I'll throw my spiling batten into the ring and say having done it both ways compass spiling is quicker, accurate (just make sure you remove previous marks) less wasteful and more satisfying but hey as they say whatever floats your boat.
Just a note on the truss method 1" or so ply battens instead of wood work better as they conform to the hull shape easier.

Re: JIM, an 18 foot canoe yawl.
I know spiling works ! There's really no argument, I guess I just like the aesthetics of the truss.... we'll see how it goes when that job arrives but Jim says planking is a little way off. I'm just about to rip the laminates for my stem and stern post inners .'' You ain't gonna learn what you don't want to know. ''

Oi Peter, you sneaky bugger! There I was in blissful ignorance waitng for your thread to start and here it is already! It's great! Good luck with the build, the design looks really nice (although it now looks like we're going to have a plague of sprits up there in the deep North!). I like the little trusses method too - it just eliminates so much of the room for error. I'd go with the air stapler though.
