1938 Peterborough Model 20 Repair Questions

Cross-posted from the "Song of the Paddle" Forums, at the suggestion of a poster there, apologies if you had to read this twice!

Hi there! I'm new to the forum, but have recently become the owner (temporary steward?) of my grandfather/father's 16' 1938 Peterborough Model 20 at my Dexter, Michigan home. Happy to say that the canoe itself is in pretty great repair, as are the spars, etc. The rigging and lateen sail, however, are another matter. I may have a line on a place here in Michigan to get a sail made, but I had some questions on rigging suggestions. To my understanding, this canoe needs replacement of the following: main sheet, halyard, sail lashing (for lack of knowing a more correct term), and the whipping attaching the awesome old wooden fairleads to the boom. I have found some advice on what sort/size of line to use for the main sheet and halyard (but would always welcome more), but have been able to find very little info on what to use for attaching the sail to the boom and yard, or estimating approximate length of line needed. Any help that anyone could lend would certainly be appreciated.

Also, I'd be very interested in any information anyone can provide about the sail assembly itself. Unlike a "traditional" lateen, the point of attachment for the boom to the mast is not about 20% of the way down the boom, with a hook or gooseneck. The actual point of attachment is where the boom and yard meet, where there is a brass yoke projecting out in front of both. As far as I know, this is original hardware, but I've never (in my admittedly limited experience) found a lateen sail mounted this way, though there do seem to be other styles that do this, generally for four-sided sails, though. This assembly would appear to either leave the yard/halyard attachment point well away from the mast when assembled and ready to sail, or would bring the boom up at a much greater angle than seems to be common for lateen rigs. Which is correct?

I'm more than happy to provide any further information that is needed. Given the current state of the weather in Michigan, photos are a bit hard to come by without sticking the old girl out in the snow!

Thanks,

Brad

 

Brad,

Welcome to the WCHA. You need to buy a copy of the book "Canoe Rig: The Essence and the Art," by Todd Bradshaw.
All your sailing canoe questions will be answered. It is available in the WCHA store and other places. Todd is a frequent contributor to these forums so he may chime in himself.

I have it These are the questions that I had left, after reading it. Though the book is wonderful, and while there is quite a bit about various methods for lashing the sail to the spars, there certainly aren't any recommended manufacturers/types of line for doing it, at least that I saw. I'm willing to be corrected I was looking to see specifically what brands and types of line people had used to good results. Also, everything that I saw in there about lateens was the standard, 20% back (a number I actually got from the book) mounting.

Thanks,

Brad

Wow! This is way more than I could hope for, thanks! I’m going to have to look at this more when not on my phone.

I had really wondered about the sail as a “leg of mutton”, but in Bradshaw’s book, it looked like those were rigged to a mast and boom. It looks like at least one of the Old Town pic links you sent had a setup pretty similar to mine! I will try to get some pics soon. Stuff is still kinda in pieces, but I’ll do what I can.

Thanks again!

Not quite sure the best way to insert photos, but here you go:



As you can see, the yoke met with an unfortunate gibing incident when my Dad was young, 60 years ago or so.



The view from the side shows how the yoke turns up (well, down in this photo), which I’d think would imply a not perfectly horizontal orientation of the boom.

 

I should, perhaps, additionally note that the boom is attached to the yard just behind this yoke piece by a (now deteriorated) strap of leather. The sail is similarly in rough shape, but from measurements I've taken, the angle between the luff and foot of the sail is roughly 61.66 degrees.

 

Possible, but not likely. What I'd think might be more likely is that an incorrect replacement sail was purchased at some point. I'll check into it, though.

Bests,
