Wooden Canoes are in the Blood
That's one way. I'm sure it works. I'm not offended by the copper splicing. I'm an admirer of Japanese broken pottery repair, kintsugi. I'm not using gold but I like the idea. It's a form of bragging in a way. The repair is obvious and gives extra value. To each his own.

If I remember correctly from the Walter Walker videos, (well worth watching for all wood canoe enthusiasts) there is a cotton strip between the stems and keelson and the planks on a longitudinal strip canoe. I imagine this is to help seal as the cotton will expand quite quickly when wet. I also seem to remember that wood to wood joints were varnished on assembly to help sealing.
This B&B canoe doesn't have cotton sealing though.
I do like the copper repairs with the patina! My rib canoe had a couple of very ugly galvanised patches which had no aesthetic merit whatsoever.

Personally, I would lean away from using anything as a splice that has a bending moment that is so significantly different than wood. A future "event" at the site of those more rigid pieces would concentrate the stress of an impact at the ends of those pieces and potentially cause additional breaks. With some background in tribology, I may be overthinking this, but if I were making a repair, I would probably lean towards a repair akin to what Samb has described.
I am in favor of using older canoes. Except for one, all of mine are used for camping trips. The idea that perfection is not going to last for the long haul is logical. I've dropped my Morris on a carry. I get it. That said, I would think that a wide board would not be ideal for heavy use, even extensively restored. Basswood is extremely soft and presumably easily damaged. I'm thinking this might be one that is best suited for fishing.

Hello MGC, Thanks for the comments. I'm facing two things I've never seen before. One of course is the abscence of canvas. Canvas and filler certainly makes a big difference since it's impervious itself and prevents leaking on a canoe that the light shines through before adding skin.
The second is the basswood itself. Every canoe I've restored has been cedar planked. I don't have enough experience to compare them well but I do think this basswood tends to feather or "fur up" more than cedar. Most of the planks are "fuzzy." I can see a reason for one coat of varnish before assembling the planks. It's too late to ask the builders since they are long gone. Perhaps there is record somewhere. I'm going to have to stop and think about this.
I'll also think about your mention of the copper pipe repair on ribs. I've had good luck so far but that only means one boat.

My first attempt at camping with a wide board canoe. I bought this canoe off Ebay nine years ago. I picked it in New Jersey on my way to Ontario. I tested it in the water somewhere in Ohio. It leaked. Not wanting to cancel my trip I resorted to various methods the seal the boat. Here you see tape and foam sealer. Nothing worked. I cut short my trip, went home and put this canoe on the rack with the WT Bush canoe. Since I now have four wide board canoes none of which are usable it's time to get serious. The moose and wolves are calling me. Ice out in April.
I agree with MCG about using copper pipes to repair broken ribs. The areas between very stiff and flexible materials in canoes tend to become 'fracture zones' which are prone to failure. Ironically, this is an issue for canoes made from both bark and modern plastics. One solution in some bark canoes was to put triangles of bark along the rails and stems to help reduce this issue. This may have been part of the original inspiration for Old Town's design number four as shown at https://www.wcha.org/catalogs/old-town/designs/design04.gif for example.

I've made every effort to save the old wood. Badly as the rot got to this basswood that means a lot of filler. I've used two types of filler. Two colors. Mixed poplar and cedar with oak. It's very ugly at this point. I'm not thrilled with this basswood. On the other hand , this canoe, as is, weighs 33 lbs on the bathroom scale. I knew it was light but thats really light for a 16 foot canoe. Because I had no model to go by there was a lot of trial and error recreating the stems and decks.

I'm a huge proponent of saving the old wood... where possible. If something is repairable such that is it structurally sound and aesthetically pleasing, I will make the repair. If, however, the repair isn't structurally sound and/or is unpleasant to look at, then I will replace with new wood, doing my best to replicate what was there (using other examples as guides if necessary), and working to match wood species, grain, and color. This can be very tedious but the result is both satisfying to the restorer and others and is best for the boat.
In this case, I'd almost certainly be replacing some ribs, battens, deck panels, etc. What's the point of saving original wood if its pieces are held together by filler and bits of wood of various species?
I agree with others about the split copper pipe. While I commend you on a creative approach to saving wood and making a canoe serviceable again, I agree that the junctions of wood and metal are points if significantly greater stress. And it's not just the ends of the copper - the fasteners, especially those that traverse the ribs from side to side, are additional critical stress areas.
Please know that all of this (my comments and those of others) are not meant tone negative or harsh. It's wonderful that you appreciate and are using these antique canoes. We're just offering suggestions based on our own experiences, offering help that might make your enjoyment of your canoes even greater.

Roger that. A wide board in any condition is a major challenge and one that is quite compromised makes it even more so. Ultimately you need to take our comments for what they are, well intentioned observations from the peanut gallery. Given the objective to end up with a boat that can be re-floated, you will need to do whatever you are comfortable with.
I tend to try and make sure that my repairs are reversable. I know that what I preserve may eventually be restored by someone with more patience and experience, so as a rule, I try to avoid (even though I love the stuff) repairs done with epoxy or fillers. Splits get repaired with splints, ribs get spliced or replaced, that sort of thing. You have generated some spirited discussion with this boat!

I couldn't find a table for comparison but what I can find is:
Basswood 26lb /cu ft 12% moisture, .......bends easy and split resistant
red cedar 22 lbs /cu Ft 12%,,.... bends ok but will split easy particularly the old growth
White Cedar `19 lbs /cu ft 12 % .....Don't know
I have a scrap Old Town canoe I got years ago in VT (our Treasurer?)
141 thousandths inch on thickness of planking vs .267 the Bush. Pretty much, The planking on this wide board is about double the Old Town
I'd better recalibrate the scale. It's more like 55 lbs as is.
In defense of my work. It was March 2023 when I brought it into the shop. The decks were in pieces and each piece rotted. The stems were rotted away. The wales were already scarfed several times and likewise, all four ends gone. I never found another boat for an example or pattern. I procrastinated until this winter. I began piecing the decks together trial and error. When it seemed right I put thick bracing underneath where it wouldn't show. Then set up the decks as best I could but with no idea what was the upsweep or if the stems curved back or what. I Kept adding filler and small bits of wood until it seemed to come together. The result is ugly but there's an old saying about newly birthed children and their mothers. "I didn't go through all this work for an ugly." It's mine and it's beautiful.
Now that I've gotten this far I can better visualize the decks. How was I to know there was a (coming) piece on both?
