“I am planning to clamp the inner gunwale and mark location, then drill through the existing holes from the outside into the inner gunwale and was hoping to to be able to use the existing holes or at least most of them. Does this sound feasible? By the way I've plugged many teak holes on my sailboat and feel your pain”
I think ALSG answered the question, or at least the wood part of the question. He still hasn’t answered the question “
What does YAER weigh?”
I will chime in. It is certainly “feasible”, at with the inwale holes until, if necessary, the few holes just at the stems. What type/style deck plates you plan might come into play at the stems as well
A 90 degree drill adapter might get you a couple more space-limited inwale holes further forward (or backward) if desired.

There are tight-space times when a right-angle drill adapter is dang near the only way to go.
My principal concern with trying to exactly hit the old screw holes through the hull is the hitting the old sheerline holes
exactly part; if I start putting screws in and something goes ever so slightly misaligned, up or down, front to back, I fear I would drill overlapping Venn diagram holes through the sheerline, with holes overlapped.
With tightened screw “clamping” the inwale/outwale into place those overlapping hull holes might not matter that much. Still, I’d prefer a nice, tight screw hole drilled through virgin sheerline. If I didn’t care about the boat, planned to sell it or flip it, “
Who cares, can’t see, just screw ‘em on, but the Indy is a keeper canoe.
A couple of the first derelict canoes I ever rebuilt had already been (poorly) wood-regunwaled once before, with some rudimentary
attempt at hitting the old hulls holes. There was a lot of Swiss cheese, and more than a few overlapping holes. T’was a fugly sheerline to work with.
If any of the existing screw holes along the sheerline were factory ill-spaced, or you if opt for different gunwale dimensions or profile, eh, what then?
Factory wood gunwaled RX Yellowstone Solo. There was ¾” of depth of factory gunwale depth to work with, and some of the the drilled holes are only halfway in the sheerline? I want some depth of screw (or pop rivet) purchase at the edge of the sheerline.

That’s not the only Friday afternoon factory miss-drilled example. And I wish I had Swiss cheese photos of the twice regunwaled old Explorers and Shenandoahs. Or our Independence, which had rotted original wood gunwales, drilled with well centered holes, but the original owner had hull drilled it below the wales for float bag and gear lacing, and there were some too-close-for-comfort holes.
Or other too-close-for-comfort holes. Can’t see it in the photo, but on the inwale side there is an oopsie-spaced gunwale screw hole barely ½” away from that being-epoxy-filled thwart hole. Moving the thwart a couple inches to avoid that intersection was no big deal.

Thwarts can be repositioned a bit fore or aft. But I want the hung seat where it factory located was, or, as often, where I want it, and that gets to be a pre-panned math issue, avoiding too close intersections between gunwale screws and seat hangers. Trying to calculate 6 or 7 inch gunwale screw spacing non-interference with an 8” or 9” seat frame, ARRGGHH, my head exploded calculating the math problem.

Hole spacing matters, especially with hung seats; vertical machine screw gunwale holes too close to horizontal gunwale screws are a no-no. I felt better seeing a highly regarded builder make that epoxy-plugged hole mistake.
But, back to the gunwale screw holes, once I start drilling and putting screws in how can I tell if I’m perfectly aligned with the old hull hole?
That is a serious question. I’d like to know if there is a secret trick to that “
Hit the old holes exactly” regunwaling.
While I doubt I’ll ever regunwale another canoe with wood, it
could happen. I’ve always chickened out and spaced my new gunwale screw holes between the old holes, plugging the old holes with epoxy, or, on the real Swiss cheese of sheerlines, running a strip of fiberglass tape and epoxy along the inwale side on composite canoes to add some structure to the cheese.
