Welcome to the WCHA.
If you are determined to build a Trailcraft for sentimental reasons, go to it -- but I think there are much better skin on frame canoes and canoe plans available today.
I built a Trailcraft kit canoe more than 40 years ago, when I knew very little about canoes and canoeing. If I were to build a SOF canoe today, I would NOT try to replicate that boat. I used it for taking a few day trips on the Housatonic River in Connecticut and similar waters, and a canoe-camping trip in Nova Scotia at Kejimkujic Park (which focuses on canoeing and canoe camping). The canoe was fairly crude, heavy, a bit tender, with none of the advantages that can come with a tender boat -- speed and responsiveness. I gave it away after little more than a year of using it. I remember that canoe somewhat fondly -- first canoe, first canoe camping trip, and I learned quite a bit building ans using it -- but none theless, I would not recomment it to womeone else.
Here are some sources for SOF building techniques and plans:
You should get your hands on Robert Morris’s book “Building Skin on Frame Boats” -- unfortunately out of print, and usually quite expensive in the used book market. But you should try your local library and inter-library loans -- this book is worth the trouble, in part because it contains plans for a nice SOF canoe.
Another book to get is “Fuselage Frame Boats: A Guide to Building Skin Kayaks and Canoes” by S. Jeff Horton.
Going back a bit in time, but still good, is Percy Blandford’s “Canoes and Canoeing” which is available used, and has plans and instructions for SOF boats -- his “Teal” looks like a nice canoe
Dave Gentry has plans and kits for three SOF canoes --

Look at Monfort Platt’s Geodesic Aerolite Canoes -- plans for a number of canoes are available
