I thought I'd poke around on this and first I found was

Bill, the law you have linked—chapter 13 of the Copyright Act—is called the Vessel Hull Design Protection Act (VHDPA). While the VHDPA was placed into the Copyright Act for administrative convenience, it does NOT give copyright protection to vessel designs. It gives a
sui generis (unique) form of protection that is not copyright, patent or trademark.
I have explained the provisions of the VHDPA in detail, and why no canoes are currently protected by it, in the thread you linked at this post (and others that follow):
So I have an OT Appalachian that's 76# that I really enjoy and a raven stripper that I built last winter at 59# (I'm still not sure how I will do with it in the very bony sections of the Allagash). Can I legally use the Appalachian as a male mold to make a composite version?

I further explained in that thread that canoe design PLANS (on paper or digital) can be copyrighted. That just means if you legally acquire such plans, you can't make a copy of those plans. But you can copy any canoe hull by plug molding ("splashing") unless that hull is currently registered and protected by the VHDPA, which, as I have explained, no canoe currently is.
Everything I just said applies to U.S. law only. I have no idea whether or how Canada or any other country gives intellectual property protection to canoe hull designs. For an in depth description of the VHDPA from the U.S. Copyright Office, see here:
To circle back to the various scenarios being discussed in this thread, I'll summarize U.S. legal concepts.
- Any canoe can be copied by plug molding the hull because none has a current registration under the VHDPA.
- A person like Blue Valley can get a copyright in canoe design plans that it originates. If those plans are sold to you by Blue Valley, you cannot make a copy of the plans. But you can make as many boats as you want from the plans, except:
- You can be limited in how many boats you can make from the plans if the Blue Valley contract under which you bought the plans has a contractual restriction. This is a matter of contract law not copyright law. Blue Valley can contractually stipulate that you have to pay $X for each canoe you make from the plans after the first one.
- If you make some sort of "significant change" to the second boat boat you make, then the contractual obligation to pay $X to Blue Valley probably would not apply. Blue Valley would have to take you to court and prove your changes were not "significant", an inherently ambiguous word.
- A final situation can arise if you give or sell the original set of plans, without making any copies, to a third party such as me. Under contract law, I arguably am not bound by the $X per extra boat restriction because I was never a party to a the contract between you and Blue Valley. In fact, I may not even have knowledge of that contract. I do know I can't make a copy of the plans because of the required copyright notice on them.
