Others have so why take the time to recreate the whole process especially when I don't have the proper equipment to do it so that others will accept my results. I can also attest to this from personal experience. I used epoxy to glue my strips on the canoe This did not help the butt joints too much but did increase the weight of the finished boat by quite a bit. On the up side, it is very strong. The problem with a butt joint is the contact surface area. Butt joints minimize surface area and that is one of the biggest reasons they are weak. I read in a book on boat building, sorry I don't remember the exact one I've read so many over the years, that some school had run several tests on joints that maximized strength and minimized waste. They found that the 12:1 scarf joint was the strongest. With a cove and bead joint having about 1/3 more surface, it should gain strength both from a mechanical and surface adhesion aspect. This is why it is important to do a good job milling your strips. I went one step further than most and ran all my strips through a thickness planer to make them very uniform. Another thing you can do to minimize the angles of the joints is to use thinner strips. This does, however, increase the amount of glue and number of staples. You can also get a much more uniform curve over small radiuses.
