I have no idea if canoe prices are going down. I find the type of boats people use is very regional. Inland in the state of Maine I expect to see a lot of tripping canoes (old town) on cars. I suspect it might be true in Minnesota as well although I haven’t made it there to paddle yet. My guess is more lighter composite tripping boats (wenona) there. In the adirondacks (NY) I have seen a few pack canoes but a lot more standard tripping canoes.
In the midwest is where I have seen racing canoes- jensens but again mostly a lot of standard rentals. In hawaii outriggers, including those high end carbon fiber singles.
In the southeast- on the ww rivers there once was a very active ww solo canoe community but perhaps that is fading a bit- daggers, whitesell, bluehole canoes seem to have all faded. Mohawk moved to tn at some point. I haven’t noticed a lot of specialized canoes in arkansas or missouri or texas, just standard rental stuff. In fact I was shocked to see someone fishing from a pack canoe on the llano river. Mostly though sit on top kayaks seemed to be the norm in texas and oklahoma. In wv not a lot of canoes- ww kayaks, rec and fishing kayaks, and rafts. You pretty much have to go to a summer camp to find canoes where I live. I see more canoes in Ohio than in WV.
Nationwide the liveries are changing from canoes to single recreational sit on tops like the jackson riviera.
