I was thinking NuCanoe Frontier or Sportspal Canoe with 2.5 HP
Which 16 foot and under kayak/canoe has the highest HP rating?
I see those RiverHawk 15ft square sterns have a 10HP rating
My Meyers Sportspal S-15 is rated for a 5 HP outboard. It has the flat stern for a ready mounting of either an outboard or a TM.
But, the great advantage is that it can also be used with a paddle. It paddles just about like a large kayak.
With these sort of kayak-looking boats, it is either power on or no go. One has more range of options in a single vessel going other ways.
I'd give this one, the boat shown above, about 1 in 1,000,000 chance of grabbing any market share.
