  1. Your trying to fix a problem that doesn't exist. The designs are proven to work. Never had a frame failure that I know of. A little flex is part of the design. You really should try one before you start trying to fix the problems.

  2. I bought a Torqeedo 1103 from B&B. I have only had it out once. I had a max speed of 5.4 knots and a range of 10 nm at various speeds. Some of the earlier Torqeedos are not as quiet. The 1103 is very quiet. The first time I started it up I gave the throttle a little twist and did not realize the motor was running until I noticed the boat moving. Ease of starting, no fumes or fuel onboard, and quiet those are the real advantages in my mind. The Torqeedo is significantly more expensive and it is 8 or so pounds heavier than the Suzi, and Honda but it is lighter than the Tohatsu. I hope to have the boat on the water for some testing soon. Torqeedo lists the 1103 as 3hp equivalent. The gas engines will likely have a somewhat higher top speed and of course there is no comparing the range. Time will tell but I think the electric has real potential.

  3. Cousin Sailormon: That's an interesting design concept. The core question is whether the flex experienced with the standard design is, in fact, a problem. There will always be some flex in a boat, even with your stiffening modification, so how much is acceptable? Some structures need to be quite rigid to fulfill their design requirements. Others require more flexibility. What degree of flexibility is optimum for a kayak? It is likely that flexibility improves hydrodynamics up to some point. To me, it feels a bit like a solution looking for a problem. I built and paddle a Ravenswood, which is 15.5 feet, not one of Jeff's longer boats. I can feel it flex, especially when there is chop of a certain size, but it doesn't constitute any sort of problem. If I were building a longer boat, I would pay attention to the type of the wood I used (both species and individual sticks), scantlings, and the grain (straight with minimum runouts). Fair winds!
