Thanks everybody.
I got a low concert chair to put in the bottom of my canoe but I haven't tried the double bladed paddle while sitting in the chair.

Wow kayaks are really hard to get out of although I can easily get in. With a bad knee, getting out would be a problem, vs throwing your leg over the side of a canoe and stepping out. The kayak certainly seems more stable, but the stability of kayak or canoe depends on the person in it, both will overturn if careless.

I get wetter in the kayak and prefer rain pants over my sweat pants to stay dryer. Dryer is that what your name refers to?

I tried a canoe paddle in the kayak, that didn't work too well, but an old canoe paddle is good for pushing off the bottom to land or enter the water.
