I think something with a full tang would be good for the situation you have described. I have a stainless Model 15 with sawteeth on order from the Capt. as we speak that I plan to use for kayaking (Among other things). I like the shorter blade for carrying when seated.
I do like Tony's idea of the Model 14 with sawteeth. That was my first Randall that I bought many years ago (Back in the early 80's). It now belongs to my son:

I also had a Model 16 with sawteeth for many years. That one now belongs to my son-in-law:
