For me, at least up till now, whitewater paddling and wilderness tripping have been two different things. I really haven’t been on a trip where the two overlap. I regularly paddle class II/III rivers solo in my whitewater boat, and tandem in my tripping boat (float bags, not gear). The biggest river I have done in the tandem is the Dead at 1800 (class II/III), and we made it down fine.
Of course, taking out the float bags and filing the boat up with gear makes a huge difference. I’ve done some quickwater/easy class I in a loaded boat, but that is about it. It’s hard enough to recover a tripping boat with float bags in it, I can’t image trying to recover one filled with gear in a significant rapid.
Hopefully that will change this year. I’d really like to do the St. John this spring – two class III rapids. I’d also like to do the St. Croix which has smaller rapids, but more of them – at least from what I hear.
We'll see...
