My understanding is no for rafts and cats, you need a pack raft or ducky( or pack cat). Check out what the BLM says about it, as well as past threads, sounds like it tends towards a backpacking trip with some floating. This year could be staying in your boat though, could be the time to run it, with the current snowpack. I'd love to go.
