I am finally getting ready to purchase my first raft. I am looking at purchasing from a local raft manufacture out of Durango. However, they only offer two lengths of rafts 12' and 15' I have rowed commercially for 8 years. Mostly on 14' boats. I will mainly be on class III rivers. However, it would be nice to do the occasional week long trip on the San Juan or overnight trip on the Upper Animas. (class IV-V). I am not sure what length to go with. Should I just go with the 12' knowing I will mainly be on class III water? and when I want to go on those occasional trips requiring a bigger boat attempt to find someone to go with that has a larger boat? Or should I go ahead and spend the money on the extra 3' (~$1,000 difference) to have its capabilities when I need it? Any thoughts would be greatly appreciated. Also I have looked at the boats in person they seem to be good quality. The brand is zoik.
