I was in your position recently. I was switching from 14 ft. cataraft to raft. I had a 12 ft. raft for awhile. It was super fun and easy to deal with (Hyside), but not enough room, especially not with a passenger. I debated a long time between a 13 & 14. Most folks pointed me to a 14, and that's what I got. I just inflated it, and it looks great. Not too big.
