I'm looking at getting an inflatable dinghy as a yacht tender but what should I consider? I figure the collective knowledge and experience here should be able to point me in the right direction. I'm looking for something that can carry at least three people but I can stow on the foredeck of a 9.5m yacht and be able to drag up the beach and launch single-handed so not crazy heavy or large. I'm tending to an alloy RIB but I'm open to suggestions given a good reason. I don't have an unlimited budget so second-hand is also an option. What should I avoid and what should I look for?
