In the Pac Northwest most cruising boaters are making the switch to RIBs. They used be complelety non existant but are now the standard. Folks finally realized that not having to worry about wacking the side of the boat is a pretty nice feature. Plus they generally tow well if you need to do so.
For cruising powerboats we are seeing a lot more of these:
They make an aluminum hull version that is really light. The rigid tanks are nice for powerboats that use the stern step to store their tenders on their side.
There are products out there for doing the same with a RIB and it works out nicely.
Otherwise, just find a 10-12' RIB depending on beam of your boat. In the US the most available inflatable tenders in that range are: zodiac, achilles, novourania, walker bay (light weight plastic hull), West Marine (if you must), Caribe, AB. In Canada their are the same options plus several Canadian and European makes as well.
