I'd second the portabote suggestion. It's a lot more durable, takes up
very little space when folded, is easy to unfold or fold, and can
handle rocks, glass, fish hooks, nails, coral, etc far better than any
RIB. Probably a good deal less maintenance too, but I basing this on
six years of owning a porta-bote, and none of RIB ownership.

They also have full positive flotation and are exceptionally difficult
to puncture. They're also very stable in rough water and row much
better than any RIB. If you don't want to row and don't want an
outboard, they even have a sailing rig as an option.

For a LOT less money you can get a Porta-bote that will last 25 or 30 years. It
weighs less than a RIB, gives a dry ride, and you can drag it over rocks and
broken glass without worry. It also only needs 5 or 6 hp to put it on plane.

Having owned RIBs and now a portabote, I can tell you that NOTHING they
claim on
their website about the porta-bote is exaggerrated.
