I recently traded our 10' Caribe Light for an 11' version of the same model with a broker buddy of mine. It's a long story, but the end result is that he is selling our old dinghy. It's in Stuart, FL (oh, the irony) and is in good shape, I bought it new in 2007 and kept it covered. He hasn't tried very hard to sell it so far, but I know it will go quick when he does.
The Caribe Light has a fiberglass hull, but it is much lighter than a standard rib. It's a great dinghy, which is why I traded for another one.
Let me know if you have any interest and I can put you in touch with him.
