I don't know anything about Kevlar. I have seen many monohull fiberglass boats up on reefs and most of them could have been removed, except that most reefs are too far from anyplace to make salvage feasible.

The article I referred to, "Fiberglass Rules" gives examples of strength and abrasion resistance that match that of a steel hull. But they were all monohulls.

After the Queens Birthday Storm in the S. Pacific, two of the fiberglass boats abandoned by their crew ran up on reefs, but weren't salvaged. One had been dismasted in the storm and had been expected to sink but didn't. I don't know what happened to that one. The other blew off the reef in another storm and was blown away, apparently to either sink or come up on another reef somewhere since it wasn't found (but it did not sink immediately after blowing off the reef - it wasn't holed). Monohulls.

I just don't like steel boats and the compromises that are necessary in them for what seems to me to be little to no advantage when going up on a reef. It seems to me that there's a lot of people talking about how much safer steel boats are, but I don't recall any examples of a steel boat surviving an encounter with a reef because it was steel and wasn't holed.

Or are there? Anybody have some examples?
