Very interesting. So the same forces that cause a Hobie 18's bows to be forced down are also the forces that cause a big, heavy monohull to keep going down, and down, and down because of the combination of sail area and that big lead thing below? Makes sense about the cabin not being closed. I'm sure that sailors who do races around the world are a little more savvy than a bunch of fun sailors doing a short-distance race after drinking all evening.
