rules for fighting on the deck of a ship during a storm

[moon glum]

Are there rules anywhere for fighting on the deck of a ship during a severe storm? I want some rules that take the severe winds, heavy rain, rocking deck, and giant waves that splash over the bow and threaten to wash people overboard all into account. I could make some up using the weather rules, but I thought that there might be some rules in, say the Skull and Shackles adventure path, or the like.

Thanks!
