Optional rules for D&D v3.5
I was not happy with the ship combat rules in D&D v3.5 so I came up with a system that allows multiple ships to combat each other and, at the same time, allow for each PC to contribute in his own way each round. I simply (or not so simply as it turns out) extended the D&D combat rules to work with ships as well. What I came up with is in a PDF file you can download here: Ship to Ship Combat
There is also a fast start version here: Ship to Ship Combat (fast start rules)
You can use this to keep track of your ships: Ship Record Sheet
I would really appreciate any comments, especially if you use them in play (they have not yet been play-tested).
