Great work, I checked out the mininaval server the other day and I must say that's some very well thought out code right there. I a lot neater than my attempt at a naval mod at any rate. It's a pity that there can be so few cannons at once but that's the limitations of warband I suppose.
I like the conquest mode with the moving respawn flags especially. I assume you end the match by setting the losing team to zero tickets when all the ships are sunk?
How many shots does it take to sink your ships, by the way? I wasn't able to do it when I was in the server the other day as I didn't have the time.
