This is basically a good, if simple, naval combat wargame.
It's pretty simple: Roll the dice, confirm hits, do damage, next round, draw a card, see what you can do.
Ships are given a few factors that make the game fast, though I can't really vouch for how accurate it is, not really being a nautical guy (I've read Hunt for Red October, but that's as close as I get).
If you want naval warfare, I recommend this, if for no reason other than the fact that for $15 and a bit of ink and paper, you get a fully-featured game.
My main gripes: No plain images of the ships for us digital favoring players, meaning I get to find ship images myself, or use proxies. Also, the action card system could result in long periods of time consisting solely of inaction, as ships move over and over, without firing.
