There's all manner of useful information too which will make even the most landlubber of GMs sound like a salty sea dog and aid him in calculating how much treasure a ship can carry and even how long it will take to unload your spoils. . . .
If you run pirate games, or even those with a nautical twist, this is worth a look.
