My extended family sat down last night after Thanksgiving dinner and decided to play a game rather than sit and watch mindless TV. We played a paper version of Battleship that my dad hastily drew out on paper as remembered from his youth. He asked if I could use my skills to make cleaner version for future family game nights. It was a nice family time. I present Naval Battle for you to download and use for your own family gathering.
This isn’t technically an RPG but it is a paper-based game that only requires printing and pencils to play. Rules follow the Battleship game from Hasbro.

Wow. This is a great idea that I can’t believe I’ve never seen anyone else implement. Multi-player Travel “Naval Battle.” Simple. Elegant.
Thank you Dr. C, I have to say though that I do remember playing paper Naval Battle when I was a wee lad. I just reconstructed it.
Thank you for this recreation. I remember playing this in my youth.
Might I suggest adding two rows and two columns? It would make the game more enjoyable for a larger number of players.
We will be taking your suggestions and incorporating them into an updated and revised Naval Battle game.
