I would suggest leaving it like this. If a game times out, or ends for some uncontrolable circumstance, your ships' location will be revealed for your opponent, making it impossible to continue the game and forcing you to restart the game from the beginning. If it is a tournament game, that would slow down the whole tournament and render pawns like yourself who are in that tournament unable to join another until that game is complete.

Although the same problem could arise in Dark Chess, i like seeing where my opponent's pieces were, and be able to play through the game in that :-)
