Well, something like the T20 Character sheet, for the ship.
Ships get hit in combat, so I'll need someplace to record damage. Ships have plenty of data as well for Agililty, acceleration, etc, need to be able to record that sort of info in an easy to find form.
Ships have weapons like a character does, so a good weapons list laid out with damage, base bonuses to hit, etc, would be a must.
Ships carry equipement around like characters do, etc.
Without adding in the extra complexity of an AI computer system (which has its own stats, actual character classes and skills and experience points) I find a definite need for a "character sheet" for the ships in my game. The standard form is fine for summarizing the ships run by NPC's in a pre-printed module or whatnot, but considering how much time at the game table my group spends doing things with the ship this thing isn't just a vehicle, it's an important part of the entire Traveller game.
