Battleshots!

Game-Play:...
Player 1: B4
Player 2: Hit! (Glug, glug, glug) ... C7
Player 1: Miss! ... B5
Player 2: Hit – you sank my Destroyer! (Glug, glug, glug) ... D4
...
(Well, I’m sure you get the gist by now.)

These designs were made for a friend who was sent an e-mail of a drinking game which has been doing the rounds lately:  

So I designed a range of "Battleshot" ships, and made a sample for him to inspect - check out the models here: http://www.thingiverse.com/thing:13846
