Battleships
New rules: All of these large ships  have the limited turning disadvantage (but can attack in any direction).  Also, flank/rear shots against ships do not get a bonus. Lastly, all ships are assumed to be both water bound and able to transport a number of stands equal to their 'Def.' value.
