It could be any ship, but you'd have to declare it ahead of time, and making it submersible will cut its weapons down by three quarters. Diving and Submerging would be something that'd take at least a minute. Diving before retaliation would only occur against the most inept enemies ever :p

Unrelated question, can ships with flying runes be in the water or are they always in the air?
