What really doesn't make sense is why do people want the Navy ships? Not to damper anything, but aren't they the same ships with different flag designs? I mean, besides hull protection, I don't really see a difference. Or are we assuming they would have the broadside ammo they have now, versus normal cannon balls..? If so then never mind xD. Anyways, I would get Ship Of The Line (Obviously

) And maybe the
Revenant or
Phantom (See, I put
Italics around my ship names because its
fancy fancy! 
). Seems like a nice ship and all.. You know, once you get past the rotting and cobwebs, its all good from there!
