I like the name of the ship (as would any former Sky Invading Rhinos [SIR] member).
As for the ship itself, I'd argue that any new ship has to stick with the same basic principles as any of the other ships: 1 Hull Armor, 1 Balloon, and at least 3 Engines either Light or Heavy Engines (though where the Squid has just 4 Light Engines, a ship with just 2 Heavy Engines that has great acceleration and velocity, but terrible turn-time might be interesting, that side-note aside). A ship with 2 Hull Armors might be a bit much.
Assuming the ship only has 1 Hull Armor, it sounds like a weaker version of the Galleon in terms of firepower and weapon placement, with its double broadsiding heavy weapons, though I suppose the exception is that rather than 2 heavy weapons, there's 1 heavy and 1 light weapon...and the token aft light gun.
Just my unasked for , 2 cents..
