The ship would be as long as the class ocean, and I bet it would reach 13 knots of speed due to its length, and the ports of the guns would be at the same water level of victory (just look at the mamudieh and hms duke of wellington that was probably going to be heavier than the duke of kent), a project possible in the 19th century, and that certainly would add originality to the game, then if you do not want it you just do not use it.
