Your ship, as mentioned above, is too shallow. You don't have enough height, and the draught is too shallow. The stern doesn't look right, the rudder is too inboard, and the propellers are too modern for a ship of the shape you so far presented.
I would suggest you take your dreadnaught and instead of guns etc, give it a hangar deck and so on. It will be a start of an aircraft carrier as was done in real life 9Most early carriers were conversion of other ships - USS Saratoga, or IJN Akagi are good examples).
