So noted. However, those ships had the guns, fairly logically located just fore and aft of the island, not in turrets at the bow of the ship, interrupting the flight deck. Such a design as this was obviously stupid, even to most of the minds of the day.
Remember, this isn't a cruiser with additional seaplane facilities, here the deck is supposed to be an integral part of the ship's operation, yet its utility for such a role is obviously curtailed by the dumb setup.
Kaga was done this way at first in 1930
Triple deck, the lower deck could be used for take off, but was only 180 ft long, vs 560 for the main deck.
That cruiser doesn't look that bad in comparison.
The US carriers also had open bows, but for catapult operation from the hangar
