well its more of an unfortunate intentional lack at this point since the only reference (that is par with the upperworks) from the hull is a slitting wiev that doesent really reveal the actuall size nor form of the hatches (since they are traverse from the centerline). Therefore I cannot present all the details there yet (there are other hatches there as well, for pumps and such). If someone has better references regarding them, I would be happy to continue my work
