Gotta correct you there Mr. Dew the presence of water does not make the weight of the ships any lighter !!!
You have fallen for the optical illushion of the big floating ship as in somehow it must be lighter weight. Wrong instead they equalize due to buoyancy displacement but the weight is still there.
Not at all. Every bit of the ships weights plus the massive weight of the water MUST be taken by the bridge columns and I bet they are heavily reinforced and very FAT !!
