I think there's something to what you say.
Csaba Csere of CAR and DRIVER got to 'drive' a Los Angeles-Class Nuclear sub and he did mention that fully-surfaced,there was a sucking action which occurred at the air/water interface.Perhaps this goes away when the hull descends.With the sail/conning tower out of the water,the boat would lose nearly all of the sails hydrodynamic drag.
