But what is implied by a U-boat pro- ceeding on the surface during a storm ? It is always plunged up to the turret in water, and even the turret is cov- ered by the waves. The seas go over the entire boat, since it is too heavy to be lifted like an ordinary craft and because, unlike a steam...er, it cannot bring its ''reserve displacement" to bear by boring into the oncoming seas. Its entire body is already submerged, and so it cannot possibly increase its displacement by plunging in still more deeply — thus attaining more buoyancy and momentum.
