HIGH SPEED VESSELS
REDUCING LOST POWER. While travelling on board a merchant vessel which was dodging German cruisers during the early days of the war, Dr A, P. Thurston, a British scientist, carried out some interesting experiments on the distri-
bution of wind pressure and velocity around the ship’s futmeL The results of these ex'periments, which have just been published, show some curious arrangements of suction and pressure according to the direction of the wind in. relation to the course of the vessel. One fact brought out is that quite a considerable amount of horse-power must be lost in driving the dead surface of a vessel against a head wind. Dr Thurston therefore suggests that the experiments should be repeated over the wofe of the
upper structure of a vessel so as to reveal those portions which present the largest amount of bead resistance. This information would, he maintains, be most useful in designing high speed vessels, and would enable the efficiency of designs to be'* improved without sacrificing the comfort or safety of the vessel. In destroyers and cruisers the wind resistance of the superstructure is n very important factor.
