Ship project history: The first of the famous 'flush deckers', these ships were intermediate between the 'thousand tonners' and the mass-production destroyers of World War One. Their characteristics essentially duplicated those of the earlier ships, but C&R proposed a new flush-deck hull form, to reduce rolling and pitching. Beam and midship cross-section both increased slightly, and draft had to be reduced in compensation. That in turn would have reduced hull depth (hence strength) in a conventional broken-forecastle hull; C&R solved the problem by increasing freeboard amidships, so that hull scantlings (hence weight) could beheld down. The designers hoped that dryness could be preserved, since the bow freeboard of earlier ships was retained. In practice, however, the flush-deckers were far wetter than their predecessors. Shallow draft also meant that the propellers would not be deep enough, and the ships had to be designed with a drag, ie with a keel sloping aft.

    Steam Engineering proposed a new triple-screw power-plant, the centre shaft being driven by the high-pressure turbine, with a geared cruising turbine clutched to it. The sketch design also showed three rather than four funnels, the two inner ones being trunked together. In practice, however, only the two Cramp ships followed the original design. The other four had twin screws (with Curtis geared turbines in DD 69, Parsons geared turbines in the others). Only the two Cramp ships and the Gwin had triple funnels. Unlike the mass-production 'flush-deckers', these ships had cutaway (vice cruiser) sterns.
