Miss England II was the name of the second of a series of speedboats used by Henry Segrave and Kaye Don to contest world water speed records in the 1920s and 1930s.

Miss England II was built for Lord Wakefield in 1930, who had obtained a pair of new Rolls-Royce type R V-12 air-racing engines. Mounted aft of the cockpit, they turned a single propeller shaft via a gearbox mounted near the bow. The shaft ran aft below the hull to a twin-bladed screw, first of 11.75 inches diameter and later, in trials, of 9 inches.

The stepped hull design was similar to that of the previous Miss England. On Miss England II, the step was separate from the hull, so that with the boat withdrawn from the water it could be unbolted and moved fore or aft to balance the boat for speed.

The cockpit accommodated a crew of three, with engineer and mechanic in the left and right seats and driver amidships.

On Friday 13 June 1930, Segrave drove Miss England II to a new record of 98.76 mph (85.82 kn; 158.94 km/h) average over two runs on Windermere. On a third run the boat, which is presumed to have hit a floating branch, capsized at speed. Chief engineer Victor Halliwell, at the "low" side of the boat as it turned over on top of him, was killed. His mechanic, Michael "Jack" Willcocks, thrown clear from the 'high' side of the boat, survived with a broken arm. Segrave, who was rescued unconscious as the boat sank, regained consciousness for a moment and asked about the fate of "his men". Shortly after being told that he had broken the record, he died from lung injuries. Concerns were raised that the boat's hull was too light in design and construction, particularly around the hydroplane's step, which was found to have partially detached.

An early theory that the step had failed as the boat passed over its own wake from a previous run was discounted after a waterlogged branch showing recent impact damage drifted ashore some thirty minutes after the accident.

Following Segrave’s death, Miss England II was salvaged and repaired, and Kaye Don was again chosen as the driver for 1931. Early that year, Don tested the boat on Lough Neagh, near Belfast, Northern Ireland, and reached an unofficial speed of 107mph.Garfield Wood then established the official record at over 100 mph (87 kn; 160 km/h). A month later, on Lake Garda, Italy, Don raised it to 110.28 mph (95.83 kn; 177.48 km/h). In February 1932 Wood raised it again, by 1 mph (0.87 kn; 1.6 km/h).
