The Type II Hunts are listed with 19,000 shaft horsepower for 27 knots, while the similarly sized Egret-class sloops are listed with 3,600 shaft horsepower for 19.25 knots. Both used the same pattern of geared steam-turbine system, although the Hunts were slightly longer and required far more power for their higher speed. The comparison raises a question about how treaty speed limits, official ratings, hull design, and actual machinery potential interacted in British sloop design. No surviving original turbines can be tested to settle the issue. This watch point keeps the engineering question open instead of turning suggestive figures into a firm performance claim.

Hunt and Egret machinery raise a treaty-speed question
Similar hull sizes and reportedly related turbine systems make the large published power gap between Hunt destroyers and Egret sloops a provocative but unresolved treaty-era engineering question.
