HMS Speedwell (J87) was a Halcyon-class minesweeper launched in 1935, renamed Topaz and sold into civilian service in 1946'.
Speedwell, possibly a Revenue cutter or a privateer, captured two French privateers in early December 1782 near Weymouth. One was Complaisant, and the other was Poisson Volant. This Speedwell does not appear to be HMS Speedwell as at that time the latter was at Gibraltar.
