The Fairmile Motor Launch was a kit-based wooden vessel built in many types: A-D and H. The FMLA was 57 tons and 25 knots with a crew of 12, sonar and a dozen depth charges. The FMLB was 85 tons, 20 tons, 16+ crew, and armed with a 3-pounder gun, sonar, and depth charges. The FMLC was a 26.5 knot motor gunboat with a couple of 2 pounder guns and 4 depth charges. The FMLD was an MTB (29 knots) and a mix of weaponry. The H was a landing craft (15 knots).
There were also Harbour Defence Motor Launches--54 tons, 10 crew, 12 knots, 2x20mm, 6 DCs.
According to the history of operations into Norway from the Shetlands, the Coastal Forces of the RN particularly valued American subchasers. Most of these were 98 ton wooden vessels with 27 crew, 20 knots (12 knots cruising), a 3-inch gun, sonar and depth charges. They were responsible for sinking about 67 U-boats in coastal American waters and at least one RO-boat in the Pacific. They were hard for submarines to detect.
Correct me if I'm wrong, but all boats, whatever their designation are only 18 knots in game. Thus most subs can actually outrun them.
They could on the surface.
