T-47 Class Torpedo-Boat
Advances in engine technology allowed for a 20% increase in powerplant output in the basic T-37 hull. This provided a whopping one knot of additional speed. Freeboard is also slightly increased.
This class also works with the fleet.
Note that I'm paying 0.414 BP for T-57 and onward, for reasons my spreadsheet does not explain. Oh well.
