Damage Points: 2	In Service: 1941
Damage Modifier: .75	Speed: 41
Propulsion: Petrol	Crew: 12
Armor Rtng: 0	Size Class: E

Remarks:
Wooden hull. Within a few months of service at top speed for a vessel would drop dramatically because of bottom fouling, added weight from water soakage, added enquipment, and general wear and tear on the engines. Before a game, the player controlling the PT boats should roll 2D6 for each boat and subtract this number from the top speed of that boat. Many possible armament variation. On any boat the aft two torpedo tubes can be replaced by 2 DC racks each with with 4 Mk6 DC. PT 22, 24, 26, 27, 45-48, and 59-68 fitted with A(1)4 Mk4 20mm (Lt AA=.5)

Wooden hull. Within a few months of service at top speed for a vessel would drop dramatically because of bottom fouling, added weight from water soakage, added enquipment, and general wear and tear on the engines.

Movement restrictions before firing are removed, but the mount still rolls to hit like a gun in local control. Gun configuration as built (2)2 .50 cal, A(1)1 Mk4 20mm.
