What was the top speed of the PT boat?
What was the top speed of the PT boat?
With a full loaded weight of 56,000 pounds, C-378 made a top speed of 37 kn (69 km/h; 43 mph) with 1,400 horsepower (1,000 kW), and maintained an average speed of 34.5 kn (63.9 km/h; 39.7 mph) in a winter northeaster storm with 12-to-14-foot (3.7 to 4.3 m) seas, which would still be considered exceptional even 100 years later.
What causes steering wheel to shimmy at certain speeds?
Steering wheel shimmy or vibration that occurs only at certain speeds is often related to dynamic imbalance in the tires, wheels, or axles.
Are there any of the PT boats still in use?
Two of the experimental PT-Boats also still survive, PT-3 (built by Fisher Boat Works) in New Jersey and PT-8. PT-3 was designed by George Crouch and employed lightweight planing hull construction methods.
Who was the final competitor for the PT boat?
The final PT boat design competitor was Huckins Yacht Corporation of Jacksonville, Florida. On 11 October 1940, an agreement between the Navy and Huckins was finalized. The Navy would provide engines, and Huckins would build a PT boat at their own expense, with the caveat that the boat (upon completion) would be offered to the Navy for a later sum.
