Well, imagine a beautiful sunset painting where the colors blend together perfectly. PT boats were like those colors in the war, blending in to surprise the enemy with their speed and agility. They helped change the course of the war by being quick and nimble, able to strike fast and vanish just as quickly, like happy little clouds in the sky.

John Kennedy was noted for his PT boat service in WW II.
Patrol Torpedo Boat
Navy PT boats would place upside-down brooms on their masts upon returning from missions to signal that they had completed their operations and were back in port. This practice served as a visual notification to other vessels and personnel that the boat was returning safely and was not in a state of distress. It was a simple way to communicate and maintain safety in busy harbor environments.

At least 2, possibly 3 companies manufactured the wooden PT boats of WW2. Consequently their lengths varied in size, and so did their complement of crewmen. The average WWII PT boat was manned by about 2 or 3 officers and 12 to 14 crewmen. The Vietnam War Swift Boats (officially designated PCF-Patrol Craft Fast) are alot easier to address: only one company made them; Seward's out of Louisania. These were 50 footers, and all aluminum built; manned by 1 officer and 5 crewmen.
