After WWII, PT-305 acted as a civilian tour boat in New York Harbor and a fishing charter, while falling into disrepair. The New Orleans museum purchased the boat in 2007 and since then, a volunteer team of 202 people worked 105,000 hours at its restoration pavilion to get PT-305 back up and running.
