About 160 marine craft were built by PBI in the 1960's, many for the US Navy, varying from wooden minecraft to aluminum gunboats to fiberglass personnel boats. PBI continued its dominance in the construction of wood hull minesweepers, building four 110' MSI's and twenty-one 145' MSC's. PBI constructed thirty-nine aluminum hull gunboats ranging from 95' to 165' and numerous smaller craft such as utility boats, oceanographic boats, torpedo retrievers and tug boats.

During the 1970's, PBI performed a wide variety of commercial construction projects including some of the largest ships built by PBI. These projects included two 300' heavy lift ships, several oceanographic research ships and boats, tuna seiners from 225' to 262' in length, car/passenger ferries, fire and rescue boats and a variety of tug boats. PBI also continued its Navy tradition, building thirteen YTB tug boats and nine 190' PGG gunboats for the Saudi Navy.
