USS PT-96, built by Huckins at Jacksonville, Florida, underway at high speed, circa 1942. Huckins Yacht Corporation built PT boats for two squadrons during World War II. In 1940, three governing bodies – the Bureau of Ships, the Board of Inspection and Survey, and the Navy Personnel Command – had agreed that all PT boats developed up to that time were defective.
In-water cleaning, also known as in-water surface cleaning, is a collection of methods for removing unwanted material in-situ from the underwater surface of a structure.. This often refers to removing marine fouling growth from ship hulls, but also has applications on civil engineering structures, pipeline intakes and similar components which are impossible or inconvenient to remove from the ...
A diver at work on hull maintenance. Ships husbandry or ship husbandry is all aspects of maintenance, cleaning, [1] and general upkeep of the hull, rigging, and equipment of a ship. It may also be used to refer to aspects of maintenance which are not specifically covered by the technical departments. [2]
The manufacturing rights were later purchased by John Althouse with the intention of restarting production. No new boats are currently being manufactured.

The buildup of biofouling on marine vessels poses a significant problem. In some instances, the hull structure and propulsion systems can be damaged. [3] The accumulation of biofoulers on hulls can increase both the hydrodynamic volume of a vessel and the hydrodynamic friction, leading to increased drag of up to 60%. [4]
