USCGC Point Caution (WPB-82301)
USCGC ''Point Caution'' (WPB-82301) was the first USCG Point class cutter constructed at the Coast Guard Yard at Curtis Bay, Maryland. She was built and commissioned in 1960 for use as a law enforcement and search and rescue patrol boat. Since the Coast Guard policy in 1960 was not to name cutters under in length it was designated as ''WPB-82301'' when commissioned and acquired the name ''Point Caution'' in January 1964 when the Coast Guard started naming all cutters longer than .〔(Coast Guard Historian website )〕〔Scheina, p 72〕
==Construction and design details==
''Point Caution'' was built to accommodate an 8-man crew.〔Scheina, p 71〕 She was powered by two VT600 Cummins diesel main drive engines and had two five-bladed propellers. The main drive engines were later replaced by VT800 Cummins engines. Water tank capacity was and fuel tank capacity was at 95% full.〔〔Scheina, p 71〕 Engine exhaust was ported through the transom rather than through a conventional stack and this permitted a 360 degree view from the bridge; a feature that was very useful in search and rescue work as well as a combat environment.〔Scotti, p 165〕
The design specifications for ''Point Caution'' included a steel hull for durability and an aluminum superstructure and longitudinally framed construction was used to save weight. Ease of operation with a small crew size was possible because of the non-manned main drive engine spaces. Controls and alarms located on the bridge allowed one man operation of the cutter thus eliminating a live engineer watch in the engine room.〔Scotti, p 165〕 Because of design, four men could operate the cutter; however, the need for resting watchstanders brought the crew size to eight men for normal domestic service.〔Scotti, p 165〕 The screws were designed for ease of replacement and could be changed without removing the cutter from the water. A clutch-in idle speed of three knots helped to conserve fuel on lengthy patrols and an eighteen knot maximum speed could get the cutter on scene quickly.〔Scotti, p 166〕 Air-conditioned interior spaces were a part of the original design for the Point class cutter. Interior access to the deckhouse was through a watertight door on the starboard side aft of the deckhouse. The deckhouse contained the cabin for the officer-in-charge and the executive petty officer.〔Scotti, p 166〕 The deckhouse also included a small arms locker, scuttlebutt, a small desk and head. Access to the lower deck and engine room was down a ladder. At the bottom of the ladder was the galley, mess and recreation deck. A watertight door at the front of the mess bulkhead led to the main crew quarters which was ten feet long and included six bunks that could be stowed, three bunks on each side. Forward of the bunks was the crew's head complete with a compact sink, shower and commode.〔Scotti, p 166〕 Accommodations for a 13-man crew were installed for Vietnam service.〔〔Scheina, p 72〕〔Scotti, p 10〕〔Scotti, p 219〕
