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 . Construction and design details. "Point Caution" was built to accommodate an 8-man crew. 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. 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. 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. 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. 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. 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. 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. Accommodations for a 13-man crew were installed for Vietnam service. History. After delivery in 1960, "Point Caution" was assigned a homeport of Galveston, Texas, where she served as a law enforcement and search and rescue patrol boat. At the request  of the United States Navy, in April 1965, she was alerted for service in South Vietnam and assigned to Coast Guard Squadron One in support of Operation Market Time along with 16 other Point class cutters. While the crew completed overseas training and weapons qualifications at Coast Guard Island and Camp Parks, California, "Point Caution" was loaded onto a merchant ship, and transported to Subic Bay, Philippines in May 1965 where she was refitted for combat service. Shipyard modifications included installation of new single-sideband radio equipment, additional floodlights, small arms lockers, additional sound-powered phone circuits, and the addition  of four M2 machine guns. The original bow-mounted machine gun was replaced with a combination over-under .50 caliber machine gun/81mm trigger-fired mortar that had been developed by the Coast Guard for service in Vietnam. For service in Vietnam, two officers were added to the crew complement to add seniority to the crew in the mission of interdicting vessels at sea. "Point Caution" was assigned to Division 12 of Squadron One to be based at Da Nang, along with , , , , and . After sea trials, the Division left Subic Bay for Da Nang on 16 July 1965 in the  company of , their temporary support ship. After almost two weeks at sea, they arrived at their new duty station on 20 July and began patrolling the coastal waters near Da Nang. Duty consisted of boarding Vietnamese junks to search for contraband weapons and ammunition and check the identification papers of persons on board. Permanent engineering and logistic support of Division 12 was provided by a U.S. Navy non-self-propelled floating workshop, YR-71. During this time, the WPB's were directed to paint the hulls and superstructures formula 20 deck gray to cover the stateside white paint. This increased the  effectiveness of night patrols. On 29 April 1970, "Point Caution" was turned over to the Republic of Vietnam Navy as part of the Vietnamization of the war effort and recommissioned as RVNS "Nguyễn An" (HQ-716).
