Construction and design details
''Point Marone'' 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 Marone'' 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 theHistory
After delivery in 1962, ''Point Marone'' was assigned a homeport of San Pedro, California, 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.Cutler, p 84Larzelere, p 21 While the crew completed overseas training and weapons qualifications at Coast Guard Island and Parks Reserve Forces Training Area, Camp Parks, California, ''Point Marone'' 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, bunks, additional sound-powered phone circuits, and the addition of four M2 Browning machine gun, M2 machine guns. The original bow-mounted machine gun was replaced with a combination over-under .50 caliber machine gun/81 mm trigger-fired mortar that had been developed by the Coast Guard for service in Vietnam.Larzelere, p 21Cutler, p 82 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.Larzelere, p 15 ''Point Marone'' was assigned to Division 11 of Squadron One to be based at An Thoi Naval Base,Kelley, p 5-13 on the southern tip of Phú Quốc island along with , , , , , , and . After sea trials, the Division left Subic Bay for An Thoi on 17 July 1965 in the company of , their temporary support ship. After almost two weeks at sea, they arrived at their new duty station on 1 August and began patrolling the waters in the Gulf of Thailand near the Cà Mau Peninsula.Kelley, p 5-97Larzelere, p 48 Duty consisted of boarding Vietnamese junks to search for contraband weapons and ammunition and check the identification papers of persons on board. During September 1965, , a repair ship outfitted for the repair of WPB's relieved the ''Floyd County''. Also 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.Cutler, p 85 While on patrol in the Gulf of Thailand near the Cambodian border on the night of 19 September 1965 ''Point Marone'' intercepted a suspicious junk operating near Ha Tien and warned it to stop for boarding. After receiving fire from the junk she returned fire, and with assistance from ''Point Glover'' they sank the junk in of water. After the junk was recovered the following day, rifles, grenades, ammunition and documents were discovered. The only survivor of the crew of the junk provided intelligence which led to a raid on Hon Mot that was conducted on 26 September. ''Point Marone'' participated in the raid along with cutters ''Point Comfort'' and ''Point Grey'' by transporting Civilian Irregular Defense Group program, Civilian Irregular Defense Group (CIDG) mercenaries and their U.S. Army Special Forces, Special Forces advisors to the raid and providing fire support with the 81 mm mortar.Larzelere, p 45Cutler, p 110 On 4 August 1970, ''Point Marone'' and , conducted the last mission for Squadron One on the Co Chien River. The cutters each carried fifty Kit Carson Scouts and their ARVN advisors along with the full 13 man Republic of Vietnam Navy (RVNN) replacement crew aboard for their final check ride for the Vietnamization program. In one of the canals that intersected with the river ''Point Marone'' hit a command detonated mine wounding several on board and causing several holes below the waterline.Larzelere, p 226 The mission was cancelled and ''Point Cypress'' escorted her back to the base at Cat Lo Naval Base, Cat Lo.Larzelere, p 229 On 15 August 1970, ''Point Marone'' along with ''Point Cypress'' were turned over to the RVNN; the last two of the 26 Point-class cutters assigned to Squadron One. ''Point Marone'' was recommissioned as RVNS ''Trương Ba'' (HQ-725).Scotti, p 211References
