Class History:  

The 210-foot cutters were added to the Coast Guard as part of an effort to upgrade the aging fleet of World War II-era cutters.  The Coast Guard's Naval Engineering Division designed these cutters for search and rescue and law enforcement patrols of a "medium endurance"--i.e. they could conduct patrols of up to three weeks without requiring replenishment.   The outward appearance of these new cutters reflected the evolving nature of Coast Guard operations during the latter part of the 20th Century.  They had sleek lines with the most prominent feature being their flight decks.  They were originally fitted with transom exhaust ports that provided more room for a larger flight deck and kept the flight deck clear of exhaust smoke.  In practice, however, the exhaust system proved problematic.  Their high pilot house gave the bridge crew unrestricted all-around visibility, making ship-handling easier.  A number of other concerns figured into the design phase including maximum serviceability, improved habitability, long service life, and safety. 

Two shafts capped by controllable pitch propellers drove these cutters to a top speed of 18 knots.  Those shafts were powered by a number of different power plants.  The Coast Guard actually designed two types of propulsion.  Cutters 615-619 received a CODAG propulsion plant consisting of two Cooper-Bessemer Corporation FVBM-12 turbocharged diesel engines coupled with two Solar Aircraft Company gas turbines turbines, the first U.S. vessels to receive this unique propulsion system.  The other cutters received only the diesels.  The propulsion system could be remotely controlled from the pilothouse, either bridge wing, or the engine room control booth. 

Crew comfort and convenience were also a priority.  The Coast Guard actually hired the interior design firm Raymond Loewy Associates of New York to design the cutters' interior arrangement, colors, materials, furniture and appointments.  The interior spaces were paneled and all piping and cables were hidden behind removable panels.  The entire interior of the cutter was air conditioned for crew comfort.  Additionally, "color schemes have been designed to give varied and pleasing effect."  The recreation rooms included television sets, tape recording and playback equipment, AN/URR-44 radio receivers, and commercial AM/FM high fidelity radio receivers. These cutters were also designed to incorporate additional armament in case of national emergency.  This equipment originally would have consisted of: an additional 3-inch gun; a total of six .50 caliber machine guns with mounts;  an SQS-17 sonar (later suggestions included using a SQS-36); one anti-submarine projector (Hedgehog); two torpedo launchers and two depth charge tracks.  Space was included in the original design to incorporate the additional equipment although stability issues were a continual concern.  No cutter, according to the historical documents, was actually ever fitted with this wartime armament. 

Each cutter underwent a "Major Maintenance Availability process," or MMA, between 1986 and 1996 at a cost of between 19 and 21 million dollars per cutter.  The Coast Guard Yard conducted the work on all but two cutters and Colonna's Shipyard, in Norfolk, Virginia, converted the remainder.  The first five cutters traded in their unique powerplants and every cutter received the following modifications and upgrades: improved habitability, improved stability by rearranging tank locations, replacement of all asbestos paneling, increased the berthing space, upgraded the flight deck and helicopter equipment, increased the amount of helicopter fuel carried, improved the evaporator, increased and upgraded the communications and electronics capacities, installed vertical exhaust stacks and associated ballast, and installed a smoke detection system and new fire-fighting equipment.  

Cutter History:

Durable was the first cutter in Coast Guard history to hold this name.  Like all ships in the Reliance-Class of 210-foot medium endurance cutters, Durable was named for an aspirational trait meaning to be capable of withstanding wear or decay.

The Coast Guard Yard laid Durable's keel on 1 July 1966.  Mrs. Alton A. Lennon, the wife of Congressman Alton A. Lennon of North Carolina, sponsored the new cutter at Durable's christening and launching on 29 April 1967.  The Coast Guard commissioned Durable on 8 December 1968 at Coast Guard Base Galveston, under the command of CDR Richard M. Thomas.  She was initially home-ported at Galveston, Texas.  The following year, in June, 1969, she transferred to Brownsville, Texas, where she operated from until 1986.  On her first day of duty at Brownsville Durable assisted the grounded fishing vessel Dahlia 125 miles south of Galveston.  On 25 June 1969 CDR Paul E. Schroeder took command of the cutter.  In February and March of 1970 she monitored the situation following a fire on an oil rig off the entrance to the Mississippi River.  She sailed to the assistance of the shrimp trawler Mr. Tucker in December of 1970 after the trawler had been hijacked from the port of Freeport, Texas.  The trawler's crew killed the two hijackers and then requested assistance.  The Durable towed her back into port.

In March of 1972, under the command of CDR William Drew, she acted as the on-scene commander for the multi-unit search for survivors of the T/V San Nicholas which had broken in half and sank on 5 March.  During this operation, a Coast Guard HH-52A became the 1,000th helicopter to make a successful landing on Durable's flight deck.  On 15 March, while still acting as the on-scene commander, she responded to a medical emergency on board the M/V Constellation.  A passing merchant ship managed to save two survivors of San Nicholas, but all the cutter found was debris.  In October of 1973 Durable, now under the command of CDR William J. Brogdon, Jr., responded to a distress call from the F/V Tiki 7, which was disabled and in danger of sinking.  The cutter arrived to find the vessel nearly submerged.  She rescued her seven crewmen and marked the vessel as a hazard to navigation.

In 1975 Durable accomplished one of the longest tows on record.  The tug Beaver became disabled while towing two decommissioned U.S. Navy destroyers to a scrap yard.  With a tropical storm approaching the three vessels, Durable was sent to the rescue.  Arriving on scene, the cutter made up a 3,500 foot towline and fought 50-knot winds and 12-foot seas while towing all three vessels to safety.

During the first six months of 1978, Durable saved six lives and one vessel while assisting 26 other people.  Although search and rescue was always one of the Coast Guard's primary missions, during the mid-1970s and on the Coast Guard's efforts to interdict narcotics smuggling by sea became a focus of the Coast Guard and Durable's history reflects that shift.  During this same six month period, she gained international attention for her law enforcement activities that overshadowed this successful search and rescue work.

On 6 December 1977 she seized the M/V Lemarca I after a boarding party discovered 55,060 pounds of marijuana on board and arrested her 9-man crew.  On 4 May 1978 she seized the F/V Pappy with 31,772 pounds of marijuana on board and arrested her 5-man crew.  On 3 June 1978, with a television news crew aboard who were filming the cutter's enforcement of fisheries laws, she seized the F/V Adeline Marie after discovering 49,400 pounds of marijuana on board.  Her three-man crew was taken into custody and the television crew captured the entire event on camera and Durable and her crew were soon on the evening news.

The following month Durable, now under the command of CDR Gary F. Crosby, set a personal record of seizures that again made the local media.  On 5 July 1978 she seized the Bonos Margie after discovering 26,912 pounds of marijuana on board and arrested her six-man crew.  Later that month, on 12 July, she seized a 63-foot dive boat 200 miles southwest of Key West, Florida, after her helicopter located the suspect craft and a boarding team discovered 1,000 bales of of marijuana in the dive boat's hold.  After taking the vessel's occupants into custody and placing a prize crew aboard, the cutter got underway, escorting the vessel, bound for St. Petersburg.  

En route, she came across the sport fisherman Miss Renee, boarded her and discovered over 17,000 pounds of marijuana.  She seized that vessel and began escorting both back to Florida.  Later that day she came across the 65-foot F/V Joanne, located 20,148 pounds of marijuana on board, and seized her.  Fifty-five miles south-southwest of St. Petersburg she located the 40-foot yawl Carte Blance, boarded her, and discovered 15,396 pounds of marijuana.  The Durable seized her as well and escorted all four of the arrested vessels to St. Petersburg.  During her patrol, she conducted 37 helicopter landings, bringing her total since commissioning to 2,806.

After returning to the Gulf of Mexico, she seized the 111-foot coastal freighter Superfly II on 16 August 1978 when a boarding party located over 32 1/2 tons of "high-grade Columbian" marijuana on board.  Her 16-man crew was taken into custody and a prize crew was placed on board.  The cutter then escorted her prize back to Brownsville, arriving there on 19 August 1978.  For the period of 6 December 1977 through 31 August 1978, she seized nine vessels and 311,000 pounds of marijuana.  In recognition of her outstanding performance in both search and rescue and law enforcement activities during the period from December 1977 through August 1978, the commander of the Atlantic Area, VADM R. T. Price, awarded the cutter and crew the Coast Guard Meritorious Unit Commendation.

From December 1978 to August 1979, she inspected the entire fleet of Japanese tuna long-line fishing vessels that sailed in the Gulf of Mexico.  She issued citations and notices of violations.  She also continued her narcotics seizures.  On 22 April 1979 she seized the F/V Cap'n Stud after discovering 15,000 tons of marijuana, however, the vessel and cargo were destroyed while hard aground on a reef.  

CDR Kent H. Williams took over command of the cutter in June of 1979.  On 12 July 1979 she seized the F/V Morning Star, which was attempting to smuggle 25,000 pounds of marijuana.  Also in July, Durable responded to a distress call from the M/V Maritime Hawk which reported having a fire in her engine room.  The cutter arrived within two hours and assisted the Maritime Hawk's crew in successfully fighting the fire.  

On 19 April 1980 Durable suffered a fire in her engine room.  On 7 November 1980 she seized the F/V Liebre which was carrying 20,000 pounds of marijuana.  A year later, on 18 November 1981 Durable seized the F/V Miss Karline which was attempting to smuggle 13,600 pounds of marijuana and arrested her crew of 11.  On 10 January 1982 Durable seized the F/V Windjammer, which had 16,000 pounds of marijuana on board.  All six of her crew were arrested.  On 15 January 1982 she seized the Carolina / Mary Ann I, which had a record 47,000 pounds of marijuana on board.  Her six-man crew was also taken into custody.  The following year, on 25 September 1982,  she seized two U.S. fishing vessels, the Don Manuel and the Brownskin Gal, off the Yucatan Peninsula carrying 13 tons of marijuana.  All 11 crewmen were arrested. 

On 13 May 1983 she seized Afcog VI / Blanquita carrying 30,000 pounds of marijuana.  Later that year, on 13 September, she seized the F/V Macabi, which was carrying 22,750 pounds of marijuana.  On 5 February 1984 she seized the 70-foot vessel Lady Mar in the Yucatan Channel after a 20-hour chase in which Lady Mar rammed Durable twice in an attempt to prevent a boarding.  The Durable sustained minor hull damage but managed to seized the vessel.  Her boarding team discovered over 43,000 pounds of marijuana.  Again in the Yucatan Channel, on 27 March 1984, she seized the F/V Lady Linda attempting to smuggle 30,960 pounds of marijuana.  

In May of 1985 she seized two fishing vessels for narcotics violations.  On 5 May she seized the F/V Miss Ruth, which was carrying 25,560 pounds of marijuana and four days later, on 9 May, she seized the F/V Fenix which was carrying 24,960 pounds of marijuana.  The latter, a Columbian-flagged vessel, was boarded after permission was obtained from the Columbian government.  Both crews, totaling 17 men, were arrested and the vessels were escorted to Key West.  On 5 November 1985 she seized the Mexican F/V Don Jose which was carrying 24,000 pounds of marijuana.  The vessel was found abandoned and sinking while at anchor -- Durable's crew managed to "interdict" the illicit cargo before she sank.  On 12 March 1986 she attempted to stop and board the Mexican F/V Fermin II, but her crew scuttled the fishing vessel.  Five persons on board were rescued and then arrested and evidence was obtained.  Both the evidence and the five persons on board were turned over to the Mexican Navy.

On 4 May 1986 Durable seized the F/V San Juan, which had 19,760 pounds of marijuana on board, and arrested her crew of 7.  On 16 May 1986 a boarding party discovered approximately 200 tons of marijuana aboard the sailing vessel West Wind.  The West Wind was seized and her crew of three were taken into custody.  On 14 July 1986 she seized the Columbian-flagged F/V Oniris on behalf of the Columbian government and arrested her crew of 7.  On 18 July 1986 a boarding team found marijuana residue on board the M/V Halley.  They then seized the vessel and arrested her crew of 6.

The Durable was then prepared to undergo a $28 million refit known as a "Major Maintenance Availability."  She was decommissioned in the fall of 1986 after steaming to Colonna's Shipyard in Norfolk, Virginia.  The refit included improving habitability, improving stability by rearranging tank locations, replacement of all asbestos paneling, increasing the berthing space, upgrading the flight deck and helicopter equipment, increasing the amount of helicopter fuel carried, improving the evaporator, increasing and upgrading the communications and electronics systems, and adding a new smoke detection system and fire-fighting equipment.  The most obvious change, however, was the removal of her problematic stern exhaust system and its replacement with traditional vertical exhaust stacks.  

The overhaul was completed by 30 January 1989 and Durable returned to active service on 25 May 1989 under the command of CDR Anthony S. Tangeman.  She was home-ported in St. Petersburg, Florida, for the remainder of her Coast Guard career.  For the remainder of her Coast Guard career, Durable, along with all units based in D7 and D8, were frequently called upon to intercept illegal migrants attempting sea passage to the U.S. from islands in the Caribbean, in particular Cuba and Haiti.

After a military coup occurred in Haiti on 30 September 1991, 15 U.S. and two French missionaries left the island nation on 8 October aboard three sailboats, bound for Guantanamo Bay [GITMO], Cuba.  After receiving a request for assistance through the U.S. Embassy in Paris, France, the Coast Guard sent a HU-25 Falcon to locate the three vessels, which were found 60 miles south of GITMO.  The jet then vectored Durable, then at GITMO on a mid-patrol break, to the scene.  Once she arrived, the cutter established communications with each of the three sailboats.  The missionaries passed the word that many of them were seasick and suffering from exhaustion.  Those so afflicted were transferred to the cutter and two-men crews from Durable were placed aboard each of the sailboats to assist the remaining passengers in sailing the vessels.  Early the next morning two of the three boats developed mechanical problems.  The cutter took one under tow while Durable's engineers repaired the other.  She then set a course back to GITMO, towing one sailboat and escorting the other two.  

In May of 1992 Durable, along with Nantucket (WPB-1316), participated in Operation Tradewinds '92, a joint exercise involving U.S. forces and units of the Lesser Antilles Regional Security System (RSS).  The Coast Guardsmen trained local coast guard forces in search and rescue techniques, damage control, navigation, gunnery operations, and maritime law enforcement tactics.  The Durable, under the command of CDR R. W. Batson, made ports of call in Barbados, Bahamas, Jamaica, Grenada, St. Vincent, Trinidad, St. Lucia, St. Kitts, Antigua, and Dominca.  In a sign of things to come, she intercepted a number of Haitian vessels attempting to make it to U.S. soil and turned them back to Haiti while those on vessels found to be unseaworthy were taken aboard and dropped off at GITMO.

In 1992 and 1993, increasingly large numbers of Haitians set sail for the U.S. in a wide variety of craft.  The Coast Guard, under the operational rubrick "Able Manner," attempted to halt that flow of desperate humanity.  The Durable, on a fisheries enforcement patrol in the Gulf of Mexico, was ordered to the waters off the north coast of Haiti.

In May of 1995 Durable intercepted 13 Cubans migrants and took them aboard.  Under a policy established by President William J. Clinton whereby any Cuban migrants picked up at sea would be returned to Cuba, Durable sailed to the Cuban port of Cabaņas.  She arrived there on 9 May 1995, becoming the first vessel of the U.S. government to dock in a port under the control of the Cuban government in some years. 

On 2 January 1996 Durable rescued 195 Haitians who were on board a grossly overloaded 50-foot sailboat when she was intercepted northwest of Haiti.  The Haitians were returned to Port-au-Prince.  On 8 September 1996 she seized the M/V Solution after a boarding party discovered approximately 14 kilos of cocaine on board.  On 21 February 1997 Durable, under the command of CDR Stephen J. Krupa, returned to St. Petersburg after a 49-day patrol that covered over 9,000 miles through the Caribbean.  During that patrol the cutter conducted three search and rescue missions and took custody of the 173-foot Honduran freighter Gold Star after the Coast Guard Law Enforcement Team 8H assigned to the USS Clark (FFG-11) discovered 1,000 pounds of cocaine aboard the vessel.  The Confidence (WMEC-619) first took custody of the seized freighter and began towing her to Florida.  The Durable rendezvoused with Confidence, put an eight-man custody crew aboard the M/V Gold Star, took the vessel under tow and sailed to Key West.

On 23 March 1997 Durable seized a 32-foot speedboat carrying 1,600 pounds of cocaine while the cutter was on a 41-day patrol of the Caribbean.  A Coast Guard HC-130 spotted the boat near Haiti and directed Durable to the intercept.  The speedboat managed to ground on a beach and its crew escaped inland, but the cutter seized the craft and its illicit cargo.  

Later that year Durable, under the command of CDR J. P. Benvenuto, conducted a 51-day, 9,000-mile patrol, returning to St. Petersburg on 27 September 1997.  During the patrol Durable participated in operation "Caribe Venture," a cooperative law enforcement operation in the eastern Caribbean.  The operation involved forces from the U.S., Great Britain, Antigua, Bermuda, St. Lucia, St. Vincent, Dominica, St. Maarten, Barbados, Grenada, and the Netherlands.  In December of 1997, during a 50-day patrol of the Caribbean, Durable recovered eight bales of marijuana that were dumped overboard from a "go-fast" boat that the cutter had been chasing.  The boat managed to evade capture.

Due to the "increasing age of the deepwater fleet after 30 years of service, and due to mounting, costly maintenance requirements," the Durable was scheduled for decommissioning.  The Coast Guard decommissioned the venerable cutter on 20 September 2001.  In 2003 she was transferred to the government of Columbia.
