The USCGC Matagorda (WPB-1303) was an Island-class patrol boat built for the United States Coast Guard, commissioned on April 24, 1986. Constructed by Bollinger Shipyard in Lockport, Louisiana, it originally measured 110 feet in length, based on the design of the highly regarded Vosper Thornycroft 33-meter patrol boats from Great Britain, serving as a replacement for the older 95-foot Cape-class cutters. As part of the Coast Guard’s modernization efforts, the Matagorda was later modified under the Deepwater System Program, which aimed to extend its operational life and upgrade its capabilities. In 2004, the Matagorda was among eight vessels selected for a significant refit that included lengthening the hull by 13 feet to add a high-speed launching ramp, replacing the superstructure to support mixed-gender crews, and installing new electronics, communication systems, and upgraded berthing and galley facilities. These modifications transformed the vessel from an Island-class patrol boat into a more versatile, blue-water capable platform, with the added length increasing displacement by approximately 15 tons and reducing maximum speed by roughly one knot. However, the Deepwater modifications encountered serious issues. During sea trials in September 2004, the Matagorda was forced to conduct a high-speed transit to evade Hurricane Ivan, operating at around 24 knots in Sea State Five conditions. Post-trial inspections revealed severe structural problems: buckling of the side and main deck near midships, cracking of hulls, and hull breaches. These problems worsened over time, with cracks and hull deformation leading to leaks, misaligned propeller shafts, steering difficulties, and compromised systems such as waste disposal and communications. The extensive workmanship deficiencies and poor welding practices contributed significantly to the hull failures. By late 2006, the Coast Guard deemed the vessels unseaworthy and ordered their decommissioning. The Matagorda and its sister ships were towed to the Coast Guard Yard at Curtis Bay, Maryland, where they remain in a mothballed state. The failed Deepwater conversion program resulted in costly legal actions, including lawsuits against Bollinger Shipyards, which paid settlements for damages related to these vessels. The overall efforts to modernize the 110-foot cutters were halted, emphasizing the importance of quality in maintenance and the challenges faced by aging patrol fleets. The Matagorda’s troubled history highlights the complexities and risks associated with ship conversions and upgrades in maritime operations.
