Cargo capability
From June through November 1998, Cape Vincent and her sister vessel Cape Victory were modified by the addition of a new spar deck. This increased the overall militarily useful sq. ft capacity of each vessel. The two CAPE V class ships function the same in their ability to load wheeled and tracked vehicles via the stern ramp. Cape Vincent's most notable feature is its total deck capacity consisting of 156,524 square feet (14,541.6 m2), of which 126,084 is militarily useful. Cape Vincent has 126,084 sq ft of heavy deck strength (over 525 psf with 13 f. clearances) and 30,440 sq ft of light deck. In addition, Cape Victory has 100 450-volt reefer outlets.
Operations
Within one month of entering the RRF, on 9 September 1994, the Cape Vincent loaded cargo at Wilmington, North Carolina, and departed for Port-au-Prince, Haiti. Cape Vincent supported Operation Uphold Democracy, a peace-keeping mission, for 104 days before returning to Beaumont, Texas.
Following her return from Uphold Democracy she returned to her layberth and was next activated on 25 December 1994, for Fuertas Defensas 95, providing 45 days of transport for outsized unit equipment to Guatemala in support of military training. This was part of a larger exercise which included the Army's Battlefield Visualization initiative in Panama.
On 4 September 1996, Cape Vincent underwent a test of her activation readiness capability and successfully activated in 1.9 days. Cape Vincent surpassed this record, activating in 1.8 days for a humanitarian relief effort to Central America in response to the damage caused by Hurricane Mitch. Cape Vincent transported construction equipment and relief supplies for 108 days. On 30 March 1999, Cape Vincent received the Maritime Administrator's Professional Ship Award in recognition of her service.
The Cape Vincent was activated on 17 January 2003 for Operation Iraqi Freedom and loaded cargo from the 4th Infantry Division at the Port of Beaumont. The ship spent a total of 118 days in Full Operating Service (FOS), discharging cargo in Kuwait, loading in Turkey, discharging in Rotterdam and returning to Beaumont on 16 May 2003. Cape Vincent was active moving military equipment to Kuwait and back until the latter part of 2008. In 2005, Cape Vincent was on charter to FEMA providing relief to victims of Hurricane Katrina in New Orleans. Cape Vincent is located in the Beaumont Reserve Fleet in Reduced Operating Status with a crew of 10. operated by Keystone Shipping until Jan 2016. Patriot Contract Services took over operations in February 2016.
Cape Vincent moved to the Marad Reserve Fleet in Beaumont, Texas, in August 2009 along with her sister ship Cape Victory, saving the US Government approximately $1 million per year.
