She also has two hydrographic winches, each of which can deploy 3,600 meters (11,811 feet) of 9.5-mm (3/8-inch) EM cable, two trawl winches, each of which can deploy 4,300 meters (14,107 feet) of cable, and a Gilson winch. She has a 60-foot (18.3-meter) telescopic boom with a lifting capacity of 6,250 pounds (2,835 kg) aft and a 23-foot (7-meter) fixed boom with a lifting capacity of 1,000 pounds (454 kg) at her bow. She has an A-frame on her starboard side with a safe working load of 8,050 pounds (3,651 kg) and a large A-frame aft. The oceanographic winch and large after A-frame work in conjunction to serve her stern sampling station, while the two hydrographic winches work with the side A-frame to service her side sampling station, and the two hydrographic winches together give "Oscar Dyson" the capability to have two scientific packages ready for sequential operations. In addition to trawling, her sampling stations can deploy smaller sampling nets, longlines, and fish traps. The hydrographic winches can deploy CTD instruments to measure the electrical conductivity, temperature, and chlorophyll fluorescence of sea water. "Oscar Dyson" also can deploy specialized gear such as Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) frames, towed vehicles, dredges, and bottom corers, and she can deploy and recover both floating and bottom-moored sensor arrays. "Oscar Dyson" has various laboratory capabilities. A wet laboratory, a dry laboratory, a biology laboratory, and a hydrographic laboratory all are situated on the starboard side of her main deck, while an electronics and computer laboratory are on the port side of her main deck. Her wet laboratory includes a climate-controlled space with a built-in chiler system. "Oscar Dyson" carries two boats. Her 27-foot (8.2-meter) survey launch has a 260-horsepower (194-kW) motor and can accommodate up to eight people. Her 22-foot (6.7-meter) rescue boat has a 256-horsepower (191-kW) motor and can carry up to six people. Designed for operations in Alaskan waters, "Oscar Dyson" has an ice-strengthened welded-steel hull.
