The sister ships Kalvik and Terry Fox, built in the Victoria and North Vancouver yards, respectively, of the Burrard Yarrows group and delivered to Gulf Canada Resources for 1983 Beaufort Sea operations, are high-powered twin-screw Arctic Class 4 anchor-handling tug/supply vessels. The hull is of double-chine fully-developable form, and there is a semi-spoon bow and a forward ice-plough; the bow is designed to maximise both level-ice and ridge-penetration performance.

Other features mentioned in the article include a large rudder, with steering assisted by 500-hp stern thruster and an air-bubbler system which can be used as a bow thruster. Principal particulars are: length 88m o.a.; moulded breadth 17.5m; depth 10m; draught 8m; 2200 dwt; four 5800-bhp Stork-Werkspoor TM 510 main engines, each pair geared to drive an open c.p. propeller, with a 1000-kW generator clutched off each of the two gearboxes <there are also two 750-kW generator sets>; trials speed 15.6 knots; complement 18 crew <in single cabins> plus 16 supernumeraries <two to a cabin>; built to LR highest class and other requirements, as approved by Canadian Coast Guard.
