1/2 Inch Double Swivel, Part No. AKSTS-1/2, is a popular item where stabilizers are used for anchoring. A line from the vessel to the swivel keeps the cable from twisting and snarling.
The Kolstrand double swivel is also very helpful when cruising. By having a line from the bow of the vessel to the swivel helps the stabilizer from lagging back too far.
All Kolstrand stabilizers are manufactured with steel-galvanized and stainless steel materials for long-life in the marine environment.
