A tether may be the single most important pieces of safety gear for coastal and offshore sailors and singlehanders. Few boating hazards are greater than being separated from the boat. Adding a tether to your lifejacket transforms it into a full-featured piece of safety equipment that helps ensure you remain aboard in all conditions provided your harness is clipped to a jackline. An elastic tether allows the greatest freedom of movement and improved safety, as it expands to accommodate your on-deck movement and contracts to stay out of your way, making it the tether of choice for boaters who wear a harness/tether combination regularly.
The ISAF/ORC tether is a single elastic tether with two double-action safety hooks. It extends to 6.6' (2m). With a built-in overload indicator, it complies with ISAF/ORC specifications. When the tether is subject to a heavy load, such as a person overboard, the overload indicator exposes a label indicating that the tether should be replaced.
