The US has passed a law requiring operators of recreational vessels less than 26 feet in length to use an engine cut-off switch (ECOS) and associated link (ECOSL). These are commonly known as kill switches.
The ECOS and ECOSL prevent runaway vessels and the threats they pose. The ECOSL attaches the vessel operator to a switch that shuts off the engine if the operator is displaced from the helm. The ECOSL is usually a lanyard-style cord that attaches to an ECOS either in close proximity to the helm or on the outboard motor itself if the vessel is operated by a tiller. When enough tension is applied, the ECOSL disengages from the ECOS and the motor is automatically shut down. Wireless ECOS have recently been developed and are also approved for use. These devices use an electronic “fob” that is carried by the operator and senses when it is submerged in water, activating the ECOS and turning the engine off. Wireless devices are available on the aftermarket and are beginning to become available as manufacturer-installed options.
Section 503 of the Coast Guard Authorization Act of 2018 required manufacturers of covered recreational vessels (less than 26 feet in length, with an engine capable of 115 lbs. or more of static thrust) to equip the vessel with an ECOS installed as of December 2019. Owners of recreational vessels produced after December 2019 are required to maintain the ECOS on their vessel in a serviceable condition. It is recommended that recreational vessel owners regularly check their existing ECOS system to ensure it works properly, following the manufacturer’s instructions.
Section 8316 of the Elijah E. Cummings Coast Guard Authorization Act of 2020 requires individuals operating covered recreational vessels to use ECOS “links” while operating on plane or above displacement speed. Using the ECOSL is not required when the main helm is installed within an enclosed cabin. Common situations where ECOSL use would not be required include docking/trailering, trolling, and operating in no-wake zones.
