Wrapping It Up
There are other systems out there that function as crew-overboard alarm/alert systems but do not have kill-switch features. For the purposes of this Foundation Findings we limited our tests to those with an engine cut-off. Landfall Navigation has a good selection of crew-overboard devices currently available in the U.S.A. Companies around the world are introducing new products each year to help keep you and your crew safer.
There is no single device that is perfect for every situation. Each has advantages for specific boating conditions. A lanyard kill-switch is a must for anyone boating solo or operating a PWC, but it only provides protection if you’re wearing it. If the helmsman has to attend to something out of reach, it would have to be detached to avoid accidentally killing the engine. To prevent loss of power at a critical moment it should not be worn in an emergency situation or while docking.
