After working on the waterfront for many years, I still shake my head in wonder for the number of times I have seen a seemingly unsolvable engine starting problem traced back to a pulled kill-switch. It has humbled the best of us at one time in our maritime careers. Regardless of what trouble a kill-switch can cause, they serve an important boating safety function that we should always consider. A recent study by the BoatU.S. Foundation highlights the importance and operation of these safety devices. A complete report titled Keeping Current on Kill-Switches in Portable Document Format is available from the foundation. Interestingly, it’s not a kind of industrial stitching fremantle job in marine world. It has different perspective and it comes with different solutions at the same time.
