Now, the Lifeline is on if the motor is on. Never mind mechanical failure or getting run over by someone else. I have proven to myself many times over in the past that I lack the discipline to only spank the Ally (or any other boat) when the jacket is on (planned runs).
I had a 90+ mph blowout while testing a new prop with the Lifeline and kill switch on some time ago. I stayed in the boat, but barely. My right hand had a death grip on the steering wheel while the Ole noggin hung over the left side of the boat (center steer). I only busted up some ribs that time while trying to not get wet. And the Lifeline added some padding which kept the situation (wounds) from being worse. As a side note, with the jacked up ribs, it would have been tough to swim if I would have been spit out and not have had the jacket on.
It should go without saying, the kill switch also needs to be hooked up. Imagine surviving hitting your boat with your body on the way out, then surviving hitting the water at a high rate of speed, only to look up and see your boat coming back to finish you off. Ain't the way I would like to go.
You guys have fun out there, but take care. It is much better to meet a fellow hi-perf boat owner than to read about one's demise.
