British yoga instructor mutilated by prop - Cozumel

Instead of prop guards which reduces efficiency, can’t there be a funnel like device fitted so behind is just a jet stream while in front is well under or in middle of boat

A propelsor, or a jet type, will be more dangerous. As they can suck things up.

A gently spinning prop, is more of a paddle wheel or a screw. Sure, it'll suck at full throttle, but not so much at idle IME.


Every dive boat I've been on, was direct or v drive, prop under boat. Never stern drive.

It sucks only from under or middle of boat which is much safer won’t it

I was almost axed by propellor blades in Thailand. The captain had us gather on the back deck of the dive boat as he maneuvered into place. He sounded the ship's horn as the signal for us to jump in the water.

On this particular day, halfway through the dive cruise, I was standing on the very edge of the back deck and I was the first person to jump in after the captain sounded the horn. But apparently the captain changed his mind after sounding the horn, and he decided to back the boat into another position. The dive guides saw the signal from the captain, and they grabbed all of the other divers to prevent them from entering the water. The captain gunned the engines into reverse after I had already jumped.

Next thing I saw were two big propellor blades coming at me. I barely escaped with my life.

I WAS PISSED OFF, and the boat crew blamed me for jumping into the water when the captain sounded the horn.

My instructor recommended jumping in with a wing half full. Kinda negative entry, to mitigate that.

But a dive boat should be in forward gear the whole time. Pointed away from shore. That's insane. The amount of crazy stupidity from boat ops and tank monkeys is amazing.

The best vacation DSMB, is another diver. Lol.

Sorry to hear this but glad to hear you are ok

My boat unfortunately has the divers very close to the wheels when they are boarding. For this reason, I always have my engines off, not in neutral and able to be bumped into gear when loading and unloading. (since I have an engine kill tether and the lift controls are in the back, it isn't even optional.)
Obviously, I could still run over somebody when not loading but I do what I can to mitigate what I can.
Not sure if this video will load, but you can see my wheels in relation to the lift platform.

A wheelchair lift? That's too cool.

A wheelchair lift? That's too cool.

If you had a 28" airplane wheelchair, I suppose it could be.

Looks bigger in the video.

Would a prop guard be realistic to help keep body parts off the blades? Or too much resistance and maintenance?
