Vibration due to a damaged prop is caused by the mass of the blades being grossly out of balance. If you had a prop that was badly chewed or bent on all 3 / 4 blades then it wouldn't vibrate very much at all. However if you've only bent one blade (even if it hasn't actually lost any material), the radius about which the mass rotates will have changed causing huge vibration with seemingly little damage.

Yes, with one blade missing the vibration was huge and I feared for the engine.

So I switched off and drifted home on the tide steering with an oar.

A new prop the next day (they can't fix damage that bad) everything was fine.

Sixy,

Sounds like you got it right. What you say seems to tally with what happened to me.

Tim,

I had a considerable distance to get back. So I'm fearing the worst with regards any bearings on the prop shaft. I have noticed a little bit of movement of the prop and shaft so I'll have to wait and see if this is within tolerances. I seem to remember it had a little bit of movement before but I'm not 100 % sure on my recollections. I noticed the movement when I changed the prop earlier this year and although I thought it strange at the time I had no reason to believe I had a problem. Next week will tell.

Cheers,

Yes the insurance should cover any big bills. Now my big bug bear is getting it all sorted so I can get back on the water soon.

Good luck with getting it all sorted out.

By the way, I did get back in time to do the school run!

It was very rolly in Freshwater Bay so we just blasted back to the Island Sailing Club for a pint and a sandwich.

Hope to see you out again soon.

I thought it might be so. No protection from the way that wind was blowing. I would like to land in Freshwater Bay one day that Hotel looks nice.
