Dyneema topping lift failure

Indeed! I was thinking the same thing... I seldom leave the mainsail hoisted while I'm off the boat, and the battens are safely tucked into the boom bag.

To be honest, I don't have a topping lift... a rigid vang supports the boom, but perhaps you could forgive a little artistic license?

I don’t know about your boat, but my topping lift sings at 20kts. I try to foul it with the adjusting line, but it could still be vibrating.

Based on the fur, running 70-80% of the length, it is not chafe

Yup, I had a stupid moment. I won't defend that one!


I still wonder if the Dyneema has a different motion, and that it is rubbing on something in a specific spot. Otherwise, breaking in the middle doesn't add up.

Mine did NOT break in the middle. The entire run of the back stay had “fur” on it.

And yes, if you read my lost it does have a different motion- in vibrates in the wind and produces and audible hum at +/-20kts. Logically, it produces a sub-audible hum at other wind speeds. Dine fodder for a PS article😎
