Life line mystery

I am totally befuddled by this. I had a snow issue on my winter cover several weeks ago where the snow load pushed the winter cover over to one side. I had ABS "ribs" attached to the stanchions with 2 plastic cable ties on each side as the supporting structure. It wasn't pretty, but not a huge issue either,so I removed the snow (which really wasn't a lot) and took the tarp of given that it was end of snow season (so I thought) anyway. When I was leaving the boat, I noticed that the port lifelines were very very saggy by at least a couple of inches. The starboard side was normal.

I was afraid I had bent a stanchion or something but could not find any damage whatsoever and each stanchion was at the same angle and profile as its corresponding stanchion on the other side.

last weekend, I went back to the boat to do some more work and noticed the port lifelines were totally back to a normal tension. Either I was dreaming or some wierd warpage happened that self corrected.

Any possible explanations? EVerything looks very normal on the boat now!

I am not really from Toronto

Re: Life line mystery

That is rather odd! The only thing I can think of is perhaps the pulpit got distorted by the load on it, and after the load was raken off it took time to spring back to it's natural position. I is a bit of a stretch because you would think it would bend, and stay bent. Either way, depending on the design the pulpit conection point can have a big influence on lifeline tension since they often flare out at that point.

Steel is springy, so it would return to it's original state right away. My only guess would be deflection in fiberglass somewhere which took a lot longer to return to it's natural state. Maybe check for delamination and moisture around all of the stanchion and pulpit bases?

Re: Life line mystery

With the one 36 inch storm in 14 hours we had this season I was not able to shake the cover near as fast as it built up

Everything did recover BUT it had a heck of a load on it for a few hours

If a dirty bottom slows you down what do you think it does to your boat

Re: Life line mystery

Did you clip the lifeline gate the same way both times?
