Polysteel rope for mooring strops?

[Chiliblue]

Title says it all really.

Looking at breaking load/diameter it looks ideal for the job... am I missing something?

A lot of Scottish commercial yacht moorings are using it for risers instead of chain nowadays, it is almost universal for anchoring fish farms and the same workboats often set up yacht moorings, the moorings with strops made with it tend to be for fishing or workboats but if you look at the mooring anchor section on Gaelforces website you will see that they advocate a mixture with chain on the ground below the polysteel riser. The only issue with strops would tend to be abrasion but it is probable as resistant as any other kind of rope.

My only concern would be not being able to see any corrosion that may lie beneath. **This is why it is generally not used for lifting gear.

What corrosion?-polysteel either twisted or multiplait is all plastic-I use one inch multiplait as my riser and one inch twisted as strop after swivel.

I just replaced my 20mm nylon three strand with 8mm off cuts dyneema.
Then realised, too late, that the dyneema is going to cut into the protective tubing with time.
I also don't have a bow roller as such and there are some small gaps in the SS where the dyneema runs / cuts.
So going back to 20mm three strand

OK... why twisted for the strop?

I was going to run tubes over all chafe prone areas...

Perhaps you are confusing Polysteel with Combination. There is nothing to corrode in the former whereas there is in the latter.
The more appropriate reason for Polysteel not being generally used for lifting gear is that there are much more suitable materials such as chain, wire and in recent years, dyneema.

Appologies, my mistake. I was thinking of the nylon coated steel slings I have seen used occassionally as berthing strops.

Been using 4 strand polysteel strops (over bow rollers) for 3 years now, still in better condition than nylon would have been, I used to have to change those after around 18 months..
