Hi Dan,

I use those ropes for all my 4 rotating towers of 3x45m and 1x35m.

Check LIROS-Regatta 2000 from:

http://www.liros.de/artikelliste.aspx

Yachting->Watersports->Performance

It is Dyneema SK75 with plaited polyester cover. With the cover UV is no
problem of course.

I am very happy with them. They do stretch a little over time and I have
maybe had to tighten them once or twice over 3-4 years or so.

They are very strong, I use diameters from 5-10mm for towers. I use
3-4-5mm for many other guying and pulling purposes at my station.

I used the 2mm diameter rope (240kg breaking load) to pull out a car stuck
in the mud as experiment and it held up. The guy whose car was totally
stuck in deep mud looked at me like I was a complete moron when I hook up
this tiny rope instead of normal towing rope:)

Hello

Could someone share information about a personal experience the using for
tower guying Dyneema SK75 (or similar) ropes? I am interested about ropes
resistance to UV and what is durabillity of these ropes...
I know it is popular Philystran ropes in USA, which are made from Kevlar
(aramid fibres), not from SPECTRA /DYNEEMA (high tenacity polyethylene)...
But anybody has used spectra/dynemaa ?I heard some rumours, that
spectra/dyneema afraid of UV, but manufacturer declares "good UV radiation
resistance" ...

Thanks

Dan
