Hi,

Thanks for all your suggestions.

As Dacron and Kevlar ropes are not available here, i think i have an 
alternative non conductive strong material close of my town.

Somebody know the SLING used to move products at the harbor ???...from and 
to the ship.

I think i can get that SLING from the harbor...i know it is very strong but 
i dont know if this material can survive the weather here...UV radiation and 
marine environment.

73....Douglas, CO8DM
