Railing added safety line

[HarlenW]

I want to add an additional safety line to the 1 1/4" stainless railing at the top back deck of my trawler. I envision two or three support poles of 12 to 18 inches with cable between them. It would be like what most sailboats have but I need to securely attach the poles to the existing railings. Does anyone know of any available products for this?

The aft upper deck area slopes somewhat at the sides and the installed railings would not stop one from going over if they fell against them.

Thanks.

You need to make sure how ever the bases are attach that they can with stand the additional leverage put on them when someone leans or falls against them.
