Strength. ..or lack of is the disadvantage. This is somewhat over come by reinforcing the pipes with bamboo wedged inside and running the remaining cable I have at half height around.
Its not something I would trust my life at sea with. ..but its certainly better than nothing

Saw a cat recently and the French bloke had made his with stainless towel rails he procured from a resort being pulled down.
It looked really good
