20 Seafari rigging tube/conduit?

[natecert]

I don't know about diameter, would think it depends on the height of the stringers and bilge. Regarding the bends/ radius, have looked at some you tube videos and hot sand or boiling water was used to get any bend you want.
As fredbrad said 90* pvc is a PIA even the 45* is not fun and agree with grey pvc. By all means include several extra pulls for the future needs.
