Rich, I think you were still with FM when this happened but down where the harbor tours leave from there's a floating dock attached to the fixed pier by a gangway. We ran a pipe along the gangway with that double swing joint (all flex couplings by the way) that I described earlier at both ends, and as far as I know there's been no problem. I have a concern that it might leak at a joint or two but no more than hose couplings so I doubt if it would be an unsurmountable problem.
