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.
