If above water we would have fire exposure concerns, I doubt UV is an big deal. I am not sure if the multiple flex. couple recently suggested would provide enough flexibility for tidal issues.

With the braided rubber hose I'd be concerned with degradation due to temperature (range is 0F to 120F) and the fact that it will be dry most of the time. Not sure about any issues with UV with the S.S. braided hoses.

We have approved high pressure steel braided rubber hose for these situations often, as long as they installation is such that the hose remain submerged. Not a whole lot of better options that we are aware of at this point.
