Canopy SU in Marina environment

Looking for an experience installing Canopy SU’s in a marine environment. Have customers on live-aboard sailboats in a marina. SU’s would be located on a piling next to the boat. Woried about long-term affects of exposure of the SU to the environment, are any weatherization steps in order here, and if so, what?

we are using them fine in our 200 slip marina. we are also using 802.11 tranzeo ap’s for those people who bring their laptops already configured with a wireless card
