Rich...ah, a favorite H/PC Guru you are!
If you have 120v A.C. power at the slip, or 12volt battery power, consider taking any home router with dual frequency 2.4 and 5 GHz WiFi down there and connect Ethernet cable from camera to the home router and a laptop via Ethernet or WiFi to it.
This will allow you to then configure your 5GHz camera to use the open 5GHz SSID
(using your laptop
), since if I understand what you're saying the Ethernet connection is only needed for initial setup, right?? Once set up... take your home router back to the neighborhood widows..., er... home.
This assumes your camera can use the standard http port 80 or https 443,
( no special 1026, 3389, etc... ports as the Marina router most likely has all other ports closed
). Also assumes camera accepts open wifi...
The WiFi extender mentioned above is a good alternate option if you need 24/7 WiFi subnet "bridged " to the marina wifi and they're cheap like $15. You can then set wifi security on the extender subnet, too.
I have an Iogear ethernet2Wifi adapter... its only 2.4 Ghz and runs a bit warm on 5volt sub micro power and is transparent ... cost about $40 but should work if only needed for set-up.
So... depends on what you need and "how long "
( NOT talking about widows or cicadas here...
).

Addendum: I used the low temp bismuth solder for Jornada battery rebuild... thanks for the good tip on that!
