Best wifi setup for a boat

I have a sailboat and I want to be able to do 2 things:
!. Boost the wifi signal at the marina that is currently too weak to do much of anything,
2. Be able to 'tap into' free wifi when I am anchored on the water, with perhaps a 3+ mile range.

I've been considering an externally-mounted 8dB gain antenna with an inline wifi radio "bullet" connected via POE (no coax loss) down to a 12V power supply. My question is: what device should I plug the ethernet cable into (wireless router? WAP?) and what type of ethernet cable should I use?

I will want to connect at least 3 devices to the router/WAP, including a tablet and a cell phone via wifi. The router/WAP will have to run off 12V batteries and it should draw minimal current. The boat is 38' long so the "local" wifi signal does not have to reach far but it needs to allow for fast connections, as I will be using this link for business and that includes occasional video streaming and web sharing (i.e. Skype, Webex, GoToMeeting).
 
Solution
a possible (Rube Goldstienien) solution would be

wavewifi antenea to Amped Wireless AV3000.

If the local Harbor WiFi requires nothing more than a passphrase and give IP address' this might work.

I use the AV3000 to bridge wifi from one end of a home to the other then it both drops Ethernet and creates a local wifi.

Thanks, corroded. I am aware of devices like the bullet and the rogue, which are in-line wifi radios that connect directly to an externally mounted antenna. My question is more along the lines of "OK, then what?" It seems some of the "marine" routers and WAPs run in the hundreds of dollars, when a simple off-the-shelf router might do. 2 questions:

1. Is a router the right solution, and if so what attributes should I be looking for so that it both extends the wifi from shore and creates my own onboard wifi network?
2. Are off-the-shelf routers capable of running on 12VDC?

If I was to go with one of the "marine" solutions it would cost $500-600. I believe I can replicate the solution with off-the-shelf components for about 1/3 that cost. Maybe I'm wrong but I suspect not.
