I set up Nano Stations for Long Distance reaches, often needed by mariners to access web.
Using M2 Nanstation by Ubiquiti, adding anAirGateway the M2 communicates with distant wifi source, AirGateway creates a local wifi network in vessel.
The AirGateways are cheap enough at <$50 and M2s vary in price new/used.

If this is something that interests you my fee to set up M2 and AG is $50 once we have the hardware in hand.

Also available Marine charting GPS install for laptops or PC's. Charts and install $75, you'll need a nMEA GPS as well. Varying prices online, inexpensive.
