WiFi Installation on Your Boat


Captain Bob Damiano

Winter (and spring) (and summer) project: Argon gets WIFI


Since I live and work from the boat, good connectivity is pretty important.  We have a couple of 4G hotspots but those come with those annoying data plans. Our marina has free wifi (via Beacon) but all the cool kids put up wifi routers and have their own LANs on their boats.

So back in December, I decided to buy the stuff. I was going to buy a package from Island Time, but I thought I would be even cooler and buy the bits separately myself. That's a great idea if you're an IP/networking genius and can configure this stuff. So I got a Microtik Groove radio and router and started struggling with it (with lots of help from my boss, Dan who IS an IP/networking genius).

Ultimately, I ended up replacing the groove with a Ubiquity Bullet radio.  This thing is MUCH easier to configure and I was actually able to do it with some email support from boss Dan, brother Duane and brother Duane's friend Ralph.

So... I have a brand new Groove radio for sale if anyone wants it.


Physical Mounting

Argon has an Edson radar mast on her transom.  I spoke to someone at Edson and he suggested I buy this "wing" thing that mounts under the radar platform. This provides a nice surface to mount several small antennas.

To mount to that, I got a standard 1-14 antenna mounting base and an extension tube.

Wiring

The wireless router is installed inside the nav table instrument "pod".  I had to run a 12vdc line from a spare breaker to a new terminal block in there.  This feeds the router and the PoE (Power over Ethernet) injector to power the radio.

We also had to run Ethernet all the way from the nav pod to the base of the radar mast and ultimately up the mast to the radio.

About now, is when I got the network to actually work. Until then, it was a notwork.

Putting it all together

This involved finalizing the mounting of the radio/anenna to the mount, unwiring the radar mast and removing it from the boat, installing all the stuff and hooking it all back up.  And then really really hoping that everything still works.

We were smart enough to get help to re-install the stick.
 
And there she is.  DONE (finally)
