Part 12: VHF Install
So after the first initial sea trial, I went for another boat ride on a nicer day to test out some of the performance. It was later in the evening, and flat calm out, so I was only planning on running out to the CBBT. When I got there, I thought... well hey, it's so nice out that I could probably make it to the Chesapeake Light Tower! Wouldn't that be a fun ride! So I set out. Fast forward about a half hour, and another 15 miles offshore, and the "Bad Idea" alarm starts going off in my head. It's winter, the water is 40 degrees, it'll be dark here soon, nobody knows were you are... plus, I had no EPIRB, and no good way to call for help other than a handheld VHF with a dubiously charged battery in the emergency box. I pulled out my cell phone: 1 bar of service. I could see the tower a couple miles away, but I'm a fan of the old adage "just because you spent a lot of time making a bad choice, doesn't mean you should keep making it." I turned around and headed back in, and sure enough it was definitely dark by the time I got to the ramp. On the way in,
it was calm, but this was the Atlantic, and there were a couple times that I launched the boat at 30kts off a big swell, and didn't particularly like feeling as though I could go overboard and get to watch the boat motor away with nobody on board. For the first time in awhile, I put on the corded kill switch, which made me feel better but was a true pain in the a$$ to work around.
This little unwise venture made me realize a few things: I don't like not having a solid means of communication; and I also need a better way of ensuring I stay with the boat should something happen.
In order to solve the first issue, I decided a fixed mount VHF was in order. I have an Unlimited TowBoat US membership, but that doesn't do me much good if I can't call them. And, as my almost entirely discharged (as it turned out) handheld VHF proves, I don't want to have to rely on just that one unit. Some pictures of the install are below:

I went with an ICOM M330G unit. It's one of the most compact fixed mount VHFs I could find, while still having all the features I wanted. It has an internal GPS receiver, so the DSC distress feature will work without needing to be connected to the network.
For the antenna, I installed a Shakespeare QuickConnect rail mount with the 4' fiberglass antenna. The QuickConnect antenna allows me to remove the antenna completely from the rail mount for storage, or if using the console cover. The cover fits with the antenna in the down position, but just barely. I ran the coax cable through a Scanstrut cable gland on the side of the console, to a Shakespeare antenna splitter in anticipation of adding a stereo at some point. The coax from the splitter and the power wires then go through another cable gland on top of the dash to the head unit.
The head unit comes with it's own GPS puck antenna for the internal receiver. Which is great, except that it has a 15' cable attached to it. I needed about 6"; and I wasn't a fan of having all that cable bundled up on my dash:

Instead, a quick web search led me to a stubby, right angle GPS antenna with the same SMA-male connector. $20 and a few days later, and I have a perfectly functioning VHF with GPS input, and a much cleaner installation:

So at least I now have communications, and a way to monitor weather alerts while fishing the bay.
