Nice piece of new equipment for my boat

So I was trolling around at West Marine the other night. I am wanting to add a house VHF radio to my boat. I really wanted to put one with an AIS receiver in my boat but the $400 or better is steep.

And then I saw it! Standard Horizon DX2150 for $200. It has DSC and AIS receiver. Normally $400 but close out for $200.

I immediately went to my local West Marine and spoke with the manager. They didn't have any in stock or any in the warehouse. He called around and found me a display unit and I said "I'll take it!"

Now I have a big project ahead of me for this winter. I am going to install this VHF with AIS into my Compac 23. This means that I have to run coax inside of the mast (with the zip ties with tails to prevent it from slapping inside of the mast), run coax through the deck, mount a masthead antenna, and mount the radio. The radio will then be networked through NMEA 0183 network to my Garmin 441s.

Here is the beauty of this. The VHF will report the AIS positions of any ships in the area and they will show up on my GPS. I will know their speed and heading AND get an alarm if they get in a certain proximity of me, that I set. My VHF will automatically send my GPS position to the coast guard if the MOB or the Distress button is pushed on the house radio.

While I am running to coax cable I figure that I might as well re-run the anchor light wire and put zip ties on that as well because it slaps sometimes.

This is a medium to big project but I am excited to have this aboard. This is a pretty nice and serious set-up. I think that it will be a good safety feature too. It isn't quite as good as radar but it is much cheaper.

That was a good deal. I got a nice price on a B&G AIS/VHF this year as well and have been enjoying getting used to it too. If you don't mind sacrificing some range temporarily, you can mount the VHF antenna on the rear railing and save the big job for later. I've now discovered that in this area there are lots of fixed AIS transmitters (ATONs) on the bridges and bouys that show up as well. Also there are "Virtual" AIS targets that show up too. The Coast Guard transmits a signal that appears to come from a specific location (where nothing exists) to warn of particular hazards or other reason to inform mariners for safe passage. I've never had radar but think this is a really useful alternative, especially with the ability to directly contact ships if necessary.

My Garmin 478 is a bit too old to accept the AIS data (and display it) so I am currently using a laptop with OpenCPN software to display the ship data. Looks like a new GPS plotter is in the future.

Boat is already out of the water for the season so it won't be a big job to run the wires. I am kind of looking forward to tackling this project.

Am I the only one who feels accomplished when they complete a boat project like this? It is cool to learn new things and the more you know about your boat the better!

Installed a new VHF with AIS this spring before a trip to Florida and back. Had to turn off the alarms - they were driving me bonkers!! You have no idea how many vessels are transmitting AIS info between Galveston and New Orleans. Hundreds and hundreds. Busiest part of the ICW , tip of Texas to Norfolk, bar none.

But I liked having the vessel names as I passed them

I forgot about the alarms. I had to disable mine too. The four stanchions on Oakland Bay Bridge are always on a collision course with us.

One thing I like is that even before leaving the dock, with AIS I can see out into the main bay with what is going on with the vessel traffic. There are too many obstructions for radar to work that far away unless I had a 100 foot mast.
