We are in the process of finishing our install today, and, as discussed by Mark and others in this thread, are powering it with the AIS feed since VHF is not dependent upon the splitter being powered.
Regarding the mention about keeping AIS on for tracking in case someone borrows your boat without permission, we have two strategies:
First, we do leave AIS on when traveling on the boat and when anchoring
[but not in the marina...] with the appropriate status being broadcast by AIS. [e.g., Underway, At Anchor
Second, we cover remote
vessel monitoring [including anchor
watch, bilge pump
running, shore power
off, detection of movement onboard, boat traveling without permission, etc.] with a Siren Marine
vessel monitoring device that sends text messages you control [and works anywhere there is cell coverage world wide...]
However, it is dependent upon cell coverage. But it won't be obvious to someone joy riding our boat [a very low probability where we currently cruise
...] that this device is tattling on them, so we view it as a reasonable precaution- especially given the plethora of other features it brings to the table. [There is a brief article on our blog if you are interested in more details and why we installed a remote
Thank you for choosing to transmit as well as receive AIS- improving safety
