Found this on the 'Trawlers-and-Trawlering Digest', and I thought I would include it (with the authors permission, of course).

Subject: T&T: Boat Nanny
I have a slightly used (2 months) Boat Nanny that paid for itself in one call home.
This unit is great for boaters who are going to leave their boat at a marina for several weeks.
The unit works as a cell phone (a sim card is required) and calls or send email when a fault happens. It will send status reports once a day also:
The unit has motion detector, monitors A/C, temp & has a remote for any devise that has contact closure. A float switch is included if you want to monitor bilge level.
The unit is wireless and only needs to be plugged into a 110 volt outlet.
In my case the unit called saying shore power had been lost. I called the marina, but they said there was no power outage. I ask that they go look at the boat & they found that a boater had come in at night & unplugged my shore cable. When they plugged the power back in, the unit called and said all was OK.
If you have need of a Boat Nanny I have this one that I will sell for $675, new coat with the remote sensor id 1095.
If you would like to buy a new Boat Nanny, or any of the Marine Guard systems, drop me a line and we can discuss your needs.
