Global Maritime Distress and Safety System (GMDSS)

Digital Selective Calling (DSC) is part of the Global Maritime Distress and Safety System (GMDSS), an internationally agreed-upon set of safety procedures, types of equipment, and communication protocols used to increase safety and make it easier to rescue distressed ships and aircraft.

DSC can be used to initiate ship-to-ship calls and distress signals. For the distress signal to work, the ship's Maritime Mobile Service Identity (MMSI) number must be programmed into the radio. A Maritime Mobile Service Identity (MMSI) is a series of nine digits which are sent in digital form over a radio frequency channel in order to uniquely identify a ship. Preferably, the radio is also connected to the GPS, so when the "Distress" button is pressed, the preformatted distress message will include information about the ship, as well as the position and time of the distress signal.

Non federal MMSIs are assigned by the Federal Communications Commision (FCC). For ships that do not intend to sail to foreign ports, the FCC has agreed to let BoatUS issue MMSIs. For boats that intend to travel to foreign ports, the MMSI number can be obtained through the FCC as part of the application for ships station license. A ship station license as well as an operator permit are required if you intend to sail to foreign ports and use your radio. A station license or operator permit are not required if you are sailing in international waters, only if you intend to visit foregn ports.

Kyocera KD135GX

These panels seem to be pretty common in the marine world. Since we took measurements of the bimini, and solar panel manufacturers give you exact measurements of their panels, I could superimpose the panels on the bimini and see how they would fit. These panels fit inside the backstays and block a portion of the windex window.

I even played around with the panels mounted sideways, but that just doesn't look right.

Solar Survey

We're thinking about adding solar panels above the bimini, so we took some measurements to see what sort of panels we can fit up there. The last time I was aloft, I took a picture of the boat from above, so I decided to create a little diagram with the measurements superimposed.A couple of tricky bits with mounting panels above the bimini. For one, we have double backstays that go through the bimini. Also, the bimini has a small window so see the windex on top of the mast.
We'll have to find some panels that fit inside the backstays, and don't interfere with the view of the windex too much.
