OK, I am not a sailor, so excuse my ignorance. Can anyone here answer some questions I have about sailboats, in particular Mr. Gray's sailboat? The following was listed as being on Mr. Grey's boat for electronics.

Electronics
EPRIB yes: Purchased at West Marine some years ago. It is small, self-deploying, self-activating, and not mounted outside. It is stored (not mounted) at the companionway stairs (in an open pocket). Brand and model are not known at this time. Is thought to be suitable for blue water use. It may not have been registered with the Coast Guard. The state of the batteries in the EPIRB is not known.
Radar yes: Raymarine SL-72 display, purchased in 2000.
Fathometer yes.
Knot Log (speedometer) yes.
GPS - yes (several): One is a Garmin 48, purchased in 2000.
Chartplotter yes: One of the GPSs has a chartplotter.
PC for Navigation yes, but it was left at home.
CD/stereo radio yes.
VHF radio yes: VHF is the fixed mount type powered by the boats 12 Volt system. The antenna location for this radio is on the masthead.
Handheld VHF yes: Standard Horizon HX-350s handheld VHF (submersible to 3 feet
for 30 minutes), purchased in 2000.
HF (single sideband) radio - probably not.
AIS Receiver no (for tracking large ships on a PC or chart plotter).
Electronic Autopilot yes: Autohelm that works off the boats house batteries.
Boat Batteries: Four 12 Volt batteries in two banks of two each. Normally used only one bank at a time. Controlled by a 1 2 Both type battery switch.
12 Volt charger for cell phone: Charge for cell phone and wireless device chargers may have been with him.
Cell phone antenna amplifier and external antenna no
OK---so what is a EPRIB? If he had radar onboard, couldn't they track him with his radar? It appears he has a radio--is there no way he could mayday or signal for help? I read that he has a cell phone but most likely could not get service out on the water.
