I don't have a remote mic because frankly that would require about 11 feet of coil. I have a base unit that I monitor while motoring in the pilothouse (but rarely use to transmit), and a handheld I monitor while sailing and use to contact dock guys, sometimes the CG if I find picnic tables floating in the water, and other boats with whom I'm trying to rendezvous.
But mostly I just listen to other people or to the Wx. You can a great deal about human behaviour monitoring Ch. 16, I find.
