To free up room at the helm, move your VHF radio unit into the cabin and replace it with a remote full-function microphone. A number of VHFs have this option, including units that feature a "black-box" VHF. For example, with Icom's M400BB VHF ($499, icomamerica.com), the radio module is mounted out of sight. Its remote microphone includes all controls and a mini display. Garmin's VHF300 ($699, garmin.com) also has a black-box module that is placed out of the way, with all controls in a wired remote mic. You can also add up to two wireless walk-around microphones (GHS20, $399) for remote operation.
