It is recommended that in areas where a marine radio is required, a VHF radio is a better choice than a 27MHz radio. The 27MHz is the cheaper option but is inferior to a VHF.
For coastal operations a VHF radio provides much greater coverage and allows communication with shore stations for distress and emergency situations. It also allows boaters to talk with commercial vessels if necessary.
The MAST VHF repeater network gives statewide coverage and allows vessels in distress to communicate with each other. Traffic on the repeaters is monitored by volunteer groups.
More detailed information on VHF Radio is available in the Marine Radio section of the MAST website.
