I don't believe so,, but the serious sailors use SSB, (single side band) which does.
You need either a ship's station license or a base station license for the radio. The radios need to be set up properly with oven controlled crystal oscillators to meet the frequency tolerances. +/- 50 Hz on the boat. +/- 10 Hz at the base station. The operator(s) need a 3rd class radiotelephone license. Basic rules/regs. I have a 1st Class grandfathered to a General Radiotelephone Operator's License (lifetime). In the late 70's I cared for the radios on 180 boats and about 14 base stations in San Diego. I moved on to PacBell when it was clear that the tuna fleet intended to leave town. That gutted the customer base.
