All kidding aside, if you do find yourself in this situation, 2 things are important, a high quality VHF antenna and the USCG, the radio is not so important because they all produce 25 watts of power. A DSC(digital selective calling) capaple radio is a plus also, these send an auto mated diistress signal with your boat name and position if you cnonnect a NMEA183 feed to it from your GPS, this signal can also be picked up by ships. All ship the transit oceans now are required to have a GMDSS (global maritime distress and safety system) suite onboard and these system will pick up your DSC distress signal. I have communicated succesfully with USCG from 20-50 miles out, not because your radio is super cool, but because thiers are. VHF is LOS (line of sight) the CG usually has very high antenna towers giving the greatly extended range. Boat to boat comms are not the good at any range because the combined ht. of the 2 antennas can be as little as 10 miles. Next time your out way offshore like that, call them up on 16 or 22A and get a radio check. They will not mind, they wold prefer you be safe so they don't have to start from scratch if they have to come find you. A float plan is also a critical thing when you fish offshore like that in a small boat.
