Next all of us who cruise can do the same..
charts and chartplotters are not that hard.. anyone with a gps can plot coordinates. Under International Maritime law, I am bound to respond to a distress signal. One has to wonder how many dives can say "MAYDAY, MAYDAY, MAYDAY"... rule is thrice... it gets attention.. if someone gets on a vhf on channel 16 and starts chattering about being left behind or hurt.. I may or may not listen.. but IF I hear those three words.. you bet your bippy I will perk up and pay close attention. Rules also say I have to have my radio on the second I leave the dock. If I hear "diver at xx lat and yy long" I can literally have it entered into the
chartplotter in a few minutes and have my course plotted as can anyone with
charts and a plotter onboard.. I don't know a
serious boater/cruiser to does not have this capability.
finaly pretty much ALL Cruisers nowdays have a SSB HF radio onboard as well as the VHF. As someone has already said.. VHF is line of site and the curvature of the earth plays into that as well as how much power the unit it pushing and how high the antenna is.. on Magnolia the antenna and wifi is 45 feet up... that is my mast ht or air draft if you will. I have, sitting here in the marina, heard the dockmaster at the Heminyway Marina in Havana talking to incoming boats.. other nights I am lucky to get the 1.5 miles to the BOATUS boat at the citymarina. I was DXing with a friend early this week and we went offshore and pushed some serious wattage (we were 5 miles out in international water) and picked up Cartagena
Of course that was NOT with a SSB... we would never have a modified radio onboard that has all the ham bands AND SSB... not me... never..
