While John ( Ka4Wja) is very informed and a proponent of GMDSS ( as I am as a VHF
instructor and ham fan). I would suggest that given the OPs considerable setup, it doesnt seem necessary to add SSB
. Ive sailed several ocean crossinhs and considerable other mileage in many boats thats were never equipped with SSB
, in fact outside the "dedicated" blue water
cruiser, and leaving aside comms nuts like myself, there isnt a lot of SSB usage. In fact on Marine
SSB as opposed to ham Nets, theres hardly any traffic at all. And some nets are more like housewives talking....!!!
As for emergency
, I would still ascertain , that a satphone and a EPIRB
is a good belt and braces approach. Simply ring Halifax
or Falmouth directly from anywhere and leave them handle it. AGree what you said re rescue
times, but that applies to all forms of communications
. In my experience SSB comms to vessels is of limited use.
