It is notable that without the ability to call for help or the ability to inform your family and friends that you were fine, you cause unnecessary grief, work and expense.
I was at a pre-race brief for the Van-Isle 360 a couple years ago and the organizers wanted everyone to carry EPIRBs and to check in on a comms schedule. Many argued with that saying they preferred to be independent. The Coast Guard pointed out that if they were overdue, the effort would be made to find them anyway. Having the proper comms/EPIRB just made the job easier or saved them from even looking at all.
While proper comms equipment may not trump the watermaker, it would be nice if people didn't start looking for you when you don't need help.
There is a tide in the affairs of men,
Which, taken at the flood, leads on to fortune;
Omitted, all the voyage of their life
Is bound in shallows and in miseries.
Shakespeare, Julius Caesar IV, iii, 217
