No problem. I am trying how to figure out how best to stay safe. The radio came first to mind. That lead to other concerns about how they'd find me, etc.

I did a little fast swimming after the boat this last summer and I thought if this happens when I am on one of my distance sails, and I can't catch the boat, I could bob around for quite some time.

Didn't you also look at a teather of some sort?
