Welcome to Cruiser Log, Bob
I think that it would help to know a little more about you before our answers will be useful and neither patronizing nor too advanced.
Do you know how to sail? What kind of experience do you have? What kind of cruising do you think that you'd like to do - coastal cruising in North America, or cruising in the tropics as far as, say, the Caribbean? Or further afield than that.
Asking about a survival suit is interpreted by me to mean that your experience is possibly limited. I say that because I don't know more than two people who carried a survivor suit with them.
Anyway, please let us know what you think you don't yet know and we will try to fill in the blanks.
J
