Yes Bill, welcome to the forum! As I am sure you are aware, when heading south from St. Lucia it is best to avoid the west coast
of St. Vincent and, while thefts are up in Bequia, Admiralty Bay is still reasonably safe (although it a good idea to get to know some neighbouring boats and set up a boat watch). The rest of the Grenadines are pretty safe, as is Grenada
. In terms of Isla Margarita, a very cheap
place to get supplies (the island is duty free) and there are some large supermarkets within cab distance of the harbour in Porlamar. Again, set up a 'neighbourhood watch', lift
up and chain your dinghy
at night, don't wear expensive jewelry/watches and take some care at night in Porlamar (it is a relatively large city with all the problems that entails).
