We have spent 4 seasons in the Carib, Bahamas
down to Grenada
. We intend to return in March/April.
As to currents your question covers a gery broad geographical area. There area areas with substantial currents but none I would consider “unsafe” because of currents.
As to cruising as a single
female hou probably have some greater risk than as a single
male or couple. In my experience the risks are about what you would expect in any large metro area. **** happens but most time if you have good situational aqarness yiu can mitigate successfully. So far I have had only one night where Istayed in the cockpit
due to concerns, and that was onlyfor an hour or 2.
The waters off Hondouras are another matter and should be avoided. This is a well documented problem area.
