It also depends on the time of year you plan to go. Winter months usually have lots of wind and big seas. Summer months have tropical waves to watch out for. Just bring along some seasick medication for the Colorado natives. There are well protected anchorages on the south side of Grenada at Mt. Hartman Bay (Secret Harbour) and Hog Island. Neither one has swell, unlike True Blue or Prickly Bay. That is just in case you need a place to recover!
