The only time we have been boarded was in the Grenadines - Canouan. On our friends’ yacht - a 48’ FP. They had an alarm and it went off when they tried to get into the salon. They installed alarms due to the repeated issues in the area (there were based in Carriacou). Only minor things in the cockpit area were therefore taken. Local police do nothing about it. The waters there anre beautiful but I never felt completely at ease. Our friends have since left the area (on a circumnavigation). They implied they would not return to base in that area).
