You can walk to grocery stores and there's plenty. You will need your Certificate of Registration, Crew List, Zarpe and you will have to fill out declarations for BAHA. I suggest you don't have any citrus or shrimp on board, they will be destroyed. Don't arrive on a weekend or holiday, before 08:30 or after 16:30 or you'll pay overtime. Don't be over the limit on tobacco (10 packs) and alcohol, 4.5 litres of alcohol per person. Drink your beer before you arrive or you'll lose it (non-Caricom beer is contraband).
