Provide in advance information about what passengers could expect on a trip. What conditions they might encounter, the hazards and level of strength or capability it might require. Don’t assume they would appreciate these things, even if they knew a bar crossing was involved or had crossed a bar previously.Operators should ask about passengers’ age, health/mobility status and prior experience, and exclude people not equipped to handle a trip because of these factors.A safety briefing prior to a bar crossing should include telling and showing passengers how to brace with their legs when the boat encounters a wave. It should be clear the passengers have understood.
