Water temperature can drop to 6 degrees Celsius in the colder months, so a drysuit or a thick wetsuit with gloves and hood is worth packing even if conditions look mild topside. Air fills and a dive shop are available, but confirm your gas plan and deco schedule before splashing, as the 27-metre depth leaves little margin for improvisation.
This dive trip leaves the Point Pleasant Beach dock at 6:00am. Please arrive at the dock at least 1 hour prior to departure.
