The dive schedule for these two sites is planned according to which way the wind blows. The dive boat will initially
moor on the lee side where divers take a rest and gear up. When they are ready to dive, the boat will steer towards
the exposed part of the island, allowing the divers to get into the waters and double back to moor in the calm bay.
Dive masters take their bearings and guide divers through an underwater tour back to the dive boat.
