There are two types of boat diving: normal diving with the boat fixed with anchors and diving without fixing the boat.

The method of diving without fixing the boat is called drift diving, distinguished from normal boat diving.

Special attention must be paid to boat diving, as not only the feet are narrow on the boat, but also the feet become unstable due to the waves.

Sometimes you dive in places where the tide is fast, so listen carefully to the instructions of the boat staff and instructors, and stop selfish behavior.
