Drift Dives Experienced divers are always looking for new challenges to develop their diving skills. Sometimes it is deep wrecks, sometimes caves, and sometimes it is drift diving. Drift dives where you have no hope of swimming against the current. Drift dives where the current flings you along and the seabed passes in a blur of marine life. Drift dives where you can spread your arms and play at ground attack aeroplanes strafing the lobsters and crabs.
Drift dives of the brown underpants variety.
There are a few general considerations of seamanship and diving that are pretty much universal where strong currents are to be found. Sudden changes in depth can lead to vertical turbulence in the water, particularly where the seabed suddenly drops over a wall. Even the most experienced diver will not be able to control their buoyancy in these conditions. A high speed drift needs to be planned to avoid such overfalls, by either diving on the tide that takes you away from such descending walls or with a precisely calculated and strictly adhered to time limit that brings divers to the surface before they drift through them. Local skippers will have seen the stretch of water you are drifting at all states of the tide and weather conditions.
