Scuba divers don’t always dive in backward with the back roll entry, however. You may see divers taking using the “giant stride” method on larger boats and yachts specially outfitted for scuba diving, which have stable dive platforms. “Keep a hand on your regulator and mask as you prepare for a giant stride,” A-1 Scuba & Travel advises. “Check the water for any obstacles before stepping out into the water and be sure your step is large enough to avoid hitting the side of the boat with your tank.”

Then there’s the “seated entry” method, which is involves sitting on the gunwale. “Put your legs over the side and hold on to the side of the boat with your arms,” says A-1. “Turn around, so you’re facing the boat as you lift yourself over the edge.”

Happy diving, folks!
