Some people mistakenly call this an undertow, but there is no undercurrent, just an offshore current. If you are caught in a rip current, don't fight it by trying to swim directly to shore. Instead, swim parallel to shore until you feel the current relax, then swim to shore. Most rip currents are narrow and a short swim parallel to shore will bring you to safety. Alcohol is a major factor in drowning.
Alcohol can reduce body temperature and impair swimming ability.
Perhaps more importantly, both alcohol and drugs impair good judgement, which may cause people to take risks they would not otherwise take. Surfboards and bodyboards should be used only with a leash. Leashes are usually attached to the board and the ankle or wrist. They are available in most shops where surfboards and bodyboards are sold or rented. With a leash, the user will not become separated from the floatation device.
