Not exactly Olympic Diver form here. This looks like a 30ft jump into the ocean which can be pretty daunting for a novice swimmer. Believe it or not, the higher the jump, the harder the water gets.  At heights above 45ft, the risk of injury increases significantly. The right way to do this without injury would be to cross your legs and bring your arms across your chest and tense all your muscles tightly.  WESTERN PACIFIC OCEAN (Oct. 30, 2022) – A Sailor assigned to amphibious assault carrier USS Tripoli (LHA 7) jumps into the Pacific Ocean during a swim call Oct. 30, 2022. Tripoli is operating in the U.S. 7th Fleet area of operations to enhance interoperability with allies and partners and serve as a ready response force to defend peace and maintain stability in the Indo-Pacific region.

Believe it or not, Sailors in the US Navy spend most of their time on the water rather than in the water itself.  Even aboard subs, the sea is definitely kept out. Among the dozens of “ratings” or Naval Enlistment Classifications (NECs) in the fleet very few are considered wet ratings.  Navy Seals, Divers, SAR Swimmers, and coxswains operating small craft will spend plenty of time in the salty brine but for most Sailors, they stay high and dry.

The exception is an evolution referred to as a “Swim Call.” On long voyages, a couple of days are set aside for crew recreation aboard when there isn’t a port of call for liberty ashore.  The ship anchors in warmer, relatively shallow waters and the entire crew gets a few hours of recreation jumping into the water off the ship and a chance to swim.
