The following are the best swimming strokes during a survival situation:
Dog paddle. This stroke is excellent when clothed or wearing a life jacket. Although slow in speed, it requires very little energy.
Breaststroke. Use this stroke to swim underwater, through oil or debris, or in rough seas. It is probably the best stroke for long-range swimming: it allows you to conserve your energy and maintain a reasonable speed.
Sidestroke. It is a good relief stroke because you use only one arm to maintain momentum and buoyancy.
Backstroke. This stroke is also an excellent relief stroke. It relieves the muscles that you use for other strokes. Use it if an underwater explosion is likely.
