Sea Legs
The acquired ability to balance, move and work comfortably on a vessel in motion.
Developing sea legs involves adapting posture, timing and movement to roll, pitch and acceleration and is separate from complete immunity to seasickness. Adaptation varies between people, vessels and conditions and can be lost after time ashore.
Experience does not remove fall or injury risk. Handholds, secure footwear, deliberate movement, safe routes and personal attachment where appropriate remain necessary, especially when fatigue, darkness, cold or sudden motion reduce coordination.
