Water Hazards (Rule 26) . . .
1. Play the ball as it lies. But do not ground your club in the hazard (Rule 13-4)
2. Replay the stroke from where you last hit the ball (stroke and distance)
3. Keeping the point where the ball last crossed the margin of the water hazard between you and the hole, drop the ball on the line with no limit as to how far back you go – penalty one stroke.
