The predictor line extends from yourcurrent location toward the start line and the laylines that extendfrom each pin.The end point and color of the predictor line indicate where theboat will be when the timer expires, based on your current boatspeed.When the end point is before the start line, the line is white. Thisindicates the boat must increase speed to reach the start line ontime.When the end point is past the start line, the line is red. Thisindicates the boat must reduce speed to avoid a penalty forreaching the start line before the timer expires.When the end point is on the start line, the line is white.
