In a multi-fleet dinghy regatta, the SIs state that “after the first warning of the day the Start/Finish lines are restricted unless preparing to start, starting or finishing.” No mention is made of any areas designated as obstructions.
The courses are Windward/Leewards with the Start/Finish line in the middle of the course. The leeward mark is placed such that the boats sailing from the windward mark to the leeward mark must alter their proper courses to avoid crossing the line.
After the start of one or more of the fleets, while boats are approaching the line from the windward mark, the Race Committee shortens the line by moving the starting pin closer to the Committee Boat.
Boat A rounds the original line. Boat B sails around the new, shorter line. Sometime later, Boat B passes Boat A.
Is Boat A entitled to redress?
