In a distance race, the sailing instructions indicate an area that is to be considered an obstruction and boats in the race are prohibited from entering that area. Boat A believes Boat B passed through that area. The race continues for several hours after passing the prohibited area. Boat A is not within hailing distance of Boat B at the time Boat B allegedly entered the prohibited area nor at any time subsequent in the race. Boat A does not raise a red flag nor try to hail Boat B in any fashion, including on the radio. Subsequent to finishing, Boat A informs Boat B of the protest at the first reasonable opportunity.
Did Boat A comply with RRS 61.1(a)?
