Question 1

Shortly after the start Yellow and Blue are close-hauled on port tack. The boats are overlapped and Yellow is keeping clear to windward. As the boats pass to leeward of mark L, an inflatable buoy that is not a mark on this leg, Blue luffs and Yellow responds. Yellow stops luffing when she hits the mark amidships, which causes Blue to curtail her luff. Both boats display flag Y. What should the call be?

Answer 1

Question 2

Would the answer be the same if the boats were passing to leeward of an object that was not big enough to rank as an obstruction, but nevertheless limited her ability to respond and/or could cause damage to the hull or foils?

Answer 2
