I was puzzled by 18.2b, wondering if the word gybe in place of tack could also apply when boats approach the leeward mark on opposite tacks. Evidently not, as shown in example 3 and 4. The mark room obligation doesn't turn off until boats turn head to wind, which doesn't happen on the down wind run, regardless of whether either boat gybes. Thanks for also including the examples showing when 18.2a applies.

Thanks for the comment!. 18.2 b doesn't address tacking or gybing. At the leeward mark, the obligation to give room doesn't change if one of the boats gybes. However, the obligation to give room at the windward mark does change if a boat tacks in the zone. This is covered by Rule 18.3.

The rule 18.2b consists of two conditions, the first says "overlapped when the first of them reaches the zone" and the second "If *a boat* is clear ahead when she reaches the zone" without specifying first or not - I would have thought that particular difference is intentional, why else would it be? I couldn't find any elaboration on that

I found the Case 59 at your website, it addresses the case when boats only become overlapped when second reaches the zone, i.e. 18.2b doesn't apply indeed. It still would apply if the second boat reach the zone clear ahead

I have a question regarding 18.2 C2 When I am rounding a mark and have mark room, it is said in 18.2C2 that (2) if she becomes overlapped inside the boat entitled to mark-room, she shall also give that boat room to sail her proper course while they remain overlapped. It is clear for me that, I with mark room, have the right to sail my proper course to "shut the door" for the other boat to round the mark. That is force the other boat on the wrong side of the mark, sail to leeward of me, or protest if I can't sail my proper course rounding the mark because the other boat is in the way. I don't know what right I have to sail above my proper course to "shut the door" on the other boat trying to round the mark on the inside of me? One example might be that I am late taking down my spinnaker and slide down leeward from the mark trying rounding it. I notice that there is an other boat now trying to round the mark inside of me, so I want to "shut the door" and force him to sail on the wrong side of the mark, or to leeward of me, or just make him brake rule 18 by not giving me room to round the mark. I do this by sailing "above" my proper course "head to wind" to close the gap to the mark, so that the other boat is either forced on the wrong side of the mark, sail to leeward to me, or give me the right to protest because the other boat is not giving me mark room to round the mark the way I see fit (this time above proper course). What are my rights and the other boats obligations if I am sailing above proper course (ie not sailing proper course stated in 18.2 Cs) and the other boat: 1, is forced on the wrong side of the mark. No contact and the other boat can avoid med in acting in a seamanlike way 2, Is forced to sail to leeward of me. No contact and the other boat can avoid med in acting in a seamanlike way 3, Is forced on the wrong side of the mark, this time as a panic action to avoid contact with me. (non seamanlike action to avoid me) 4, Is forced to sail to leeward of me, this time as a panic action to avoid contact with me. (non seamanlike action to avoid me) 5, The other boat is forced to hit the mark to try and avoid me. 6, I need to avoid contact by keeping clear of the other boat by bearing away while sailing above proper course. 7, We have contact, but no damage. Long question that boils down to what rights I have as a boat with mark room to sail "above" proper course trying to hinder the other boat to round the mark. Sailing my proper course I will be exonerated breaking rule 15, 16, 31 according to rule 43.1b and rule 14 according to rule 43.1c. Do I have the same "protection" by being exonerated by rule 43.1b and c if I sail above my proper course, ie not sailing my proper course. May a boat with mark room sail as "she wish" and still be exonerated by rule 43.1b and c? What restrictions are there on me with mark room?

Your proper course is the course you would sail to get around the course the fastest in the absence of other boats. If you can round close to the mark by luffing after slipping to leeward, this is likely your proper course. Therefore you can shut the door on the other boat.

@@SailZing Thank you for your answer! When sailing proper course it is more straight forward, as you write. I am curious about when a boat with mark room sails above proper course, for example head to wind, to "shut the door". See question 1-7 above. I have looked in many places, but can't find the answer. I had a young sailor asking me that question at a seminar I gave, but can't find an answer.
