Oppostie Gybes, leeward Mark

( my point being that the definition of mark room includes the bit about no farther: this means going no further PAST the mark than you need to. If gybing, once AT the mark you can't sail further, and of course you can't leave the three boat zone to gybe.)

In the diagram:

- initially Green was clear ahead and Red was required to keep clear. Green could sail any course (subject to the limitations of rule 16)
- when Green gybes on to port the becomes the keep clear boat, but is entitled to mark room.
- Green does not sail directly to the mark and if Red was obliged to take action to avoid Green then Green broke rule 10 and should take a penalty.
- when Green gybes back, if she is still clear ahead Red must keep clear; If Green is overlapped to windward she is entitled to mark room to sail to the mark.

Originally posted by JimC Well, no doubts under 18.2 that green is entitled to Mark room... So we go to the definition... Mark-Room Room for a boat to sail to the mark, and then room to sail her proper course while at the mark. However, mark-room does not include room to tack unless the boat is overlapped to windward and on the inside of the boat required to give mark-room. All the way through green is entitled to mark room by that definition. Whilst green was clear ahead she was right of way boat: R12 I reckon when green gybed onto port an overlap was created, and she ceased to become right of way boat and was required to keep clear of red (R16) but red wasn't required to give green room, (R15) since it was green's actions that gave red ROW. So once the boats were on opposite gybes red was ROW, and thus green was only entitled to room to sail to the mark. She's not yet at the mark - indeed sailing away from it - so I reckon proper course doesn't apply. Thus until red gybes I think green is sailing higher than entitled to. Once red gybes green becomes ROW again. What it would come down to, I suspect was whether the PC found that red could have given green mark room without gybing if green hadn't sailed so high when they were not ROW, but I'm no rules guru.

This is almost the situation I meant: But if green was on STB and red was on port, green overlapped b4 the 3 zone, then can green "sail" by filling her Assymetric and not drifting to the mark in  light winds?

Ie sail the kind of angles in the diagram, just initially ongreen boat STB-Port red ?

Originally posted by ColPrice2002 "To" has no special definition, so it's from the "mark room circle" to the mark. It's difficult to interpret as "sailing high then gybing" because it doesn't refer to "proper course".

Agreed... If you've come in high of the mark and have to run down and you stop whilst doing so then that's just tough. Life is tougher when you're on port tack...
