No, it applies to my previous statement "I'll go you one further and say that even if you AREN'T entitled to mark-room from (and in fact, even if you owe mark-room to) an outside/leeward boat, you CAN drive her beyond the mark. She can take you head-to-wind, but you are not obligated to tack, nor to give her room to tack."

I don't have an ISAF Case citation that is an exact match to the scenario posted, but then again, the boat entitled to mark-room tacked when she reached the layline. She didn't push the leeward boat away from the mark.

You asserted that a boat entitled to mark-room must tack within that mark-room, which is what we're discussing now. I asked you to justify that statement with a rule reference. Cases about how much room is enough, and how to interpret the term "seamanlike" are not germane.

Can you identify any rule, case, or appeal that states a boat is ever "obligated to tack and round the mark"?

Sincerely,
Eric
