SECTION 4 – Gybing at a Windward or Offset Mark
Please read the following description carefully . . .
Note: For the purpose of these questions, the definition Mark-Room has been changed to: "Mark-room is room for a boat to sail her proper course until the mark is astern of her."
In Section 4, a boat entitled to mark-room gybes near a windward or offset mark.
The following questions concern the rules at a mark that begins a run (meaning a leg on which most kinds of boats will have to sail on both tacks at some point to reach the leeward mark). Examples of such a mark are a traditional windward mark, offset mark, or the outer reaching mark of a trapezoid course.
As a reminder, if a boat is entitled to mark-room and she is sailing within the mark-room to which she is entitled, she is exonerated (not penalized) if she breaks any Section A rules (e.g. rule 10 - port/starboard or rule 11 - windward/leeward). In other words, a boat sailing within the mark-room to which she is entitled is “protected” by rule 18.
The questions below ask your opinion on whether "rule 18 protection" should end when a boat gybes at a windward/offset/outer trapezoid mark when she otherwise does not need to gybe to sail directly to the next mark. Or whether it should continue after a boat gybes if she thinks gybing is her proper course. And if it should continue, for how long should it continue?
For these questions, the mark is a traditional windward or offset mark. The next mark is directly downwind such that Boat X will need to sail on both tacks at some point to reach the next mark. Boat X is entitled to mark-room from Boat Y under rule 18. There is no damage or injury as a result of the contact.
