There are three new cases in the Supplement that are interesting and very applicable to RC sailing. and are worth reading in full.

CASE 123
Rule 10, On Opposite Tacks
Rule 14, Avoiding Contact
When it would be clear to a competent, but not necessarily expert, sailor at the helm of a starboard-tack boat that
there is substantial risk of contact with a port-tack boat, the starboard-tack boat breaks rule 14 if contact occurs and
there was still time for her to change course sufficiently to avoid the contact.

CASE 125
Definition, Obstruction
Definition, Room
Rule 19.2(b), Room to Pass an Obstruction: Giving Room at an
Obstruction
Rule 21(a), Exoneration
When an outside overlapped boatis required to give room to one or more inside boatsto pass an obstruction, the
space she gives must be sufficient to permit all the inside boats to comply with their obligations under the rules of
Part 2.

CASE 132
Rule 18.1(a), Mark-Room: When Rule 18 Applies
Rule 42.3(c), Propulsion: Exceptions
A boat is ‘on a beat to windward’ when the course she would sail to finish as soon as possible in the absence of all
other boats is a close-hauled course or above.
Question
The phrase ‘on a beat to windward’ is used in rules 18.1(a) and 42.3(c).
When is a boat on a beat to windward?
