Next will be RUS as he can clear the bow of NOR. He doesn't have rights on NOR but I don't think NOR can manage to hit him if he tries. Speeds could vary so I might be wrong. They are obviously overlapped so NOR has rights on RUS.


Except that as I see it, the second boat around, Rus2, was probably clear ahead at the 2 boat length zone. It is only because they are rounding up that an overlap developed.

There's a two-length zone around marks and obstructions, and a boat's rights and obligations with respect to another boat are "frozen" when the first of them enters that zone. If you are clear astern of another boat when she enters the zone, you must keep clear of her until both boats are past the mark or obstruction, even if you later become overlapped inside her. (Rule 18.2)
