Situation 1 & 2
DEFINITION - Clear Astern and Clear Ahead; Overlap
Blue and Yellow are overlapped
Blue and Green are overlapped
Is Blue between Yellow and Green?
So Yellow and Blue are overlapped and Blue and Green are overlapped. So Yellow and Green are overlapped as Blue is between them, however briefly, and with no other factors present, it would appear to have little significance. However if Yellow was entering the zone of a mark while Blue was exiting the mark, it could give Green mark room, even if the overlap is subsequently broken.
John
Yes, Blue and Green are overlapped
That is pretty clear... But what about Yellow and Green? Is Blue "between" them to comply with the definition "Overlap" or not?
In the diagram below I drew a line between the boats bows and another between their sterns, any boat that touches the blue shaded area is between the boats. Or... the way I remember it is, if you can draw a line from Yellow to Green and it touches Blue, then Blue is between them, otherwise she is not.
The two seconds' transience of (Blue) overlapping (Yellow and Green) sailing in the opposite direction cannot reasonably be found as Fact in a hearing unless both agree to the timing.
Edit:
Therefore, per 18.2.e, it shall be presumed that (Green) did not establish an overlap.
Mark, what about the "space" "between Y and G" as per the pic below?
Something similar (with an unclear convention about parts of the geometric plane) was at the table with the starting line (and its extensions.)
They apply to boats [<-] (on opposite tacks) only [^] (when rule 18 applies between them) or [v] (when both boats are sailing more than ninety degrees from the true wind).
The common order of application is compliment, conjunction, disjunction, implication; so this sentence is equivalent too:
To be overlapped boats, either:
1) Rule 18 applies between them and they are on opposite tacks
2) They are both sailing more than ninety degrees from the true wind.
They are not overlapped as:
1) None of them is in the zone,
2) Blue is not 90 degrees from the true wind
I am not sure and so I support the doubt of Vladimir, who came with an interesting moment.
Is it boy in green shirt in between boys with red and grey shirt? No.
Read the entire definition of Clear Astern and Clear Ahead; Overlap, which is below with sentences numbered.
Vladimir's question was simple "Are Yellow and Green overlapped through Blue between them?" and there were two situations in the diagram.
