Overlap is established at the 2 boat length circle. FYI, it does not matter if the overlap is broken inside the circle... If the inside boat came into the circle with an overlap, then room to round in a seaman like way needs to be given regardless. Bouy room will overide Port / Starboard inside the 2 boat lenght circle.
Additionally, how much room does anyone owe a single handed spin sailor who is trying to do 3 things with 2 hands?

Answer - Enough for him to make a bouy rounding as he would do without other boats around (Without f#$K ups)
At the speeds we travel though, I would be calling for room well before the 2 boat lenght circle. However it does not come into effect until the 2 boat lengths
