Guys,
Remember the rules discussion last year that may have an impact on this situation ..... the starboard boat gets to determine/say "what is too close for my comfort" and has the right and obligation to avoid a "imminate collision" .... so port maybe trying to feel out starboard as to what is "too close" and avoid violating the RRS's and being protested.
Personally I think the more (polite) communication between boats racing is benefical in preventing collisions .... even if the hail is not an offically reconized one according to the RRS's.
I agree w/ Eric on this one .....
