Satish' analysis looks most excellent to me.

He doesn't answer Q5 directly but effectively deals with it in his Q3 answer. If C felt they had ROW and that this somehow overrules rule 18, I suggest they read the preamble to Part A the last sentence of which says "However, some rules in Sections B, C and D limit the actions of a right-of-way boat." Rule 18 is one of those ;-) C is toast!

John, I am glad that the WASZP rules are working in practice.  I think that the wingfoils will go a different direction, with little or no limitations, at least in part because they are always in the standing position.  I think that should be up to the fleet decide and adopt in their class rules so we shall see as the class matures.

I'm with Phillip, in the definition its a measure, and that measure should be consistent. A less than competent crew is not entitled to more room than an expert one, and would be breaking a rule if they require it (lets leave room made freely available out of it for now).  Similarlty an expert crew is allowed the same room as a competent one, even though they may not need it,

John, I agree with you about reasonable apprehension and skill level, but I think its a red herring in the context of Room and Case 103.

A holywood is really a match racing term for a great show, but may not be genuine.

The world sailing judges manual changes on improper act or ommission in each version, each seeming giving judges more room for interpretation. Just track the change next time, it may be what gordon and i may expect.
The old bad race management hidden behind the word may not shall,, may not be tolerated.
A time of change perhaps! I believe for the better if we are to improve standards and improve the sport.
