Hi

Does a starboard running boat have any right of way over a port running boat that is also the inside boat at a gate mark of a course?

If no, then why does a starboard tack boat have right of way against a port tack boat at a windward mark?

Thank you for your help

Does a starboard running boat have any right of way over a port running boat that is also the inside boat at a gate mark of a course?

Yes, stbd has ROW but gives mark room to an inside overlapped boat if they are rounding the same end of the gate.

If no, then why does a starboard tack boat have right of way against a port tack boat at a windward mark?

There are some some exceptions in R 18 where mark room is not given. They are listed in R 18.1.

As it is a beat to windward, R 18.1.a says R 18 Mark room does not apply, and the port tack boat is not entitled to mark room. Just R 10 apples.

If you would like some homework, there is an article on the downwind gate in the Seattle IOM Newsletter June 2014 issue - starting at page 28.

Also there is an article on the windward mark in the October 2014 issue, starting on page 29

I have read the articles and they are very clear and informative. I have also started reading the other articles in the other editions. I recommend them as a good read.
