RULES QUIZ
The US Sailing edition of the Racing Rules of Sailing for 2013-2016 has 91 rules and 184 pages. How many Right of Way Rules are there? (See answer below)

RULES QUIZ ANSWER
There are four right of way rules (All on Pg 8), four limiting rules (Pg 9), plus rules governing mark-room and obstructions (Pgs 10-11). NorthU Rules & Tactics Seminars and Webinars take the myth and mystery out of the rules so you'll understand your rights (and obligations) in any situation. The seminars cover all the rules - new and old - with a new Racing Rules & Tactics Workbook created by Dave Perry. US Sailing Memberships and Discounts!

I have no financial interest in any of the parties above; this is just FYI to improve rules understanding and compliance. I have ordered and received Dave Perry's excellent book explaining the 2013 -2016 Right Of Way rules. There is a significant savings if you order from US Sailing at the member price, and even more if you order for friends and share the shipping.
