This month, we continue with our review of the changes in the latest rule book, 2017-2020. The hard copy of the new book is now available from Sail Canada. I hope that local stores will have it soon. It is also available on the web from the World Sailing site. This month, I will continue our look at mark roundings, this time looking at rule 18.3 “Tacking in the Zone”. Rule 18.3 has always been the part of rule 18 that is most difficult to explain. When it was first introduced, in 1997, I summarized it by saying “Don’t tack within the zone unless you have read the rule at least three times.” The new version is not much easier to understand. It does eliminate some unusual cases and limits the rule to its originally intended purpose.
