Sail Canada's Racing Rules of Sailing for 2017-2020 includes Sail Canada Prescriptions and incorporates World Sailing's Change #s 1, 2 & 3 issued 20 October 2016.
The Racing Rules of Sailing includes two main sections. The first, Parts 1-7, contains rules that affect all competitors. The second, Appendices A-U, provides details of rules, rules that apply to particular kinds of racing, and rules that affect only a small number of competitors or Officials.
The racing rules are revised and published every four years by World Sailing, the international authority for the sport. This edition became effective on 1 January 2017. Marginal markings indicate important changes to Parts 1-7 and the Definitions of the 2013-2016 edition.
No changes are contemplated before 2020, but any changes determined to be urgent before then will be announced through national authorities and posted on the World Sailing website (www.sailing.org).
