Under rule 86.2 and Regulation 28.1.3, World Sailing has approved the use of these sailing instructions as an addendum to the sailing instructions in World Sailing 200-Point and 100-Point Events from January 22, 2017 and until changed, for umpired fleet racing in the last race(s) of each series for the Olympic classes. Similar events are also encouraged to use the addendum. This can be done under rule 86.3 if the national authority prescribes that rule changes are allowed for the purpose of development and testing. Please note that the national authority may prescribe that such changes require its approval.
Races may be sailed under the sailing instructions in this addendum only if the notice of race and the sailing instructions so state, with reference to the relevant version, and that version is posted on the official notice board.
Use of this addendum is recommended for races in which about ten one-design boats compete with umpires present. There should be one umpire boat for every three or four boats in the fleet.
When Addendum Q is posted on the official noticeboard, this paragraph and the three paragraphs above should be deleted. Nothing below should be changed or deleted.
