RaceSense RRS changes
[NP] Rules and Instructions for Using the Vakaros and RaceSense System
RS.1 Each boat shall have a working Vakaros Atlas 2 or Atlas Edge configured for RaceSense
at check-in. This shall be mounted as required by the OA or class at all times while racing.
RS.2 Competitors shall
a) calibrate their Atlas 2 or Atlas Edge before registration/check-in. It is the responsibility of the
competitor to ensure their device remains in proper calibration throughout the event.
b) Turn the Atlas 2 or Atlas Edge off after sailing each day. Battery life is approx. 100 hours
RS.3 The Vakaros RaceSense system will be used by the Race Committee (RC) and the
relevant information will be available to all boats.
RS.4 Instructions for using the electronic Atlas 2, Atlas Edge go to Vakaros Webbsite
RS.5 Competitors shall take all reasonable measures to keep the Atlas 2 or Atlas Edge safe
and operational
RS.6 The countdown to the start on the Atlas 2 or Atlas Edge from RaceSense will be the
official time. Signal flags will only be used for information purposes. This changes RRS 26.
RS.7 The visual identification of boats infringing RRS 29 and 30 by the RC is replaced with
electronic identification through the Vakaros RaceSense system, modifying RRS 29.1, 30.1,
30.2, 30.3, and 30.4.
RS.8 RaceSense will be used to call the Finish Line.
RS.9 Any alleged failure of the Atlas 2 or Atlas Edge, RaceSense system, or communication
systems will not constitute grounds to request redress by a boat or the Protest Committee. This
changes RRS 61.1(a), 61.1(c).
RS.10 If the RC vessel displays flag Oscar (Old School) with a long sound signal before the
warning signal of a race, RS.6 and RS.7 inclusive will not apply to that race. The RC will try to
call the sail number on a boat that has started early, on VHF channel 72. Any omission by the
RC will not be grounds for redress, This changes RRS 61.1.
RS.11 If the RC vessel displays flag Romeo (Re-Boot) with a long sound signal before the
warning signal of a race, Competitors shall restart their Vakaros Atlas or Atlas Edge unit by
switching it off, waiting 10 seconds and then switching it back on to reconnect to the
RaceSense network. Flag R will remain displayed for a minimum of 2 minutes and will be
removed with the next warning signal.
