Racing Rules of Sailing

The Sprint and passage races will be governed, during daylight hours by the racing rules of sailing.  These were revised in 2017 and details can be found by clicking here.  Documents in relation to the racing rules of sailing can be found here.  This includes things like protest and appeal forms.


International Rules for Prevention of Collision at Sea

At all times the Flotilla, and during the hours of darkness the sprint and passage races will be governed by the International Rules for Prevention of Collision at Sea.  Further details can be found by clicking here.  The MCA regulations can also be found here.


Vessel Tracking

All vessels participating in the Sprint or passage races must carry a tracker.  This will be used to allow those at home to follow the event, provide verification of finish times and provide an additional means of calling for assistance.  Trackers will also be available for the flotilla fleet participants and each yacht is encouraged to rent a tracker.

The tracking will be provided by industry leader Yellow Brick.  Each tracker will be switched on when you collect it and should not need any interaction throughout the event, just make sure it has a clear view of the sky.

In case there are any problems you can view the user guide by clicking here.  The event viewer will go live a few days before the event and can be accessed via track.thestkildachallenge.co.uk or clicking here.


Each skipper and their crew must complete an online form advising the race authority of certain information important to the event safety.  This can be found by clicking here.

Each Yacht must also submit a race declaration to confirm to the race office their finish time at St. Kilda.  This should be completed by the skipper, signed and returned to the race office at Lochmaddy upon arrival.  Copies will be available in the race office and online here two days before race start.
