ALL oared boats need to follow the revised crossing arrangement going upstream 

See PLA events calendar: http://www.pla.co.uk/Events/Annual-Events-Calendar
Please follow officials' advice (when present). We will have officials at the revised crossing and the PLA mooring during the period that the revised arrangements are in place (if there are no officials in attendance please use the normal navigation rules).

EXTERNAL OARED BOATS - we will only have the revised navigation arrangements in place for the final marshalling phase and the actual race (there is a considerable time between each race when there are no crews there and the navigation reverts to normal). 
We will reduce the amount of time that the revised navigation arrangements are in place for in order to reduce the inconvenience to other river users, and this year will not commence the revised navigation arrangements until the time of the first klaxon (about five minutes before the race start). Before that time boats will continue to proceed upriver in the Surrey inshore zone (please be aware of the increased traffic and keep a good lookout).
If you have been asked to take the revised crossing at Brentford Lock by the race official stationed by the moored boat with the black and white arrows there will be a further official at the PLA mooring to assist your safe passage in this area.

There may be vessels moored at the PLA moorings. 

It is possible that crews will be able to pass between the PLA mooring and the wooden post ('red' route shown below) or between the wooden post and the Middlesex bank with care ('yellow' route shown below). It may be necessary to move carefully out in front of the mooring to move round it  ('blue' route shown below).
Please follow the marshal's instructions at this point and take great care.

Please note that this applies to all oared boats, not just competitors.
