There's a good example in the Notice of Race for the Women's Match Race World Championship currently being held in Sweden. See below (emphasis mine).
15 COACHESI love it!
15.1 Individual Coach Boats shall not be allowed. An individual coach boat is any boat that is under the direction or control of a person gathering information or giving material support for the benefit of particular competitors either on the water or off.
15.2 Coaches may be register during registration time as per 4.1(a) for an accreditation fee of EUR 500. This fee includes access to the same social functions as a competitor. Each team may register one coach.
Only coaches with a valid accreditation are entitled to attend official meetings (e.g. Briefing and Debriefing).
15.3 The OA may provide a combined coach boat. Only coaches registered as per 15.2 are allowed on this boat.
I know match racing is a bit different from fleet racing but this is great stuff....
- No individual coach boats
- If you want a coach at the regatta at all then they must pay a hefty fee
- We "may" let the coaches watch the races from a group boat. On the other hand we might not.
Thanks to Scuttlebutt for drawing our attention to this excellent example.
