1. WAKE CONTROL Umpire boat wake – a subject of increasing importance
Wake from ‘returning’ Umpires can be minimized

2. 1. STANDARD RACE FOLLOWING
START
Two chase boats at the start area
Typically, Principal Umpire on low side

3. STANDARD RACE FOLLOWING
START
Both chase boats follow race

4. STANDARD RACE FOLLOWING
START
At the finish Principal Umpire completes the race procedure
Secondary Umpire waits at the finish area until race procedure is completed

5. STANDARD RACE FOLLOWING
START
Both Umpire boats return in tandem at speed
Centre of course to equalize disturbance across lanes

6. STANDARD RACE FOLLOWING
START
When necessary, stop, turn at right angle to clear course at ‘trickle’ speed

7. Some wake facts!
Regardless of boat speed or size, wake will form at an angle of degrees to boat centerline
If returning in lane 1 of a 6 lane course, your wake will not clear lane 6 until 250m behind you - and will be uneven across the lanes!
If returning up the center of a 6 lane course your wake will clear the course within 125m behind - and will be equal across the lanes.

8. 2. MODIFIED STANDARD RACE FOLLOWING
START
Two chase boats at the start area
Typically, Principal Umpire is on low side

9. MODIFIED STANDARD RACE FOLLOWING
START
Both chase boats follow race until Principal Umpire waves off secondary

10. MODIFIED STANDARD RACE FOLLOWING
START
Principal continues to follow race
Secondary returns at low speed to start area

11. MODIFIED STANDARD RACE FOLLOWING
START
Principal completes the race procedure …
…then returns at high speed in center of course

12. Two chase boats at the start area Principle Umpire on the high side

As race passes, each Umpire moves up one position at ‘trickle’ speed
Umpires along the course support the Principle Umpire

15. As race passes, each Umpire moves up one position at ‘trickle’ speed

16. Principal Umpire completes race …
PROGRESSION SYSTEM 2
START 4 1 5 3

Principal and Secondary follow race

18. 4. PROGRESSION SYSTEM WITH TWO UMPIRES FOLLOWING3 1
START 2 5 4
As race passes – each Umpire moves up two places

19. 4. PROGRESSION SYSTEM WITH TWO UMPIRES FOLLOWING3 1
START 2 5 4
As early as possible, Secondary Umpire starts their return at ‘trickle’ speed
Primary Umpire completes race procedure

20. 4. PROGRESSION SYSTEM WITH TWO UMPIRES FOLLOWING3
START 1 5 4 2
Primary Umpire completes race procedure and moves to first position at ‘trickle’ speed
Secondary Umpire continues up to second position
If you are on the course and two umpires pass, move up two positions!

System to be used is set by Chief Umpire for each regatta
