Two-Boat Umpiring

Devised by

Bruce Hebbert

June 2007

background
Background
  • At most TR events, we do not have the luxury of 3 boats umpiring – rather, we often have only one and sometimes two umpire boats on a race
  • The following has been developed to provide a method for handling this
there are generally 2 variations
There are generally 2 variations:
  • 2 umpire boats throughout
  • 2 umpire boats at the start, with the second leaving at the windward mark
terminology
Terminology
  • Driver of Lead Umpire Boat – LU
  • Second Umpire in Lead Umpire boat- LUA
  • Driver of Second Umpire Boat – 2U
  • Second Umpire in Second Umpire Boat- 2UA
  • (Sorry about this…but if you have a better acronyme, shout now)
general principles
General Principles:
  • All Umpires follow a single team, usually those with the lower numbers are selected by the Lead Umpire (eg. the Red team)
  • The Lead Umpire (UL) for the race will take the committee boat end of the line. The other Umpire boat (2U) will take the pin end
  • The driver of the Lead Umpire boat (UL) is the controller
dialogue
Dialogue
  • When an Umpire boat is following a single ‘target’ boat, dialogue between LU/LUA and 2U/2UA is essential – the driver taking the ‘target’ boat, and the second Umpire taking the opposing boats that are nearby
  • When an Umpire boat is following two boats, each Umpire should clearly select to follow one of the two boats

2U

LU

LU to LUA: ‘I have Red 2, you have Red 3 - keep an eye on Red 1’

While all in a bunch around LU, then 2U just waits

slide10

2U

Here, when it is clear that Red 1 is moving to leeward, 2U starts to take responsibility

slide11

2U

If this happens, 2U should take both Red 1 and Red 2

slide12

LU

2U

As the boats approach the line to start, (generally) one of the Red boats will move down the line. 2U takes this one (Red 1)

LU may hail or radio to confirm that 2U takes Red 1

slide13

LU

2U

In the final approaches, LU should take the boat starting closest to the committee boat and position to see any incident. LUA should follow the other Red boat at the committee boat end

slide14

If as here… 2 Red boats go to start at the pin end, then 2U and 2UA each take one and LU keeps the committee boat end

A hail or radio call to this effect from LU is helpful to ensure this happens

slide15

In the last 15-20 seconds, Umpires must keep to their boats ensuring they know how overlaps were established

slide16

Just before and after the starting signal, an eye should also be kept on the Blue boats - especially if Rule 42 conditions exist or if one is OCS and may turn to return

slide17

After the start, Umpires should keep with their boats for the first 30 meters or so to ensure all ‘accidental’ incidents are covered

slide19

2U

LU

Thereafter, the fleet typically splits left and right.

LU should go right, 2U should go left

slide20

Despite the left-right ‘rule’, the over-riding requirement is to be positioned to cover ‘engaging pairs’

slide21

As the fleet approaches the laylines, the Umpire boats should move to be outside the laylines

slide22

On the approach to the mark, the Umpire boats must be positioned to see overlaps as boats reach the zone

slide23

LU

2U

The Umpire of the leading pair must aim to get to windward of the first mark, and hold position to see any action before turning towards Mark 2

Illustrated for LU – easier when 2U is on the leading pair

slide24

The first Umpire to the windward mark goes with the front of the fleet…keeping to windward, then going down the port of the fleet as they approach Mark 3

slide25

The second Umpire to reach the windward mark goes either high or low on the first reach, depending on the spread

slide27

The Umpires need to keep sufficiently to windward to avoid luffs… but avoid the Red shaded area

slide28

On the run, the Umpires have kept to the port side of the fleet..though the green Umpire may go either side at first

slide29

If there is any attempt at a passback at Mark 3, the Red area is a ‘no go zone’ for the umpires

slide30

The front Umpire boat moves below Mark 3 to see the action…then turns and keeps to leeward of the rhumb line 2-3

slide32

Approaching Mark 4, both Umpire boats are ideally positioned below the rhumb line…and both avoid ‘Hell Corner’ indicated in Red

slide33

On the final beat, the Umpires need again to go left and right, taking the two most in contention pairs. Whatever happens, the key ‘Gap’ must be covered. LU should hail or radio as necessary

It is often (but not always!) easier for the Umpire leading along the reach to go right up the beat, and the trailing Umpire to go left

slide34

Approaching the finish, seeing overlaps at the zones are key for E9 calls, so Umpires need to be outside the laylines…and should never cross the finish line
