Steering
•
•
•
•
race steering is not the same as training
find the fastest line
steer from the tops of the banks
big simple sweeps round the bends
• know the overtaking rules for your race

The Theory
River profile
- deepest point ≈ maximum stream
Where’s the depth?
BE
FFC
=> The fastest stream is not always
in the middle of the river
16-Jul-15
6
Silting
Lack of dredging:
- stream slows down and broadens
Useful pointers - with stream
• Know where the fastest stream is
generally
• Curve with the bends, don’t cut them
• You don’t need to steer much
• Steer from the tops of the banks, not mud
• Beware mid-stream obstacles

Chiswick to Barnes Bridge
• Centre of Chiswick Bridge
• Approximately halfway between the banks
• Don’t be drawn in towards Middlesex as you
approach Barnes Bridge
• Angle slightly towards the Mdx pier of bridge as
you shoot through it

Very low tide - note shallows on Surrey bank

12
Barnes to Chiswick Eyot
• Up to moored boats, stay same distance off Mdx bank,
past Bandstand
• Parallel to moored boats before Eyot
– approx. 1-2 widths away from them
• As the corner turns, start looking at your BS for the guide
• Parallel to Eyot - midway or slightly to SS
16-Jul-15
13
Eyot to Hammersmith
• At end of Eyot, look at Surrey bank = BS
• Stay this distance away from it (ignore Mdx
•
bank), round to St. Paul’s School
Continue at same distance
– stay parallel to BS bank
• Brings you under “second lamppost” or v slightly
to SS of it
16-Jul-15
14
Hammersmith to Barn Elms
• By now you’re 1/3 off Surrey bank - no closer
• Keep this distance away from BS bank
• Harrods Depository wall: bad water?
• Stay parallel to Surrey bank right to Barn Elms
• By Barn Elms, 1/4 off Surrey bank
– avoids Fulham Flats
16-Jul-15
15
Barn Elms to Putney Pier
• At apex of Barn Elms bend, look to Black Buoy
•
(actually half-black, half-yellow)
Let yourself re-aim to pass it just on its SS
• 1-2 widths off Buoy (pref. 1)
• Stay parallel to moorings until LRC big flagpole
• Then head for centre of Putney Bridge

After the race
• Obey marshals straight away
• No turning between Putney and
Wandsworth Bridges
• Turn before tucking in to stop and do
kit/water/etc
• You may be called in to have safety
checks at Chas Newens’ landing point

Organise now

19
Racing tactics
• motivation/coaching/steering/pushes
• not talking all the time
• getting round other crews
• planning for problems
16-Jul-15
20
Steering
• - during training is different, and much busier
• No following the racing line in training
• Stick to the bow side of the ‘fairway’ while in the
middle of the river ie with the stream
• What’s the ‘fairway’?
16-Jul-15
21
Steering in training
•
•
•
•
•
•
Know which way tide’s going
Working the slacks
Crossing points
Starboard rule in main stream
Tide turn warnings
Observe landing and crossing rules
16-Jul-15
22
Useful pointers - against stream
• Point bows slightly to bank in strong
stream
• Stick near the riverbanks
– ….. but beware mudflats/gravel islets
• Know where to cross
– ….. and give way to other crews while x’ing
16-Jul-15
23
Planning
•
•
•
•
•
•
•
weather?
kit and equipment
meeting times and locations (parking?)
READ THE ***ing RULES (!) incl. marshalling
start order
race plan and visualise
warm-up plan
16-Jul-15
24
Marshalling
• Which station? (bank)
• Near which point?
• Which crews around you?
• What time must you be there?
• => what time to boat?
16-Jul-15
25
Stuff - useful and necessary
•
•
•
•
•
•
•
•
•
Tools (i - rigging and ii - in the boat)
Kit (warm, many layers, wellies)
Race numbers (on boat and on crew)
Accurate watch (set to speaking clock)
Lifejacket, coxbox, mic, headband?
hat/cap, shades, gloves?
marshalling map?
sponge?
Two black bin-bags and a kind friend

•
•
•
•
•
•
•
ARA ID numbers
Race numbers
Hatch covers
Heel restraints

Timetable
•
•
•
•
•
•
•
Get numbers
Meet up
Rig and check boat
Crew chat
Down to boating area
Push off and warm up
In place by correct time
16-Jul-15
28
Warm-up
•
•
•
•
•
Fours
Short slide work/timing synchronisation
Steady rowing
High pressure/rate
Sitting about....
• Make use of gaps and clear stretches
16-Jul-15
29
Sitting about
•
•
•
•
•
•
•
•
•
•
•
Stay warm (all the time)
Respond to marshals
Stay clear of other crews
Bows slightly to the bank
Not stopped close upstream of obstacles
Vary who rows on
Remember you can back down to get clear
Clever manoeuvres
Amusing jokes?
Check the boat
Keep an eye on the time
16-Jul-15
30
Turning
• Don’t stay too close to the bank - let yourself
•
•
•
•
•
•
come into mid-stream
Turn when asked, and turn efficiently
Stay with adjacent numbers
Minimal backing-down gets you centre stream
Think about positioning once turned
Kit off before you turn (or during)
Psych crew up to be ready straight away
16-Jul-15
31
Racing
•
•
•
•
•
•
•
Know where you are
Know when you are
Remember the race plan
Give rowers time to think
Use other crews just enough
Consider overtaking and conditions
Racing line
16-Jul-15
32
Mental approach
• Stay calm
• Motivate both crew and individuals
• Always sound positive and focused and
keen to do well
• Track what the rowers need to remember technique, race plan, tactics, waypoints
• And always make steering a priority

33
After the race
•
•
•
•
•
•
Wind down safely and listen to marshals
Kit on after turning out of the way
Safety checks?
Stick to return lanes as you go back
Stay positive but don’t talk too much!
Cross safely if necessary - check marshals
are happy first
