Importance of Trim (List )

For and Aft Trim

Steering and Manoeuvring

• Lookout! – Ahead and behind

• Maintain an awareness of course and others• Maintain awareness of navigation rules• Actions to avoid a collision?

– Emergency stops; – Hold it up!– Slap, bury and turn

STEERING and MANOUEVRING

• Rudder: (Only works when boat moving)!

• Oars:– Use less or more

Pressure– Use all or some crew

members– Rowing on, or backing

down(Alternate or Spin)

• Boat Speed:- Faster = Rudder more Effective

• Water:– Stream/Tide – (Especially in

Narrow Rivers or around Headlands)

– Direction of Travel: Upstream or Downstream

– Waves and Swell– Wash from Other Boats

• Wind:– Head – Tail – Cross – Wind:Tide


Factors to consider when steering/manoeuvring

8

Steering; when to steer?• Oars – to manouevre the boat at low speeds• Rudder – when the spoons are in the water,

the rudder is less effective but has less effect on the– Balance– Rhythm– Comfort of the crew– Speed of the boat

8


Steering; how much to steer?• Steer early, little and often (not Late & alot!)• Account for the apparent delay between

applying the rudder and the boat changing course

• Move the strings or toggles 5cm in each direction

• Avoid repeatedly oversteering and correcting

Effect of water and weather conditions on steering

The following will affect the cox’s ability to steer their boat;

• Water– Stream– Currents– Waves– Wash from boats– Direction of travel; upstream/downstream

• Wind– Head– Tail – Cross

Using the stream/tide to turn/manoeuvre

Turning from facing upstream to facing downstream

• Start away from the stream/tide• Turn the bows into stream/tide• Stream will continue taking bows around

Stream/tide

Using the stream/tide to turn/manoeuvre


• Long swells are fun and the Cox can aid the speed of the boat by calling for faster shorter strokes as the boat rises on the wave. In this way the boat is born along on the crest of the wave and can attain high speeds.

• However caution is required!

Steering in Waves and SwellSTEERING and MANOUEVRING

• If the boat is heading directly into waves it can become very hard work for the rowers. The waves constantly check the speed of the boat and waves often break over the bow. In these conditions it may be more comfortable and faster to angle the boat to the waves reducing their impact.


• Short breaking following seas are much more difficult to deal with. As the boat starts to accelerate down the face of the wave the rudder becomes progressively less effective. In extreme cases the boat may yaw to one side and broach into the trough, tipping the rowers and the Cox into the surf.


Avoid the Broach !

• Coxes must make sure that the boat is kept at right angles to the following sea by anticipating the boat movement and making small subtle adjustments to the rudder. Never angle a boat down the face of a breaking wave


Steering on Rivers and Estuaries• Make sure you have a knowledge of the river flow

and sandbank formation

With the river flow• Always keep to the outside of bends never cut corners• Stay in the centre of the river• Be aware of fast flowing and shallow water• Stay in dark water

Against the river flow• Stay out of the main stream (closer to the bank)• Look for eddies in the current• Watch out for cavitation


TidesThe rise and fall of the tide, the direction and the rate of flow of the tidal stream will affect progress.

The decision as to duration and direction of the training session should take these factors into account

Recognising Mild Hypothermia

• Symptoms of Mild hypothermia (35 degrees C and below)

•Blue lips and nails•Rapid breathing•Wheezing or cough•Fast pulse•Slurred speech•Irrational behaviour•Violent outbursts

•Complaints of feeling cold and tired•Shivering•Confusion•Poor comprehension•Disorientation•Poor concentration•Pale


Moderate to Severe Hypothermia

• Shivering stops rigid; lack of voluntary motion

• Muscles become • Very slow and shallow breathing • Pulse slow/irregular • Lack of responsiveness
