operation of launch outboard motor
1. Unscrew the winged knob on petrol tank and squeeze bulb
in petrol line until it is full of petrol (i.e., hard)
2. Large lever is gear lever and accelerator combined. Put
it in neutral (vertical)
3. The small lever is an accelerator only, and is only used
for starting in particularly cold conditions - it should
normally only be necessary to use the choke. To
operate the small lever, push it forward, past the
4. Engage the forked end of the kill cord onto the kill
5. Pull out choke on engine
6. Pull cord to start engine
7. Once the engine has started, push in choke on engine, and
return the small lever (if utilised) to the off position
(fully back and down)
8. Check that a small stream of water is coming from under
the cowling at the back of the engine. If not, clear the
outlet with the stiff wire provided or summon help. If
you can't get the water to flow, switch the engine off
9. Engage gear by moving the gear shift forwards for
forwards, back for reverse
10. Once the gear is engaged, push the lever further forward
in the same direction to accelerate
11. To stop the engine, put it in neutral and remove the kill
cord from the kill switch. Screw down the winged knob
on the petrol tank

small lever in down position]
Service launch operation and handling notes
BEFORE you let the launch down the slipway into the water, make sure that (1) the BUNG is securely in place at the bottom of the transom (the boat will SINK without the bung!), and (2) the mooring ropes are securely fastened to their respective bollards or rings (you don't want to have to swim after the boat as it drifts under Rainbow Bridge!). Loosen the black air vent screw on the top of the tank cap, remove the cap, and check the fuel level. If the tank is LESS THAN HALF FULL, ask the Race Officer (OOD) to get it filled up for you. REPLACE THE FILLER CAP SECURELY, and close the vent.
With the launch securely tied alongside the staging, pointing UPSTREAM, or in it's usual berth at the upstream end of the staging, OPEN THE AIR VENT ONE FULL TURN.
At the ENGINE GEAR CONTROLS, ensure that the larger lever is in the VERTICAL POSITION.
On the ENGINE, check that the RED ENGINE STOP SWITCH is UP, pull out the CHOKE KNOB next to it, and squeeze the bulb in the fuel line until resistance is felt.
Pull the 'T'-SHAPED RECOIL STARTER HANDLE FIRMLY; the engine should start. If it doesn't, try ONCE MORE. If the conditions are particularly cold, it may be necessary to use the small accelerator lever: push it as far forward as it will go. If the engine still doesn't start, go through the whole procedure again. If it still won't start, GET HELP.
With the engine started, check there is a STEADY STREAM OF WATER from the starboard underside of the engine casing (left-hand side as you look at it). IF NO WATER, STOP THE ENGINE IMMEDIATELY AND SEEK HELP.
PUSH THE CHOKE BUTTON IN AND 9IF UTILISED) RETURN THE SMALL STARTING LEVER TO IT'S ORIGINAL POSITION, REARWARD AND HORIZONTAL.
When you are ready to go, with the engine running smoothly, CHECK BEHIND for dinghies and also for any cruisers approaching from up- or down-stream. Cast off the STERN rope, turn the steering wheel to STARBOARD i.e., to the RIGHT, cast off the BOW rope, put the gear lever into REVERSE, and GENTLY reverse into the stream, centralising the wheel as you go, until you are in approximately mid-stream, keeping a gOOD lookout all round for dinghies and other vessels.
Select NEUTRAL, then FORWARD GEAR, and GENTLY move off in the direction you want to go, and accelerate to a reasonable speed.
There are Environment Agency BY-LAWS concerning navigation at excessive speed and creating unnecessary wash, and the Service Launch should be driven so as to cause as little disturbance as possible to other river users. By keeping a station as close as you reasonably can to those sailors you consider to be the most vulnerable in the prevailing conditions, and therefore most likely to need your assistance, you can minimise the distance you might have to travel at high speed.
WARNING: DO NOT ATTEMPT TO LEAVE THE STAGING IN A FORWARD DIRECTION. You will only drag the propellor through the gravel bank at the upstream end of the staging, damaging the propellor, filling the engine cooling system with grit, and possibly stalling the engine in the process.
Whilst patrolling the course, keep an eye on the cooling water jet. If it STOPS, or reduces to a DRIBBLE,slow right down, make for the MEDLEY bank, STOP THE ENGINE, beach or anchor the boat, and get the blockage cleared (there is a probe in the box under the console). If conditions are quiet, you may beach the boat on the Medley bank, in a position where you can see most of the Reach. Keep the stern of the boat in the deepest water. When you move off again, push the boat into deeper water before starting the engine.
On your return to the Club, preferably moor the boat in it's dedicated berth at the upstream end of the staging. If this is not practicable, bring the boat into the staging facing UPSTREAM. Secure the BOW line first, then the STERN line, and stop the engine.
At the end of your tour of duty, land the buoys, recover the boat into the Boat Shed, remove the bung to let the boat drain, close the fuel tank vent, and leave the boat clean. Ensure that the slipway broom is put back in the launch.
Yardsticks and how to apply them
1. Work out in seconds how long each boat took to complete the race [the 'elapsed time']
2. Multiply this number by 100
3. Divide the result by the boat's py number
4. This gives the 'corrected time' for each boat (in seconds), and thus the order of finishing
