    Rowing: London Tideway River Thames navigation & steering for coxswains Rowing: London Tideway River Thames navigation & steering for coxswains Presentation Transcript

    • Learning how to become an independent navigator and independent boat master on the Tideway So you are safer on the Tideway So coaches can coach and not “herd cats” Intelligent SatNav Skilled driver – steers/cox TSS & AKRC
    • Self- teaching • If you are working through this presentation on your own you may like to see at the same time • Basic Principles of Tideway Navigation (a single sheet) http://www.pairshead.co.uk/Tideway%20Code%20-%20pocket%20guide.pdf • 70 page Rowing on the Tideway by PLA & TRRC 2009 (booklet) or see http://www.pla.co.uk/pdfs/maritime/THE_ROWING_CODE.pdf • PLA Upper Thames Navigation Video. Go to http://www.boatingonthethames.co.uk/ and see “Safely navigating in the upper tidal Thames” • The presentation is in two parts – Tideway Navigation (Part 1) – slides 4 - 33 – Mastering the boat in the conditions (Part 2) – slides 34 – 51
    • The most important rule • Keep a good look out • In all collisions and most accidents the first finding is that those involved didn’t keep a good enough look out • Do not assert your “rights” – Assume ignorance, incompetence, distress or stupidity • Your right is to avoid collisions ? Every 5 strokes, or less
    • Tideway Navigation – (Part 1) • Definition and geography • Port and Starboard • Keeping to starboard side of fairway • Passing port to port • Shouting • Restricted zones, overtaking, rowing abreast • Using the inshore zone (slacks) • Crossing at 90o, pointing at 45o • Lights on bridges and boats • Dealing with washes • Priority of vessel types • Horn blasts • Summary and documentation
    • Mastering the boat in the conditions • Using the stream differential to – Turn or not – Turn in and out of fairway • Passing spits • Boating at different states of the tide • The yellow peril, new rules at Putney • When the differential is not your friend • Steering 8+ and 4s • Outing plan – Boat speeds – Wind direction and strength (Part 2)
    • 6 Tideway definition & geography •Just this stretch of the river •Need to know the language and geography •Study the “Basic principles” sheet and 66 page booklet Lets do the geography test
    • Barnes bend Chiswick Steps crossing Isleworth Ait Oliver’s Island or Ait Barnes bridge Corney reach Kew [road or stone] Bridge Pink House [or Lodge] Black Buoy (Putney moorings) Crabtree reach Kew pier Putney [road] bridge Boat Race finishing post Dove pier Kew Railway [or Iron] Bridge Putney crossing Brentford Aits Fulham football ground MAA boathouse Ship crossing Brentford dock or marina Hammersmith bend Middlesex Surrey Chiswick bridge Hammersmith bridge Mile Post Syon crossing Chiswick Eyot Harbourmaster’s [pontoon] Mortlake (OR Stag ) brewery Syon reach Chiswick pier RNLI station Harrods [wharf] Mortlake reach UL boathouse
    • Some definitions • Ebb (falling 7- 8+ hours), Flood (rising 4+ hours) – Where does the tide first change? • Fairway – >1m depth at low(est) tide • Inshore zone or slacks – too shallow for big vessels • Vessel: carries persons or goods – Vessels < 20m must not impede large vessels • What types of vessels are on the tideway? Class 5, cruiser, rib, barge, tug, RNLI, Fire boat, PLA / Environment Agency catamaran Rowing boats, kayaks, canoes, paddle boards, dragon boats, gig, wherry, gondola. Sailing dinghy, yachts, windsurfs Coaching / umpires launch, stake boat, start boat, slipper launch Putney An 8+ is 17m long
    • Port and Starboard Starboard – the right hand side of the boat and cox Port – the left hand side of the boat and cox Port wine is red! But the rowers right hand But the rowers left hand c o x To move to starboard side of fairway pressure up with right leg It’s the boat that has a starboard and port side - a bow and stroke side The oar loom has a red band The oar loom has a green band
    • Sample test questions from TRRC 54. Which of these is responsible for the boat during the outing? a) The coach of a junior crew where the cox is under 16 b) Stroke c) The most experienced rower in the crew d) The cox’n or steersperson 55. As a steersperson are you legally responsible for the conduct of your craft and crew? a) Yes b) Yes, unless they’re older than you c) Not if you’re instructed by a coach d) No
    • Symbols used Fairway Foreshore - Surrey Foreshore - Middlesex Inshore zone or slacks Inshore zone or slacks Poor position • The stream • Any club boat • Your club boat • Crossing the fairway • Boat in poor position • Boat moving to starboard • Boat in wrong position • Boat moving to port • Motor driven boats • Parked boat Your club boats wrong wrong
    • ColRegs (IRPCS) Fairway Foreshore - Surrey Foreshore - Middlesex Inshore zone or slacks Inshore zone or slacks Class V port starboard starboard port • Class 5 in narrow channel: 2 m/s 1 m/s 1 m/s • Navigate to prevent collisions • Starboard rule – Keep to the starboard side of the fairway and pass port to port • Rowers use the slacks when against the tide you may need to move to port - early Cannot move to starboard
    • 5. When travelling downriver against a flood tide on which side of the red navigation buoys should you pass? a) Middlesex Bank b) Surrey Side of the greenbuoys c) Middlesex side of the red buoys d) Surrey side of the red buoys Sample test question from TRRC
    • Shouting to prevent collisions • When? From Where? To Who? By Who? • What to say when – Risk of collision – “Take a look” – Collision seems imminent – “Look ahead” “Ahead” – You should stop now – “Hold it up – lightly” – Stop or you will collide – “Hold it hard” • Assume others cannot see you – Especially scullers & rowers, Class 5 and cruisers Usually, not always, people will thank you! Apologise if you were part of the problem e.g. baulking, crossing late, in the wrong position Anybody any where
    • Restricted Zones around bridges Foreshore No stopping in the inshore zone or fairway but can overtake • Only two crews side by side (rowing in a controlled manner) • No overtaking of any kind (has caused accidents) • Inshore zone: no stopping , but can overtake, no rowing abreast • You can stop to disembark • No crossing No overtaking of any kind Restricted zone Only two crews side by side No crossing Can stop to disembark B R I D G E No rowing abreast Inshore zone Inshore zone
    • Special case: Hammersmith at very low tide Middlesex Foreshore Return to IZ • If you cannot use inside arch as no water • Proceed with caution close to port side of middle arch • You have passed Starboard to Starboard! Restricted zone B R I D G E Ease out early to see oncoming crews and be seen. Shout if needed Get in line with the stream before bridge Pass through quickly in the yellow area Do not proceed if congested B R I D G E
    • Special case: Kew rail bridge at very low tide Middlesex Foreshore • Restricted zone full width of river (also at Kew Road bridge) ?? • If cannot use inside arch as no water • Turn back or proceed with caution • So if you misjudge you can turn in this restricted zone! Restricted zone Oliver’s Ait B R I D G E Do not proceed if congested If insufficient water inside buoys spin turn back Spin turn back or proceed with caution Do not proceed No overtaking in slacks
    • Overtaking rules Foreshore Foreshore Inshore zone or slacks Overtaking on the outside normal No overtaking two abreast • In general on the outside i.e. in the faster stream • Overtaking crew does not have right of way • Overtaken crew to maintain course and speed and not baulk No overtaking if you will move into oncoming craft overtaking on the outside normal Unusually overtaking on the inside as overtaken crew not close to bank
    • Rowing Abreast rules Foreshore No rowing two abreast Maintain starboard station, can overtake if safe Other crew overtaking if safe • Not in the slacks unless overtaking • Not if it will obstruct other traffic • In the fairway – Maintain a starboard station, can overtake one crew if safe • Can overtake crews who are rowing abreast if safe
    • Using the slacks • Rowers should use them – when going against the stream • Keep as close to the bank as practicable – 1m – if by a wall – 20m say – if in shallows • Boats should overtake on the outside! • So keep close to the bank if slow or stopping • It means you have to cross the river sometimes Don’t run aground
    • Crossing at 900 , pointing at 450 • River flowing at 4 knots = 2 m/s • To cross at 90 pointing at 45 boat needs to make 2 m/s against the stream so boat speed needs to be 2.83 m/s • This is a good light paddling or novice crew speed. (racing at 5 m/s = 6:40 2k) • A boat racing towards you on the stream is travelling at 5+2 = 7 m/s so if it is 70 m away it will reach you in 10 sec • To cross 50 m fairway will take you 25 sec! How long does it take to cross a 50m wide fairway flowing at 4 knots if you are crossing at 90o, pointing at 45o and on a light paddle? Stream 2 m/s Crews in the fairway should maintain course and speed ? 45o
    • Crossing Points 1. Putney crossing 2. Chiswick steps crossing 3. Chiswick bridge crossing 4. Syon crossing • Cross to get to the inside of the next bend • No stopping in crossings
    • Other crossing points? Where clubs on Middlesex have to cross fairway to the slacks UL boat house •ULO/Tyrian/Team Keane •IMM/RUM/SBA/SHG/UNH •QMC/RHO/UCL •LYR TSS/KCB/QBC/MAABC Latimer/Sons of Thames AKRC/FSC
    • 24. When crossing the river at a crossing point who has right of way? a) The boat crossing b) Class V Passenger boats c) The boat travelling in the fairway d) The larger/faster boat 25. Which of these pieces of guidance is not correct with regards to crossing the river when travelling against the stream/tide? a) Keep moving to avoid interrupting your work. b) Cross as quickly as possible (aiming to cross as close to 90° as possible) c) Cross only within designated crossing zones d) Give way to boats travelling with the tide Sample test questions from TRRC You can cross to boat and return to your club
    • Lights on bridges and boats Straw open Headroom Reducedclosed 360o white light 360o white light Flashing 360o white light recommended now If above 7 knots: 360o white light 1m above side lights, 30 cm above drivers head 180o side lights
    • 18. Approaching Kew Road bridge, rowing upstream against the tide, three scullers in front of you stop. Your view beyond the pier and the bridge is restricted. What should you do? a) Paddle out slowly and move round the scullers then go through the Surrey arch b) Move out and paddle through the centre arch once you can see it is clear c) Wait for them to move, or ask them to move. d) Keep paddling towards them as they are obliged to get out of your way 19. You are going with the tide. You wish to take your splash-top off before doing a piece of work. Where would it be safe to do this? a) Under the centre arch of a bridge b) It does not matter c) At a crossing point d) Close to the starboard edge of the Fairway Sample test questions from TRRC
    • Dealing with washes Fairway Foreshore - Surrey Foreshore - Middlesex Inshore zone or slacks 2 m/s 1 m/s 1 m/s • The cruiser going too fast • The RNLI on a rescue – blues and twos • The Class V RLNI Class V drawdown (tsunami) before the wash Especially 1x & 2x Especially 4x and 8+,blades in safe position Which way should you point?
    • Priority of Vessel types • Sailing – paddling - motor at sea • “a vessel must not cross or enter a fairway so as to obstruct another vessel proceeding along the fairway” • When do motor vessels have priority over rowers? – Emergency services with blues and twos – A Class V – A any vessel manoeuvring with difficulty e.g. at low tide – A coaching launch involved in a rescue – Ferry crossing the fairway? – A seaplane? • She should keep clear of other vessels
    • Sample test question from TRRC 40. In which four situations does a motor vessel have priority over a rowing craft? a) RNLI vessel at all times. b) Police vessel at all times. c) Any emergency vessel with blue lights flashing. d) Class V vessel in a restricted channel. e) Any emergency vessel at full speed. f) Fire vessel at all times. g) A any working vessel manoeuvring with difficulty. h) A coach launch involved in a rescue.
    • Horn blasts • 1 short blast • 2 short blasts • 3 short blasts • 4 + 1 short blasts • 4 + 2 short blasts • 5 short blasts • 1 Long blast • 2 long +1 short • 2 long + 2 short • I am altering course to starboard • I am altering course to port • I am operating stern propulsion • I am doing a 180 to starboard • I am doing a 180 to port • I am not clear what you are doing • I can’t see clearly but I’m proceeding • I’m overtaking you on your starboard • I’m overtaking you on your port One second 4-5 seconds
    • Basic Navigation rules summary • Going against the stream (working the slacks) – Use inshore zone, inside buoys, close to bank • Going with the stream – Stay in the fairway, on starboard side – With oncoming craft pass port to port – At low water a big vessel may take up the whole channel; then, if safe, pass starboard to starboard showing intentions early. • Paddle according to the direction of the stream not the tide • If in doubt keep to starboard • Do not stop, turn or overtake within 75m of a bridge (Restricted Zone) • Do not stop in a crossing zone • Always keep a good lookout, assume others cannot see you Every 5 strokes

    • Mastering the boat in the conditions • Using the stream differential to – Turn or not – Turn in and out of fairway • Passing spits • Boating at different states of the tide • The yellow peril, new rules at Putney • When the differential is not your friend • Steering 8+ and 4s • Outing plan – Boat speeds – Wind direction and strength (Part 2)
    • Using the stream differential to turn Fairway Foreshore Foreshore Inshore zone or slacks Point bows out and stream differential will turn you further In the fairway no turning effect but you might get hit If you haven’t turned by now you probably can’t! Or did you just mean to cross the fairway? - badly! 2 m/s Doing a fast 360? PLA
    • Using the stream differential to turn into the starboard fairway and pass port to port Fairway Foreshore Foreshore Inshore zone or slacks Point bows out and stream differential will turn you further as you spin turn into starboard side of fairway starboard port Passing port to port Use a sweep turn to get to far side of fairway Class 5 starboard port Turn below buoy Turn below buoy
    • Beware of spits you may end up in the middle of the river Fairway Foreshore Foreshore Inshore zone or slacks Move out early But keep out of fairway and keep moving
    • Ebb tide at AKRC – boating and return Restricted zone AKARA FSC Inshore zone or slacks St Pauls Sweep turn to get across of fairway Spin turn in slacks Restricted zones No turning, no crossing, no overtaking no stopping in slacks Use to assess timing your next move Other crews Up river out Up river return Down river out Down river return Sweep turn to get to starboard side of fairway Parked waiting to cross watching yellow peril (Dove Pier buoy) Dove Pier

    • Dove pier buoy – Yellow Peril – flood tide Restricted zone AKARA FSC Dove pier is curved! so pressure up starboard (bow) side Dove Pier Move to port to get outside Yellow peril Do not go inside yellow peril! You may have > 10 sec to get out again Check your position and pointing, especially if windy from SW
    • Putney Crossing - Ebb Tide – High Tide Restricted zone Swan Drawdock Putney Pier Fast spin turn for experienced smaller boats Yellow marker on wall by steps Safer route for less experienced longer boats in strong stream Can turn as not in restricted zone Not allowed under any circumstances, see low tide routes Crossing Zone Right Hand Rule Right Hand Rule As close to bank as practicable But right hand rule suspended ??
    • Putney Crossing - Ebb Tide – Low Tide Swan Drawdock Putney Pier Fast spin turn for experienced shorter boats Yellow marker on wall Safer route for less experienced longer boats in strong stream Move to slacker water, spin turn (against the stream) 135o then cross, or go below Rail bridge and cross Foreshore Do not cross until opposite the gap Can be very shallow here Crossing Zone Restricted zone Right Hand Rule Right Hand Rule As close to bank as practicable New Crossing Zone?
    • Putney Crossing - Flood Tide – High Tide Swan Drawdock Putney Pier All boats sweep turn across fairway to starboard side for a U turn Yellow marker on wall Can use either Middlesex arch or central arch if clear?? Proceed on starboard side as per Colregs Crossing Zone Restricted zone Right Hand Rule Right Hand Rule As close to bank as practicable On starboard side of fairway or as close to bank as practicable?

Move to slacker water and proceed on starboard side as per Colregs Foreshore Stream can be very fast here so keep moving Crossing Zone Restricted zone Right Hand Rule Right Hand Rule As close to bank as practicable On starboard side of fairway or as close to bank as practicable?
    • When the stream differential is not your friend • Attraction into the slacks as you near them • Attraction to port side if you drift into the middle • Pushed to the outside of the bend • Solution: – Keep on dancing – Adjust little and often looking round
    • When the stream differential is not your friend Different water speeds on your spoons can spin you into the slacks Drift to port and you will be swept further to port Shoal stalling the stream Keeping to starboard on a starboard bend helps Stream may sweep you to outside of approaching bend
    • Steering an 8+ or a 4+x Rudder pushes stern out, bow stays put, boat slides sideways So you need to anticipate the turn or you will go wide It’s like a rear wheel steered dumper truck
    • Steering an 8+ or 4+x A touch of starboard rudder to keep you in the slacks Keeping to starboard on a starboard bend helps
    • Your Outing plan and Boat speeds • Look up the tide times http://rjen.me.uk/thttp://rjen.me.uk/tides/Tides2012-ChisMall.pdfides/-ChisMall.pdf http://maabc.com/wp-content/uploads/2012/04/MAA-tide-tables-2012-PDF.pdf • & weather forecast & do a risk assessment & manage – Coach & Cox / steers job • Which way is the stream flowing – Pooh sticks, pontoon, bridge piers, buoys, stop and hold, paddling birds face the stream • Why normally go out against the stream? – drift back if exhaustion, injury, capsize, equipment failure (launches!) • When to go out with the stream? – Tide about to change or will change during the outing.
    • Your 90 min Outing plan and Boat speeds • How long does it take, going out coming back, if average boat speed 4 m/s, stream 2m/s, slacks 1m/s? 4m/s is elite sculler Ability Speed (m/s) Time (min) Distance (km) Destination AKRC / TSS Elite 4-1= 3 out 4+2=6 back 60 30 10.8 10.8 Pink Lodge Black buoy JM/JW / IMn /old Vet 3-1=2 out 3+2=5 back 65 26 7.8 7.8 Brentford dock Pink lodge Beginners 2-1=1 out 2+2=4 back 72 18 4.3 4.3 Chiswick bridge UL twice Faster boat classes may go further but single scullers rarely stop. Coaches usually reduce the distances
    • 52 Outing plan and wind direction Predict whether water conditions will get worse, where and when •Wind against tide makes waves bigger, especially around high water •Strong winds from SW, SE, NW, NE Show rough areasRough on flood Rough on ebb
