1 BOATING SKILLS AND SEAMANSHIP Lesson 4 HANDLING YOUR BOAT Approved by DC-E USCG AuxA, Inc

2 Lesson Objectives Boat handling and loading Fueling and 1/3 rule Prop selection and operation Safe boating operation Anchoring procedures About hypothermia Undocking and docking/mooring Heavy weather operations 2

3 Fueling Your Boat 1/3 rule Ground fuel hose to boat rail or gas cap Keep fumes out Prevent spills Portable tanks Gasoline in bilge 3

4 Getting Started Brief your guests Check on weather Life jackets out and ready Test throttle and steering Gas and oil check gages Engine warmed up check gages & tell tale 4

5 Hull Types Handling Characteristics 5

6 Propellers Selecting the right prop To protect prop, use: Shear pin Slip Hub Should carry on board Spare pins Spare prop Tools Guard against cavitation & ventilation 6

7 Propeller Diameter and Pitch 7

8 Powering your boat The Prop Modifications Speed vs. Horse Power 8

9 Jet Drives PWCs. Age? OTS Kill Switch Local Laws 9

10 Safety First Don t overload Secure load from shifting Bow, gunwales, seat backs, stern are not seats Don t Stand 10

11 Steering Car Front wheels steer and vehicle moves in direction you turn Boat Stern steers & back half of boat moves in opposite direction before eventually moving in direction you intend Pivot point generally 1/3 back from bow May control with spring lines Stopping 11

12 Driving Cars and Boats 12

13 Steering, Single Prop Forward gear, stern moves in opposite direction Reverse gear, stern moves in direction of turn Right hand prop has small prop walk to right in forward, larger walk to port in reverse 13

14 Steering Twin - Props Each Engine Will have Its own Throttle and Gear Controls You Can Turn Slowly by Operating One Engine Faster Than the Other Prop walk offset by one left & one right hand prop. When operating only one, remember walk You Can PIVOT in a Narrow Area by Putting One engine in FORWARD, the Other in REVERSE 14

15 Steering Techniques Twin Propellers Steer with rudder when at speed Use differential prop thrust at dock Use both rudder and thrust to walk sideways Forward on port, reverse on starboard to swing bow to starboard Since forward prop has more thrust, rudder to port with above also moves stern to starboard 15

16 Steering Techniques Jet Drive No prop; no prop walk No neutral; balance forward & reverse thrust Turns require power use burst Pivot point nearer intake; sharp turns 16

17 Tilt Adjustment Lift bow in flat water for speed Drop bow in rough water for comfort and damage prevention 17

18 Docking Wind & Current Crew Slow and easy ( Fending Off ) Lines & Fenders 18

19 Docking or Undocking Where is wind? What is its effect on your boat? Where is current? What is its effect on your boat? When docking Check wind & current by stopping boat. Use ample amount of neutral 19

20 Leaving dock - Wind off dock 20

21 Leaving dock - Wind on bow 21

22 Springing Away From Dock; Wind Onto Dock 22

23 Docking - Wind Onto Dock 23

24 Docking - Wind off Dock 24

25 Anchor Types 25

26 Anchoring Boat s Motion Lowering Anchor Setting Anchor Anchor Dragging Deck Fastenings Checking Position 26

27 Anchor Rode Everything between boat and anchor Line Thimble Shackle Wire Lock Chain 27

28 The Anchor Rode Rode Name For the Line and All Associated Gear From Boat to Anchor Chain Connects between Anchor and Line Prevent Chafing of line on Bottom Recommended use of nylon line Stretches as wave action lifts vessel Acts as a shock absorber 28

29 Deploying the Anchor Find a protected spot Head Your boat Into wind/current Stop Boat Lower the anchor until it reaches bottom Back slowly while letting out the Line Normal Scope: 7 TO 1 If Depth is 10 ft Scope is 70 ft 29

30 Properly Set Anchor 30

31 Raising the Anchor Head the boat toward the anchor Go head slowly, hauling In the Line Stop Boat when Over Anchor (Line is Straight down) Lift Anchor Slowly Use Care Prevent the Anchor From Bashing against the Hull 31

32 Getting Underway Weighing anchor Fouled anchor Using boat s power 32

33 Heavy Weather The Warning Signs Radio Radar Visibility Narrow Inlets Bars Get Advice 33

34 Underway Preparation Heavy Weather Close topside openings Pump out bilges Secure loose gear Put on life jackets Break out emergency gear Check / update position Look for shelter Instruct crew 34

35 Broaching 35

36 Pitchpoling 36

37 Yawing Unintended turning of boat due to slow speed or loss of rudder contact with water at crest of wave May require considerable engine power to overcome once prop & rudder back in water 37

38 Using a Drogue 38

39 Operating in thick Weather Operate at a Safe Speed Need to: See and be seen Hear and be heard Use: Lookouts forward Passive radar reflector 39

40 The Sea is so Large 40

41 Safety at Sea Equipment You get what you pay for Knowledge and experience You are here Common sense Know when to go and when not Have a plan MOB, Medical Emergency,Spill, Lost, Out of Fuel, Mechanical Failure, Fire At Sea, and Sinking 41

42 Running Aground Check for leaks Raise outboard Move passengers to stern Try rocking boat Place anchor astern and pull off Call for assistance 42

43 Environmental Concerns Follow markers Don t stir up bottom Use proper anchoring technique Properly dispose of waste Beware of oil and fuel spills 43

44 Summary Fueling procedures The propeller Driving boat vs. car Twin vs. single screw handling Tilt adjustments Loading the boat Getting started Leaving pier and docking Mooring and anchoring Heavy weather 44
