2 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

3 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

4 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

5 5 Hull Types Handling Characteristics

6 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

7 7 Propeller Diameter and Pitch

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

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

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

11 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

12 12 Driving Cars and Boats

13 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

14 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

15 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

16 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

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

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

19 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

20 20 Leaving dock - Wind off dock

21 21 Leaving dock - Wind on bow

22 22 Springing Away From Dock; Wind Onto Dock

23 23 Docking - Wind Onto Dock

24 24 Docking - Wind off Dock

25 25 Anchor Types

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

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

28 28 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 The Anchor Rode

29 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

30 30 Properly Set Anchor

31 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

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

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

34 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

35 35 Broaching

36 36 Pitchpoling

37 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

38 38 Using a Drogue

39 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

40 40 The Sea is so Large

41 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

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

43 43 Environmental Concerns Follow markers Don’t stir up bottom Use proper anchoring technique Properly dispose of waste Beware of oil and fuel spills

44 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
