  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

  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. 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. Hull TypesHandling Characteristics

  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. Propeller Diameter and Pitch

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

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

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

  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. Driving Cars and Boats

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

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

  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. Leaving dock - Wind off dock

  21. Leaving dock - Wind on bow

  22. Springing Away From Dock; Wind Onto Dock

  23. Docking - Wind Onto Dock

  24. Docking - Wind off Dock

  25. Anchor Types

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

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

  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

  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. Properly Set Anchor

  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. Getting Underway • Weighing anchor • Fouled anchor • Using boat’s power

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

  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. Broaching

  36. Pitchpoling

  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. Using a Drogue

  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. The Sea is so Large

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

  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. 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
