BOATING SKILLS AND SEAMANSHIP

• Lesson 4
• HANDLING YOUR BOAT

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

• Dont overload
• Secure load from shifting
• Bow, gunwales, seat backs, stern are not seats
• Dont 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
Tilt Adjustment

• Lift bow in flat water for speed

• Drop bow in rough water for comfort and damage
  prevention

18
Docking

• Wind Current
• Crew
• Slow and easy (Fending Off)
• Lines Fenders

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

• Boats 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 boats 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,

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
• Dont stir up bottom
• Use proper anchoring technique
• Properly dispose of waste
• Beware of oil and fuel spills

44
