• Boat maneuvering & trimming

• Boat loading/safe conduct



Lesson Objectives (2)

• Man overboard/pre-trip checks

• Departing & returning to a dock

• Anchoring

• Towing a skier

• Adverse weather



Fueling Your Boat

• What should you do prior to fueling?



Fueling Your Boat

• Turn of engines• Close doors/hatches• Turn off electrical equip.• Extinguish open flames; no smoking• Turn off galley heaters and stoves• Instruct crew on safe practices• Ground fuel nozzle to boat prior to pumping

and keep it grounded while pumping



Fueling Your Boat

Fueling Your Boat

• Open doors/hatches.

• Run blower 4 minutes.

• Clean up fuel spills.

• Sniff for fumes.

• Have a fire extinguisher at hand.



Fueling Your Boat

• Gas in bilge

• Portable gas tanks• Fill on dock after grounding• Remove from pick-up bed and ground before

filling



Fuel Usage

• 1/3 rule for round trips• 1/3 tank for trip out• 1/3 tank returning home• 1/3 tank in reserve

• Refueling along the way• Calculate fuel consumption and allow for reserve

• 20% reserve• 10% reserve



Your Boat’s Propeller

• Diameter

• Pitch

• Size



Propeller Characteristics

• Who can describe how a twin screw propeller works?




• What is the function of the shear pin?



Shear Pin or Slip Hub

• Weak point in connection of propeller to shaft

• Breaks before drive shaft and gears are damaged.

• Propeller often destroyed first

• Carry spares




• Cavitation• bubbles of partial vacuum that appear around

blades due to a small prop

or too much pitch.

• Ventilation• air sucked down into the blades.



Propeller Selection

• How do you select a propeller?



Steering

• How does driving a boat differ from driving a car?



Steering

• Car• Front wheels steer in direction you want to go

• Boat• Stern steers in opposite direction• Use spring line to control movement



Steering

• Pivot point

• Stopping a boat



Steering

• Single inboard engines



Single Propeller vs.Twin Propellers

• Advantages?

• Disadvantages?



Twin PropellersSteering techniques

• 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



Tilt Adjustment

•



Jet Drives

• Propulsion

• Steering



Loading Your Boat

• What are some considerations?



Loading Your Boat

• Balance• Trim• Don’t overload; what sea condition• Secure load so does not shift• Safety

• No riding on gunwale, seat backs, transom or bow

• What are things to check when starting the engine?



Undocking Situations

• Leaving dock / wind and current off dock• Demonstrate




• Leaving dock wind and current on bow• Demonstrate




• Leaving dock wind and current on bow

• What if wind and current on stern?



Turning in Narrow Channel

• Wind on stern



Watch Your Wake

• May cause damage

• Obey No Wake Zones

• Liability



Man Overboard

• What actions do you take?



Man Overboard

• Sound alarm indicating which side the person fell over. (Helm turns toward that side, moving stern away)

• Deploy throw cushion or life ring.• Maintain a spotter • Turn boat around.• Approach PIW slowly with bow in wind• Engines in neutral• Prepare ladder• Retrieve PIW



Docking

• No wind



Docking

• Wind off dock



Docking

• Wind on dock



Mooring to Permanent Anchor



Anchoring

• Rode

• Shackle

• Thimble



Anchoring

• Why are anchors different?



Types of Anchors

• Spade



Anchoring

• Carry two anchors

• Use correct scope

• Check your position



Anchoring

• What is proper scope in calm water?



Anchoring

Anchoring

• Boat’s Motion

• Lowering Anchor

• Setting Anchor

• Anchor Dragging

• Signaling

• Obey the rules



Towing a Skier



Heavy Weather

• Using a drogue



Impaired Visibility

• Fog

Small Boat Safety

• Avoid moving• Keep low to move

• Wear life jacket

• Check weather

• Load boat carefully



Running Aground

• Check for leaks

• Raise outboard

• Move passengers to stern
