BOATING SKILLS AND SEAMANSHIP Lesson 4 HANDLING YOUR BOAT Approved by DC-E USCG AuxA, Inc
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
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
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
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
Powering your boat The Prop Modifications Speed vs. Horse Power
Jet Drives PWCs …………………………. Age? OTS ………………………… Kill Switch Local Laws
Safety First • Don’t overload • Secure load from shifting • Bow, gunwales, seat backs, stern are not seats • Don’t’ Stand
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
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
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
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
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
Drop bow in rough water for comfort and damage prevention Lift bow in flat water for speed Tilt Adjustment
Wind & Current Crew Slow and easy (“Fending Off”) Lines & Fenders Docking
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
Anchoring • Boat’s Motion • Lowering Anchor • Setting Anchor • Anchor Dragging • Deck Fastenings • Checking Position
Anchor Rode • Everything between boat and anchor • Line • Thimble • Shackle • Wire Lock • Chain
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
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
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
Getting Underway • Weighing anchor • Fouled anchor • Using boat’s power
Heavy Weather The Warning Signs Radio Radar Visibility Narrow Inlets Bars Get Advice
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
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
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
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
Running Aground • Check for leaks • Raise outboard • Move passengers to stern • Try rocking boat • Place anchor astern and pull off • Call for assistance
Environmental Concerns • Follow markers • Don’t stir up bottom • Use proper anchoring technique • Properly dispose of waste • Beware of oil and fuel spills
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
