Introduction

Engines Electrical Systems Equipment for Sailboats Safety equipment Water Head Galley

Engines

Diesel preferred for long range cruising• Pros

Better reliability Safer than gasoline Fuel economy

• Cons Heavy Higher initial cost Expensive to maintain

Slide 3

Engines

Gasoline engines fine for short range• Pros

Greater power Less expensive to maintain Less noise

• Cons Fuel economy Safety concerns

Sailboat auxiliary now diesel• Since 1980, manufacturers moved to diesel• Rule of thumb, horsepower = 2X vessel

displacement/1000

Slide 4

Engine Essentials

Spare parts• Keep key items on your boat• Reduce down time• Essential if cruising in remote areas

Tools• Keep on aboard unique and common tools• Maintenance manuals• Canvas and sail repair tools

Slide 5

Electrical Systems

Modern cruising boats have AC and DC systems aboard

Direct Current (DC)• In US, 12 volt marine batteries are most

common• 6 volt, golf cart batteries also in use• Various types available

Lead acid AGM Gel

• Multiple batteries recommended for cruising• Engine alternator for recharging

Slide 6

Electrical Systems

Alternating Current (AC)• Marinas provide service with slip

30 and 50 amp service Adaptors may be necessary

• Onboard service Generators Solar Panels Wind powered generators

Air Conditioning• Both AC and DC systems• Power hungry

Heating• Many options

Slide 7

Equipment for Sailboats

Sail control• Roller furling

Both headsail and mainsail Reefing may create inefficient sail configuration Control from cockpit Electrical and hydraulic systems available

• Boom brake and preventer Increases safety when running downwind

• Lazy jacks

Boat control• Electronic autopilots (on powerboats as well)• Windvane steering

Ideal for long coastal voyages

Roller Furler

Slide 9

Safety

Legal and self preservation Life jackets/personal flotation devices Lifelines, harnesses, and jacklines

• Moving on deck can be extremely harzardous

Man over Board• Mandatory throwable flotation device• Practice drills to retrieve over board person

Life raft• Dinghy vs. raft• Review contents of raft• Practice use

Slide 10

Life Raft

Slide 11

Life raft is secured to deck and protected from weather

Safety

Emergency Position Indicating Radio Beacon (EPIRB)• Coastal cruising essential item• Personal or boat mounted• Registration

Radar Reflector• Increases reflectivity• Especially important for fiberglass or wood boats

Bilge pump• Standard on boats• Manual and electric

Slide 12

Radar Reflector

Slide 13

Note catch rain position

Safety

Fire Extinguishers• Class A for wood, paper• Class B for flammable liquids• Class C for electrical equipment• Sizes I and II• Portable units should be mounted

Slide 14

Water

Fresh water requirements for cruising• Drinking• Cooking• Bathing

Storage tanks onboard• Fixed tanks

Cleaned regularly Treatment (one tablespoon bleach to 20 gallons of water)

• Portable tanks/containers Replenish fixed tanks Small containers can be used for drinking water

Desalinator and rainwater• For extended coastal cruising

Slide 15

Head

Holding tanks for inland cruising• An alternative is the type I marine sanitation

devices are acceptable for recreational vessels under 65 feet.

• Y valves for discharge beyond three mile limit• Regular pump outs while cruising

No discharge zones• US EPA and local authorities can designate

certain bodies of water under their jurisdiction

Portable toilets

Slide 16

Galley

Storage always needed Stoves

• Compromise between speed and convenience and safety

• Various types Alcohol Liquid propane Compressed natural gas – safest fuel Diesel Kerosene Electric – safest

Refrigeration/Ice box
