Boaters Language
• Much derived from ancient sailing days
• Norwegian rudder was a “STJORN”(pronounced starn)
• STJORN BOARD was on right side of vessel – facing to front
• Right of vessel becameSTARBOARD
5
Boaters Language
• Left Side of Vessel was next to Dock (Port side) again facing front
• The Loading Board was on the LEFT side
• LOAD BOARD became LARBOARD
• LARBOARD / STARBOARD sounded too much alike
• LARBOARD changed to PORT
• PORT - STARBOARD

Advantages•Easy to ServiceTake up less room•Less weight per HPTrim the drive
Disadvantages•Higher RPM•Less efficient Operation•EPA•May require a transom cutout

Stern DrivesStern Drives
• Advantages– Quieter– Better Fuel Economy– Lower RPM– Trim the drive
• Disadvantages– More weight per HP– Loss of Deck Space– Lower unit Gearing Problems– Danger of Fire & Explosion
9
Inboard DrivesInboard Drives• Advantages
– Simple gearbox & straight shaft
– All machinery but prop in boat
– Engine centered and balanced
– Good control for skiers • Disadvantages
– Poor rudder control, esp. at slow speed & reverse– May disrupt deck space– Thrust upward vs parallel
to surface

Jet DriveJet Drive
• Safety – no propeller• Operate in shallows• High speed• No prop walk
• More slippage • Need power to steer• May be noise

Boat ConstructionBoat Construction
• Steel– Advantages
• Durability• Strength
– Disadvantages• Rust, metal fatigue & deterioration• Weight• Magnetic• Electrolysis
17
Boat ConstructionBoat Construction
• Aluminum– Light weight– Difficult to protect from Marine Growth– Susceptible to Electrolysis– Good Heat Conductor– Noisy
18
WoodWood
• Workability• Relatively expensive• Strong but heavy• Considerable
maintenance• Declining availability
19
FiberglassFiberglass
• Fiberglass layers / strands saturated with resin• Advantages
– No seams or joints– Strong– Molded into any desired shape– Low maintenance– Easily protected against Marine growth
• Disadvantages– Heavy – Heavier than water– Easy to cover up shoddy work– Resins that bind will burn

Construction ProcessConstruction Process
• Matched Die Process– Male and female molds used– Clamped together with Laminate between
• Sandwich Process– Core material covered with layers of
fiberglass– Usually Balsa Wood – sometimes Foamed
Plastics or Plywood– Strong and Buoyant
