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 became
STARBOARD
4
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

Boat Power
Outboards
Stern Drives
Inboard/outboards I/O
6
Outboards
Advantages
•Easy to Service
Take up less room
•Less weight per
HP
Trim the drive
Disadvantages
•Higher RPM
•Less efficient Operation
•EPA
•May require a transom
cutout
7
Stern 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
8
Inboard 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
9
Jet Drive
•
•
•
•
Safety – no propeller
Operate in shallows
High speed
No prop walk
• More slippage
• Need power to steer
• May be noise

Utility Boats
• Prams
• Dinghies
• Inflatables
• Skiffs
• Utility Outboards

Boat Construction
• Steel
– Advantages
• Durability
• Strength
– Disadvantages
•
•
•
•
Rust, metal fatigue & deterioration
Weight
Magnetic
Electrolysis
16
Boat Construction
• Aluminum
– Light weight
– Difficult to protect from Marine Growth
– Susceptible to Electrolysis
– Good Heat Conductor
– Noisy
17
Wood
•
•
•
•
Workability
Relatively expensive
Strong but heavy
Considerable
maintenance
• Declining availability
18
Fiberglass
• 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
19
Construction Process
Hand-Lay-up
Chopped-Strand
20
Construction 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
