Length of Boats
Instructor Notes:
Ask: for a definition of “overall vessel length”
Response: bow to transom; not including engines, swim platform, bowsprit etc.
Power Boats build before 1990 commonly bolt-on pulpits and platforms not included in the legal length
LOA = Length of hull, excluding any attachments.

Hull Types
AT REST
ALL boats displace water equal to their weight
IN MOTION
ALL boats create a bow wave
Instructor Notes:
Ask: What are the three main types of hulls?
Display Bullet one: Displacement.
Ask: What are the characteristics of a displacement hull?
Ask: What are some examples of displacement hulls?
Display Bullet two: Planing
Ask: What are the characteristics of a planing hull?
Ask: What are some examples of planing boats?
Display Bullet three: Combination
Ask: Why is this important to know?
Responses: Boats need to be used for the activity for which they were designed.

17. Copyright 2005 - Coast Guard Auxiliary Association, Inc.
Hull Types
THREE TYPES OF HULLS
Displacement = Pushes water aside - Sailboats, Trawlers, Ships (maximum efficiency at slow speeds)
Planing = Rides on top of bow wave - Runabouts, Speedboats, Jet Skis, (maximum efficiency at higher speeds)
Semi-displacement = Combination of first two
- Hull is designed to partially rise as speed increases, but does not fully plane
- Large Cruisers, Fast Motor Yachts

23. Personal Watercraft A PWC is a BOAT Personal Watercraft (PWC)
If you have not defined a PWC to this point spend some time as follows:
A PWC is a powerboat that is designed to be operated by one person who either sits, kneels or stands on the vessel. Anyone who operates a PWC is a skipper with the same responsibilities as the operator of a 40’ boat.
PWC’s are subject to the same laws as other boats with a few designed specifically for PWC’s.
Safety Lanyard – short cord for attaching ignition safety switch to your wrist or PFD. The lanyard should be attached to the driver at all times. In case the operator suffers an accident and falls overboard the lanyard will pull from its safe position thus causing the engine to stop. NEVER operate a PWC without a safety lanyard in use.
Steering Control – a means of controlling the steering nozzle (next slide)
