Boat Length Classes Quiz

Vessel Length Classes

• Four length classes defined:
  • Less than 16ft
  • 16ft to less than 26ft
  • 26ft to less than 40ft
  • 40ft to less than 60ft

Types of Vessel Hulls

• Two basic types of hulls:
  • Planning
  • Displacement

Basic Hull Shapes

• Three primary hull shapes:
  • Flat bottom hull
  • Round bottom hull
  • Vee bottom hull

Vessel Sides

• Port side refers to the left side of the vessel.
• Stern indicates the rear of the vessel.

Engine Types

• Four basic engine types:
  • Stern drive
  • Outboard
  • Inboard
  • Jet drive

Engine Adaptation

• Stern drive and inboard engines are modified automotive engines designed for marine use.

Personal Watercraft (PWC)

• Defined as vessels operated by sitting, standing, or kneeling, using inboard engines and primarily driven by jet propulsion.
• Subject to all boating laws and specific regulations for PWCs, as well as applicable motor vehicle laws.

Impeller Function

• An impeller pumps and forces water under pressure through a steering nozzle located at the rear of the vessel.

Capacity Plate Information

• The capacity plate displays the recommended maximum horsepower rating and maximum weight capacity of an outboard powerboat.

Float Plan Guidelines

• Before embarking on an extended outing, include:
  • Number, names, and addresses of passengers
  • Number, size, and make of the vessel
  • Route, date, stopping points, and expected return time

Fueling Precautions

• Turn off all engines and electrical equipment before fueling to ensure safety.

Fuel Management for PWC

• Recommended practice:
  • Use one-third of the fuel for the trip out, one-third for the trip back, and save one-third as reserve for emergencies.

Trailer Load Capacity

• If the combined weight of the vessel and engine exceeds 90% of the trailer's recommended load capacity, a larger trailer is necessary.

Tongue Weight

• Tongue weight is the weight that the loaded trailer exerts on the towing hitch.
• Ideal tongue weight should be 7%-10% of the combined weight of the vessel and trailer.

Boater Courtesy

• Show consideration by not blocking launch lanes or ramps while preparing the vessel for departure.
