Study Notes

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.
