Boat test unit 1

The U.S. Coast Guard includes personal watercraft in the group of inboard vessels less than ____ in length.

16 feet

Although federal law requires capacity plates only on boats less than ___in length

20 feet

Personal watercraft

A small vessel that uses an inboard jet drive as its primary source of propulsion, and is designed to be operated by a person or persons sitting, standing, or kneeling on the vessel rather than inside the vessel

Step 3 of fueling boat

Do not allow anyone in your group or others at the fuel dock to smoke or strike a match

Divide has amount into to threes according to

Emergency, get out, and get back

Round bottom hull disadvantage

Has a tendency to roll unless it has a deep keel or stabilizers.

Length overall

Is the judge of what equipment can be used that must follow state law and regulations.

How is length overall measured?

Measured from tip to bow(front) in a straight line to the stern(rear) of the vessel.

Multi hull disadvantage

Needs a large area when turning.

NEVER do what when filling gas tank?

Never fill a tank to the brim—leave room for fuel to expand

Newer PWCs have what advantage?

New-technology two-stroke PWC engines are direct-injection engines and burn cleaner than conventional PWC engines.

_____ are the most common type of vessels that use a jet drive.

Personal watercraft

Why keep the nozzle of the fuel-pump hose in solid contact with the tank opening ?

to prevent producing a static spark.

A stern-drive engine is attached through a what?

transom. To a drive unit (also called an "outdrive") that is essentially the lower unit of an outboard

If your boat is equipped with a power ventilation system (exhaust blower) then ____?

turn it on for at least four minutes before starting your engine.

Why are Stern drives are known also as inboard/outboards (I/Os)?

because they combine features found on both inboard and outboard engines

Steering of most inboard vessels, except PWCs and jet-drive boats is controlled by what?

is controlled by a rudder behind the propeller.

Jet drives

use an engine to power a strong water pump, which sucks up water and then forces the water out the back to thrust the boat forward.

Put the fill cap on tightly to prevent__?

vapors from escaping

Displacement mode

planing hull, when operated at very slow speeds, will cut through the water like a displacement hull

The engine turns a drive shaft that is attached to a ___?

propeller at the other end.

Before starting the engine___?

sniff the bilge and engine compartment for fuel

Use caution and fill the tank slowly to avoid ___?

spilling fuel into the boat's bilge or into the water.

Before going out on a boat or PWC, it is always a good idea to __?

where you are going and ask them to take action if you fail to return on time.

Steering of stern-drive boats is controlled by the outdrive which does____?

which swivels like an outboard engine to direct propeller thrust.

Inboard engines

An inboard is a four-stroke automotive engine adapted for marine use. Inboard engines are mounted inside the hull's midsection or in front of the transom.

Outboard engines

An outboard is a portable, self-contained package of an engine, gear case, and propeller that is attached to the transom of a boat.

Multi hull advantage

Another example of a displacement hull, the multi-hull has greater stability because of its wide beam.

Plowing mode

As speed increases, a planing hull will have a raised bow(front),reducing the operator's vision and throwing a very large wake. Avoid maintaining a speed that puts your boat in plowing mode.

Step 2 of fueling boat

Ask all passengers to leave the boat and go onto the dock

Step 4 of fueling boat

Check to see that fuel lines, connections, and fuel vents are in good condition.

Step 6 of fueling boat

Close all windows, ports, doors, and other openings to prevent fumes from entering the boat

For extended boat stay You should leave a float plan that:

Describes the vessel,the description and license plate,their names and addresses, States where you are going, and Gives the phone number for local authoritie

Planning hull

Designed to ride up and glide on water, work like displacement hulls when at rest but ride up when faster speed, ride on top of water rather than paying aside

Impeller

Device used to pump and force water under pressure through a steering nozzle at the rear of the vessel

Jet drives propel a vessel by forcing a jet of water out the back of the vessel which_____?

Directing this jet of water steers the vessel.

Length overal

Length of the hull excluding any attachments

Displacement hull

Limmited to lower speeds, move by pushing water aside, cut through water with little propulsion

Step 8 of fueling boat

Make sure that your fire extinguisher is within reach

Not newest PWCs have what inboard engines?

Many personal watercraft (PWCs) have two-stroke inboard engines that burn oil as a lubricant along with the fuel

Step 7 of fueling boat

Remove portable fuel tanks from the boat and fill them on the dock.

Flat bottom hull disadvantage

Rides roughly in choppy waters

Never fuel at night unless it's an energy because?

Serious accidents

Rudder

Steering device, usually a vertical blade attached to a post at, or near, the stern (back) of the boat

Steering of outward boats is how?

Steering of outboard boats is controlled by a tiller or steering wheel that swivels the entire engine to direct propeller thrust.

What engines are four-stroke automotive engines adapted for marine use and are mounted inside the boat?

Stern-drive engines

Deep vee hull disadvantage

Takes more power to move at the same speed as flat bottom hulls. May roll or bank in sharp turns

How does the engine work in a inboard engine?

The engine turns a drive shaft that runs through the bottom of the hull and is attached to a propeller at the other end.

Do not tip the PWC in order to fill it all the way up.

The tank is designed to leave space for the fuel to expand. If the tank is overfilled, the fuel may expand and spill into the water.

Deep vee hull advantage

This planing hull gives a smoother ride than a flat bottom hull in rough water.

Flat bottom hull advantage

This planing hull has a shallow draft, which is good for fishing in small lakes and rivers

Round bottom hull advantage

This typical displacement hull moves easily through the water even at slow speeds.

Step 1 of fueling boat

Tie the boat securely to the fuel dock.

Step 5 of fueling boat

Turn off anything that might cause a spark—engines, fans, or electrical equipment

Planing mode

Your boat is in planing mode when enough power is applied so that the hull glides on top of the water. Different boats reach planing mode at different speeds.

What is a personal water craft?

a small vessel that uses an inboard jet drive as its primary source of propulsion and is designed to be operated by a person or persons sitting, standing, or kneeling on the vessel rather than inside the vessel.

After fueling, open the door of the engine compartment and...

and sniff to check for any evidence of gas fumes

Jet drives also may power larger vessels (jet boats) and are used commonly for ____ ?

for vessels designed for shallow water conditions

Check the entire fuel system for leaks and___?

inspect fuel system connections frequently
