propeller size

diameter and pitch

1

ground tackle

anchoring equipment

2

bilge

place where fumes are most likely to accumulate -- area between lower boat deck and hull

3

headway

forward motion through the water

4

bollard

post or piling

5

cavitation

rapid boiling of water, adjacent to a propeller

6

bitt

device (on the boat) to which an anchor line is secured

7

shackle

device (at the anchor) for attaching a rode (anchor line) to an anchor

8

yaw

swing from side to side about a vertical axis -- twisting left and right and left and right and left and right....until you puke

9

pitchpole

turn end over end --- bury the bow in the water while a big wave makes the stern flip over the bow -- a boatersault fun in a kayak but not otherwise

10

An exhaust blower should be run for 4 minutes before starting an engine to

remove fuel vapors from the bilge

11

The propellers of small outboard motors are protected from damage by

shear pins

12

Check gasoline fuel lines for leaks

before each use of the boat

13

While fueling a boat with a built-in tank

close all cabin doors, hatches, and ports before you begin --- to keep fumes out of the boat.

14

After fueling the boat, you should always

check for fuel fumes in the engine and tank compartments.

15

When you start your outboard motor, check to see that water is coming out of

the telltale --- a little hole on the motor that squirts a stream of water so you can tell that the cooling system is working.

16

When you refuel a portable tank

do it with the tank on the fueling dock

17

When loading your boat, consider

sea state and weather,
the activity you expect to engage in,
the weight of equipment, fuel, food, and other gear

All of the above!

18

The best way to go through shallow water with a stern drive or outboard is to

raise your motor or lower unit slightly and proceed at idle (slow) speed.

19

If you tuck your outboard or outdrive in too much (lower it too far so that the thrust is pointing somewhat downward), your boat may

plow --- push the bow down into the water

20

When viewed from aft, most boat propellers

are right handed ---- which means that they turn clockwise

21

When the pressure on the flat side of a propeller's blades is reduced, the water boils and may damage your propeller. This is called

cavitation.

It also reduces thrust and the propeller speeds up due to loss of water resistance.

22

An outboard or a stern drive tilts up or down to adjust its

direction of thrust.

- trimming the bow up or down

23

When leaving a pier in an boat with an outboard or stern drive engine with a wind or current pushing you toward the pier

it is usually easier to back out slowly until you are far enough away from the pier to turn and go forward

24

If you are turning in a narrow channel and have a strong wind on your stern

hug the RIGHT side of the channel, turn your helm all the way to the opposite shore, and BACK down

25

For normal scope, the length of the anchor rode should be

SEVEN times the depth of the water

26

To minimize the violent pitching motion when running into a heavy sea, point your bow

about 45 degrees to either side of the direction from which the waves are coming

27

When caught in severe weather, you should

reduce speed and head for the nearest SAFE shore

28

If your vessel runs aground, you should

check for leaks

29

The size of a propeller is

its pitch and diameter
