17

Archimedes principle refers to

The physical law of buoyancy

18

A body immersed in a fluid is Buoyed up by the force equal to

The weight of the displaced fluid

19

A ship will displace an amount of water equal to

It’s weight, and the waterline will reflect this

20

A waterline is

Where the water intersects The hull, and Will vary depending on the amount of cargo, ballast, fuel, stores, etc.

21

Draft marks must be displayed on _____ and _________ sides, are _____ high and spaced _______

Port, starboard, 6 inches, 6 inches

22

Draft marks can be displayed

In English (feet and inches), or metric (meters and centimeters)

23

Metric draft marks are _______ high, and _______ Apart, And the start of each full meter may have a __________ Next to it

10 cm, 10 cm, M

24

10 cm equals

.1 m or 1 dm

25

_________ _________ Ensure the ship has sufficient freeboard, thus sufficient reserve buoyancy

Plimsoll marks

27

______ Is the difference between draft at the stern and draft at the stem

Trim

28

_______ ________ Is the average of forward and aft drafts

Mean draft; the main is equal to the four and after draft divided by two

29

The length from the rudder shaft to the crossing point Inside the bow plate and upper deck is the_________ ________

Registered length

30

LBP

The length between perpendiculars; (rudder shaft to crossing point bow and loaded waterline)

31

What is air draft?

Overhead clearance

32

The total weight of the ship and contents when afloat is equal to the weight of the water displaced

Given in long or metric tons

Displacement

33

Light ship displacement

Total weight of the empty ship (does not vary)

34

The difference between loaded displacement and lightship displacement is
