LBB: Length from
bridge to bow.
RODE: The length (line to the anchor) of the rode from the bow pulpit to the anchor.
DEPTH: The water depth over the anchor.
FREEBOARD: The distance from the deck at the bow pulpit to the water.
RODE: The length (line to the anchor) of the rode from the bow pulpit to the anchor.
DEPTH: The water depth over the anchor.

20)
Calculation the length of anchor chain?
A. Number of Shackles = 1.5 * SQRT(D).
(D= Depth in metre) B. Length of Cables
(in metre) = 6 to 10 * (Depth in metre).
C. Length of Cabled in moderate sea (in
metre) = 3 * (Depth) + 90 metre.
D. Length of Cabled in rough sea (in
metre) = 4 * (Depth) + 145 metre.
21) H =
water height; d = ship draught; UKC = under keel clearance; Then Shallow water
when:

C. (H/d)>=1.5 D.(H/UKC)>=1.5
22) B =
Breadth of ship; T = Ship’s draught; H = Water depth; W = Width of canal; Cb
= Block coefficient; V = Speed. SQUAT Calculation as following:
A. Block Coefficient should be between
0.5 to 0.9 B. 
should be between
1.1 to 1.4
should be between
1.1 to 1.4
C. In confined waters (ship in
rectangular canal) 
D.

23) Man
overboard: The officer of the watch have to do initial reactions:
A. Release a lifebuoy and smoke signal
on the side man overboard reported on.
B. Manoeuvre as per
recognised techniques and with due regard to the prevailing circumstances and
conditions. If the man has just fallen overboard then always place the helm
hard over in the direction that he fell overboard. This helps prevent injury by
clearing the stern away from them
C. Sound three
prolonged blasts on the ships whistle and sound the general alarm. Use should
be made of the ships P.A (public announcement) system to inform the crew of the
nature of the emergency and to indicate which side the man has fallen overboard
D. Place MOB marker on
ECDIS/GPS and other electronic navigation aids.
24) Man
overboard: The officer of the watch have to do continuous reactions:
A. As soon as possible
appoint a helmsman and activate hand steering.

when observed.
C. Liaise with the
engine room, instruct stand by engines and ensure all engines are brought
online
