👍Thumb rule for ship construction diagram:
- Different books show a different diagram for the same type of ship, so understand the structural members of that particular type of ship and draw the structural member reasonably and label it.
- Eg,. the container ship has BOX GRIDER(Torsion box), mostly Bulk carriers have hopper tanks, oil tankers are double hull, etc,.
- Labeling the structures is very important than the drawing, so label as many as you can
- You will find some common labeling for all types of ships like deck longitudinals, side frames, center girder, side girder, brackets, lighting hole, etc,. fill the diagram with labels, which is the key to score maximum marks.

TYPES OF RUDDERS
BALANCED RUDDER:
When 25% to 30% of the rudder area is forward of thE turning axis there is no torque on the rudder stock at certain angles and such an arrangement is therefore known as a 'BALANCED RUDDER'.
UNBALANCED RUDDER:
A rudder with all of its area, aft of the turning axis is known as ‘UNBALANCED RUDDER’.
SEMI-BALANCED RUDDER:
A rudder with a small part of its area, less than 20%, forward of the turning axis is called 'SEMI-BALANCED RUDDER'.
