Ship's different movements in sea - explanation with diagram - Surging, Swaying, Heaving, Rolling, Pitching and Yawing -

Here is the answer for the question ' What are the different types of movements or motions of ship at sea?'

Ship has 6 motions at sea- 3 linear motions and 3 angular or rotational motions

Linear motion Rotational motion

Surging is motion along the longitudinal axis. 

Rolling is motion around the longitudinal axis.

Swaying is motion along the transverse axis

Rotational Motions

Pitching is motion around the transverse axis.

Heaving is motion along the vertical axis.

Yawing is motion around the vertical axis.
