Effect Of Wind On Ship Handling

Vessel Head to Wind with Headway Vessel making Headway through the water, and Heading directly into the Wind. W is now well forward of amidships, and in fact very close to P; the wind is exerting no turning moment, or sideways force, on the vessel.

Transverse Thrust

Ahead Movement of the Propeller The effect of transverse thrust whilst making an ahead movement is arguably less worrying than that of an astern movement, perhaps because the result is less noticeable.  (a) The helical discharge from the propeller creates a larger pressure on the

Stopped In this situation no forces are involved and the ship has its centre of gravity approximately amidships when the ship is stopped. Making Headway Two forces now come into play, firstly the forward momentum of the ship and secondly, longitudinal resistance to forward momentum,
