It would be good to cover using transverse thrust and twin props to walk the boat. My understanding is that this is the (a?) advantage of inward turning props. For example, if you put starboard ahead and port astern you turn to port, but if you put the rudder hard over to port, this stops the turn and you have transverse thrust to port an boat will walk laterally to port
You are incorrect when a ship with a right handed propeller going forward. The bow will not go to the left/port it will do the opposite. The stern will go to port and the bow goes to starboard
I can not really express how much I appreciate your valuable time explaining about it. It has increased for sure, my knowledge and ability to make things happen easier when maneuvering ships of any LOA and GT, You are really good at explaining this!
Because of the shallow water effect, more resistance/turbulence is created at the stern pushing the Pivot point towards the aft (say 40% to 50% from the bow). So, the rudder effect on the ship's turning will be greatly reduced. Thats why the ship will have to move further than her normal 'Advance' distance, before starting to show the effect of turning, in shallow waters. Hope this clarifies your doubt.
Hi, I learn a lot about berthing from this video. Thank you very much. Could tell me which software or tools you used to make these beautiful animations.
Sir in case of left hand propeller when turning short turn around when vsl turns 120 of initial turn on giving stern movement the propeller movement will be clockwise so the bow will swing to port & stern to stbd , but at step 6 bow is turning to stbd on astern movement please advise sir
Right handed propeller (the one turning clockwise) make the bow to turn some on port even in rudder midship, so left handed turn bow to starboard even in rudder midship.
