WHAT IS THE PIVOT POINT ON A SHIP OR BARGE?

FAR AWAY



PIVOT POINTS

AS THE WORD IMPLIES, A PIVOT POINT IS A CENTRAL POINT ON A VESSEL WHICH REMAINS FIXED AS THE BOW AND STERN SWING AROUND IT. FIXED IS NOT REALLY THE CORRECT WORD, BECAUSE IT MOVES FORWARD OR AFT AS THE VESSEL MOVES THROUGH THE WATER. IF THE VESSEL IS MOVING FORWARD THROUGH THE WATER, THEN THE PIVOT POINT IS ABOUT ONE QUARTER OF THE WAY AFT OF THE BOW, IF THE SHIP STARTS MOVING AFT, THEN THE PIVOT POINT MOVES AFT. IF YOU ARE DEAD IN THE WATER, THEN IT DEPENDS ON WHAT FORCE IS MAKING THE BOW OR STERN TO SWING FASTER TO DETERMINE THE PIVOT POINT. IF THE FORCES ARE IN BALANCE DURING THE SWING, THEN THE PIVOT POINT IS AMIDSHIPS. YOU CAN EASILY CONFIRM THIS BY LOOKING OVER THE SIDE AND SEE WHERE THE CALM WATER OF THE SWING MEETS THE RIPPLES COMING OFF THE HULL. THIS IS THE PIVOT POINT. THE MASTERY OF PIVOT POINTS IS WHAT MAKES AN OUTSTANDING SHIPHANDLER. SEE ANOTHER VIDEO ON MY PHOTO & VID GALLERY TO SEE THE RIPPLES I AM TALKING ABOUT.

WHY SHIPS LOVE SMOOTH HANDS!

REMEMBER SHIPS AND BARGES OR ANY LARGE VESSELS CARRY WITH THEM A HUGE AMOUNT OF MOMENTUM. THIS MOMENTUM MUST BE PERSUADED, IN A NICE WAY, TO CHANGE DIRECTIONS AT YOUR COMMAND. IF YOU TRY TO FORCE A SHIP TO CHANGE DIRECTIONS WITH BRUTE FORCE, YOU WILL BE IN FOR A REAL SURPRISE. I SEE THIS A LOT WITH THE CRUISE SHIP CAPTAINS WHO DO THEIR OWN MANEUVERS. THEY TRY TO STEER THE SLOW FORWARD MOVING SHIP WITH THE BOW THRUSTER. THIS IS LIKE INSTEAD OF USING THE HANDLE OF A SHOVEL, YOU PICK UP THE DIRT BY THE SCOOP END. WHY TRY TO STEER A SHIP BY ITS PIVOT POINT. I COULD GIVE YOU MANY EXAMPLE OF GOING AGAINST THE FLOW OF MOMENTUM. THE MORE IN TUNE YOU ARE WITH THE FORCES THAT GOVERN YOUR VESSEL, THE MORE EFFORTLESS YOUR MANEUVER WILL BE, AND YOU WILL LOOK LIKE A DOCKING GURU DOING IT. SHIPS LIKE SMOOTH HANDS.
