NEGATIVE TRIM TRANSITION
AS THE TRIM ANGLE MOVES TO THE NEGATIVE POSITION
CREATING AN UPWARD THRUST ANGLE ON THE TRANSOM, HULL
PRESSURE IS MOVED FROM THE TRANSOM OF THE BOAT
TOWARD THE BOW.
HULL CONTACT PRESSURE BEGINS TO MOVE FORWARD OF THE
CENTER OF GRAVITY (CG).
AS THE PRESSURE MOVES FORWARD WITH CONTINUED
NEGATIVE TRIM, THE TURNING FULCRUM MOVES FORWARD OF
THE CG.

NEGATIVE TRIM EFFECT
CONTINUED NEGATIVE TRIM WILL ULTIMATELY MOVE THE
MAJORITY OF THE HULL CONTACT PRESSURE COMPLETELY
FORWARD OF STEPS.
HULL CONTACT PRESSURE IS NOW SIGNIFICANTLY FORWARD
OF THE CENTER OF GRAVITY (CG).
IN THE CASE OF A STEP BOTTOM BOAT, THE HULL OF THE
BOAT AFT OF THE CG NOW HAS LITTLE OR NO CONTACT
PRESSURE AND THE TURNING FULCRUM IS NOW
SIGNIFICANTLY FORWARD OF THE CG.
