GENERALLY SPEAKING, A HIGHER X-
DIMENSION, UP TO A REASONABLE
LIMIT, REPRESENTS INCREASED TOP
END PERFORMANCE BY REDUCING
HYDRODYNAMIC DRAG CREATED BY
THE SUBMERGED GEAR CASE.
THE TRADE-OFF IS THAT WITH A
HIGHER X-DIMENSION COMES POOR
LOW SPEED PERFORMANCE CREATED
BY AIRIATION OF THE PROPELLER.
A NOTCHED TRANSOM HAS THE SAME
EFFECT AS A “STAND-OFF BOX” WHICH
ALLOWS A HIGHER X-DIMENSION
WHILE MAINTAINING NON-AIRIATED
WATER FLOW TO THE STERNDRIVES
AT LOWER OPERATIONAL SPEEDS.
AS THE BOAT MOVES FORWARD, THE DISPLACEMENT OF THE HULL CAUSES WATER
TO FLOW BACK AND UP FROM THE TRANSOM OVER THE STERNDRIVES. AS THE
BOAT SPEED INCREASES, THE UPWARD ANGLE OF THIS WATER FLOW DECREASES
AS THE BOAT PLANES OFF, APPROACHING ZERO DEFLECTION (NO UPWARD
TRAVEL).
THE NOTCHED TRANSOM HAS INCREASED WATER FLOW OVER THE STERNDRIVES
AT LOWER SPEEDS THAN THE TRADITIONAL TRANSOM, THEREBY INCREASING
PROPELLER EFFICENCY, ESPECIALLY IN HIGH X-DIMENSION APPLICATIONS.
THE INCREASED EFFICENCY RESULTS IN FASTER TIME ON PLANE, LITTLE OR NO
PROPELLER CAVITATION AT LOW SPEEDS, AND INCREASED THROTTLE RESPONSE.
