THE “TRUE” BOTTOM OF A STEP
BOTTOM BOAT IS THE IMAGINARY
SURFACE CREATED BY RUNNING A
LINE FROM THE FORWARD STEP TO
THE TRANSOM AT THE KEEL.
STEPS EFFECTIVELY “LOWER” THE
TRANSOM THEREBY CHANGING THE
NATURAL ANGLE OF ATTACK.
STEP BOTTOM BOATS RUN BEST IN A
NEUTRAL TRIM POSITION DUE TO THE
NATURAL ANGLE OF ATTACK AND THE
REDUCED SUFRACE ADHESION
CREATED BY THE STEPS.

STEP-BOTTOM TECHNOLOGY
A V-BOTTOM BOAT RUNS MAXIMUM SPEEDS WITH MINIMAL HULL CONTACT. HULL
CONTACT WITH WATER CREATES ADHESION.
A TRADITIONAL V-BOTTOM BOAT REQUIRES A GREAT DEAL OF POSITIVE TRIM TO
AFFECT A MODERATE RELEASE OF HULL CONTACT WITH THE WATER.
POSITIVE TRIM USES HORSEPOWER TO CARRY THE BOW OF THE BOAT AT THE
PROPER ANGLE OF ATTACK, AS WELL AS PROPEL IT THROUGH THE WATER.
A TRADITIONAL V-BOTTOM RUNNING AT MAXIMUM SPEEDS HAS VERY LITTLE HULL
CONTACT FORWARD OF THE BALANCE POINT, THEREFORE IN ORDER TO TURN THE
BOAT, IT MUST BE SET BACK INTO THE WATER, USUALLY BY MOVING THE TRIM
INTO A NEGATIVE POSITION.
