TURNING A STEP BOTTOM BOAT
“TRADITIONAL” TURNING TECHNIQUES ARE THE BASIS FOR
MOST INCIDENTS INVOLVING STEP BOTTOM BOATS.
TRADITIONAL V-BOTTOMS REQUIRE GREATER POSITIVE TRIM TO
ATTAIN TOP SPEEDS, AND TRADITIONALLY OPERATORS APPLY
NEGATIVE TRIM TO BRING THE BOAT BACK INTO CONTACT WITH
THE WATER PRIOR TO TURNING.
NEGATIVE TRIM WHILE TURNING A STEP BOTTOM BOAT CAN
CAUSE SEVERE AND VIOLENT SPIN-OUTS.
NEUTRAL TRIM
WHEN THE BOAT IS TRIMMED IN THE NEUTRAL POSITION,
PRESSURE, AND THEREFORE CONTACT, IS FOCUSED AROUND
THE CENTER OF GRAVITY AND TOWARD THE TRANSOM.
CONSISTANT HULL CONTACT IS MAINTAINED FROM THE
FORWARD STEP TO THE TRANSOM PROVIDING A STABLE
RUNNING PLATFORM.
THE TURNING FULCRUM WILL TYPICALLY BE LOCATED AROUND
THE HIGHEST AREA OF HULL CONTACT PRESSURE.
