STEP 7(a): HULL PAD ALIGNMENT (V
-
HULL ONLY)
Before installing the hull pads, it is important to determine the bunk spacing: how far apart the hull pads should be
mounted on the cross beams. To calculate the proper spacing, refer to the table below. Consult your boat manufactur-
er for dead rise information.
How to Use the Bunk Value Table
The left section of chart shows pad separation and max dead rise angle to maintain
1”
minimum clearance to the
cross channel listed top to bottom. The right section lists dead rise angles (in 5 degree increments) from left to right.
The columns list the clearance values for the pad separation at the far left of the chart. Pad separation is measured
from the inside of the hull pads.
Aligning the Hull Pads
Place the hull pads as wide as possible while maintaining clearance between the hull and I
-
beam. Be sure to check
the boat, boat trailer, or consult the boat manufacturer to ensure the location is clear of underwater obstructions,
such as speedometer sensors, water pickups, fins, etc. The hull pads can be placed on the lift so that the front is nar-
rower than the rear if needed. If you do this, verify that the hull pad does not cross a stake or other feature on the
hull that would result in a concentrated loading condition. The chart below is based on the dead rise angle and sep-
aration distance and is provided as a starting point only.
