When lofting the side panels, use the regular lofting numbers for
the bow and stern ends to get the correct bow and stern stem angles.
Mark
the bow and stern stem angles now. Do not use any adjusted lofting
numbers to get the stem angles.
Reduce the
height of the entire
sheer
line
on the side panels by the amount that you want the deck lowered.
Note that the Point Bennett side panels are lofted upside down.
As a result,
to reduce the sheer line height you need to add the amount
you want the deck lowered to all the sheer line lofting
numbers. For example, one of the lofting points for the Point Bennett
17.5 says, "At 7 feet to the right the sheer is up 1 1/2 inches
and the chine is up 8 15/16 inches." If you were lowering the deck
by
2 inches, you would add 2 inches to the sheer number, which in
this case is 1 1/2 inches. Your adjusted sheer number would be
3 1/2 inches.
Complete the assembly of the hull, including fiberglassing
the outside and inside. With the hull complete, make sure the
sheer line is fair. If it is not, use tape to bring in the bulges
and insert boards to widen the hollows.
Loft and cut the deck
like normal. Before the peak in the deck is formed, lay the flat
deck on the hull, and center the deck on
the
hull both
lengthwise
and widthwise. Use a pencil to trace the outside of the hull sheer
line on the underside of the deck. Remove the deck and flip it
over. Make sure the pencil line is fair and that each side is
an equal distance from the centerline of the deck. Mark another
line 5/32 of an inch inside the pencil line to compensate
for the 4 mm width of the hull panels. Trim
the
deck
down to this line.
Continue building as normal, except that you will have to reduce
the height of the deck peak at the front of the cockpit by the same
amount that you reduced the height of the sheer line.
