2.0– Hull Assembly
After unpacking the hulls, verifying the contents and verifying they did not receive any
damage in transport, find a flat level area to begin the assembly of your boat. Using
the foam end blocks set the hulls so they are parallel and approximately 84 1/2” apart
as measured from the centerline of each hull. The hulls of the F18 are canted outboard
3 degrees. Use a wedge on the base of the foam blocks to set the hulls so that they
are at this 3 degree canted position. To verify the placement of the hulls, use a bubble
level placed in the beam pocket of each hull. The pocket base will be level once the
hulls are adjusted to the proper degree of
cant. If you do not have the foam
shipping blocks, place the hulls on
carpet, foam blocks, or other smooth item
where they can be moved without
damaging the surface. You can use
towels or wedges to ensure that the hulls
are set parallel and at the same pitch
angle relative to each other.
With a tape measure first check the
width, then make sure that they are
positioned the same fore and aft, by
taking opposing diagonal measurements
from the same location on each hull. Note, that once the hulls are canted to the proper
3 degrees, the width measurement along the hull centerline will not be same along the
length due to the contour of the hull shape. It is important to try and start with the hulls
as close to the final position as possible. The beams have been prefit at the factory
and the beam sockets in the hulls have very little slop. If they are positioned correctly,
the beams will drop right in place, The forward beam pocket is much deeper and may
be snug. Note: on the rear beam, the tramp lacing buttons should be aligned to the aft
end. On the front beam the traveler track should be placed forward.

Once the hulls are set, remove the end
caps and the bolts from the cross bars and
set on the hulls. Dry fit the bolts to ensure
everything will fit smoothly. The hulls were
pre-assembled in the factory, so if they are
aligned properly, the bolts should slide
smoothly into the hulls. After you are
confident of the fit, lift the beams and place
