Basic layup hull panels
Outer laminate 2 layers 600/150
linrovmat (Ist layer vertical, 2nd layer
horizontal), all joints to be
butted, no overlaps, matlayer down first.
Core 12 mm PVC foam
(Type 75) or similar.
Inner laminate 1 layer 600/300 g Duomat, mat
layer down first.
Keel joint as for the solid glass boat, but
extend final csm layer up to the
waterline (not applicable if vacuum
bagged panels are used.).
Note: hull panels should be glassed on both
sides (and filled and sanded as
appropriate) before offering up to
bulkheads. Stringers on hullskin are not
necessary, however, the number
of bulkheads should not be reduced and interior
fittings (shelves etc.)
should be as the standard boat.
Basic layup decks
I Layer
600/300 Duomat on each side of l2 mm PVC foam. Flat panels should
be
glassed, filled and sanded on both sides before offering up to boat,
cambered
decks should be glassed on inside only before offering up.
Deck stringers and
frames are not required (but temporary supports will
be necessary). Insert ply
pads under all deck fittings. All corners
should be rounded off to a min. 12 mm
radius and glass joints made as
for standard hull/bhd joints.
It is recommended that bulkheads and
interior frames and partitions be made in
plywood to save unnecessary
finishing.
Beamboxes should be in plywood, as on wood decked boat.
Centreboard box can
be foam sandwich, with laminate as for decks.
Adjust bulkhead cutouts, knees etc.
for extra box
thickness.
