Settee Bunk Tops...

Settee top support framework


A straightedge helps align settee top supports

Access port covers are supported by rings that also stiffen the settee top.

Underside of settee top gets 2 coats of unthickened epoxy sealer.

Extension of floors...



To keep an open feeling inside the boat, the number of big bulkheads going all the way to the deck has been minimized.  Transverse foam-cored floors (shown in blue) and the spruce floor (in gold just aft of the keel trunk) provide the necessary support.  Each foam floor has a medium density core covered with 4 layers of glass cloth interspersed with 8 layers of carbon unidirectional reinforcement.  This essentially creates a box beam.  Each floor assembly is vacuum bagged which clamps the layers together and helps provide a good resin/reinforcement ratio.

The foam-cored floors are installed in two stages.  The illustration above shows the first stage with the floors installed over hull strakes #1 and #2.  Other structure goes over the floors at this point.  After hull strakes #3 and #4 are installed the 2 forward foam-cored floors are extended over these strakes.
