Construction Details

The first was built by Shaw Boats in Aberdeen, WA.  The second was built by Barry Smith in Seattle WA.


The goal of the construction was to maximize performance for a given cost and maximize the use of laminated flat stock.


Hull below the chine was built of strip planked Duracore with eglass/epoxy skins.  The sides were built from eglass/epoxy skins on cross linked PVC core layed up on a flat table and cut to computer patterns.  These sides weighed 32 kg each and were sprung into the female building jig.


The deck and cockpit were similarily built from carbon/foam flat panels and the house was carbon skins over a strip planked foam core.


All interior panels are built from lightweight composite panels cut out to accurate computer patterns for minimum weight and minimum waste.


The spar was built by Hall Spars and rigged by Paul Bieker in Seattle.  Standing rigging is discontinuous rod.
