Construction Details

Built by Shaw Boats in Aberdeen, 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 carbon/eglass/epoxy skins on balsa core layed up on a flat table and cut to computer patterns.  These sides were sprung into the female building jig.


The deck and cockpit surfaces were similarly built from carbon skin /honeycomb core flat panels sprung into place like a “stitch and glue” dinghy.


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


The spar was built by Hall Spars.  Standing rigging is discontinuous rod.
