Not a great deal of difference.$83 for a 1200x2400x10mm sheet with
the top quality scrim suitable for vacuum bagging. Slightly cheaper
than Kiri at 1.20 a lineal m 40mm wide of the order of 25 - 30% for
core, based on the web available prices I could find. You need extra
glass, probably a little extra resin for the scrim, compared with how
much the timber soaks up, but less bogging and glueing. By the time
you include all the resin and glass the total savings are probably
about 10$ for the hulls. Maybe a little more by the time you include
fairing and sanding.
Jim Baltaxe would love to be able to start building, and there are a
few NZers already involved, Rob and Bain for a start.
It gets me that the price of NZ grown timber seems to be cheaper in
Australia. Don't know if the reciprocal works for Kiri.
Seems to me you're getting serious about building. May be worth
checking out the KSSboat yahoo group as a start for tips on using
synthetic cores.
regards,
Robert
