A mate of mine just built a solid deck for his 24'
cat. Vac bagged Polycore with 600 glass on top, 400 underneath.
Finished weight was 2.3 kgs per sq m. Strip planking does not need as much
fore and aft glass as non structural core, so the weight works out pretty
sim,ilar. The savings are on the vac bagging and areas where the
lengthwise strength is not required, such as bridgedeck and bunk bases, where we
used Nidaplast/600/400 (similar to Polycore). Vacuuming vs careful
hand laminating will be closer to 0.5 a kg per sq m than 1.5.
Mark may have some more exact numbers, but is up to
his neck in carbon poles for the next week or so.

Using vacuum bagging and polycore I was wondering how much
be saved for 'Rare Bird'. Is 1.2-1.5kg/m2 unreasonable?
