Steve - Randy's Tortuga is ready to launch - he is planning on returming to the SF Bay on 5/5 or so. Boy was it hot -- I was ready for some overcast on Sunday - Randy's boat was moved to a corner for bottom painting and there wasn't much wind!! Say Hi to Carmen from all of us.
I believe that the foam material used is below - I'll confirm with Dave King when he returns home.
H80 Divinycell Plain, 5lb./cu.ft., 48" X 85.6" rigid PVC (Polyvinyl Chloride) structural foam used in sandwich core construction. New formulation with higher physical properties and smaller cell structure.
He estimated that the boats with fiberglass gudgeons would need ~4 - 1/2" x 2'x4' sheets per boat - you could get thinner 1/4" sheets for use as the taper moves forward.
Boats with SS gudgeons would need ~6 - 1/4" X 2' X 4' sheets
The foam is single coated with 9oz glass cloth - woven.
For the 4 boats 2 - 5 Gal of West Systems epoxy were on hand - 1 was empty by 4/22 with 2 boats to go. The epoxy was also used on hull's gel coat, washed with water then the barrier coats applied. If you are only doing the aft fairing then you will NOT need as much epoxy. The hardner used for the fairing and hull repairs was 205/206 depending on air temperature. Bowsprit and boomkin first coat of epoxy used 207 a clear hardner.
If you have done auto body work with long sanding boards, have a low speed 8" disk sander, you have the major tools and skills. Now add in a little "artistic elbow grease" and time and this is a doable project.
All the boats received alot more work the just the hull fairing - makiing it hard to estimate the actual time for just the fairing work.
Hope this helps
Jay..
