Rick,
After you are done glassing the hull, what do you think the final thickness will be? Will it be thicker below the waterline or same throughout?
Hi J&T
It's a wee bit thicker on the bottom where I used a 33 oz triaxial fiberglass plus the 12 oz.
Working from the inside out on the bottom & assuming a 50/50 glass to resin mix it'd be something like:
10 oz cloth is .017"
12 oz 0/90 is about 0.023"
1708 is 0.029"
1/2" Meranti BS1088 plywood
33 oz triax wetted out is about 0.050"
12 oz 0/90 wetted out is about 0.023"
So total would be somewhere around 0.142" which is something like 9/64". Including the 1/2" core that's a total of 21/32" or 0.640"
The sides are double the inside bottom plus 1/2" core so that's about 0.059" a little over 9/16" thick.
I haven't cut any holes in the hull yet but I'll be able to measure it then.
Doesn't sound like much does it?
The bow area and keel bottom also have an extra layer of multiaxial carbon fiber (Saertex) which I think was 22 oz/yd and probably about 0.035" thick
The transom has 20 oz basalt fabric, 1708 and 9 oz satin weave outside. It has a 1" core and inside will get 1708 plus 12 oz 0/90 and 10 oz plain weave.
All of the seams have at least 4 layers of 6 oz tape plus double the fabric overlapped. I wouldn't even venture a guess how thick they are!
