Glassing the Inside
|
This photo shows "wet" glass covering the entire interior
of the boat, with dry glass hanging over the edges. I did not
use mat on the inside surface because I wanted to see if it added
anything. It seems that all it adds is weight and (mostly unreinforced)
resin, although the inside is definitely less puncture-resistant
than the outside. Production boatbuilders use mat between layers
of woven roving as a form of cheap core material, but it seems
unnecessary for this type of construction. When I do it again
I'll just use a slightly heavier glass and eliminate the mat
altogether. I think 9-12 oz. glass on the outside skin and 9-oz
glass on the inside would be as strong, and lighter, than glass
plus mat. |

Once the interior starts to gel the extra glass can be trimmed
around the sheer. |
