[Alberg30] deck core

[George Dinwiddie]

When I did the cockpit sole, I bought klegecell the same thickness
as the balsa.  Unfortunately, I also put a layer of glass mat down
first, causing the cockpit to have a gutter around the edge.  Now
I typically use thickened resin to bed the foam, and it doesn't add
to the thickness appreciably.

As for the choice of material, it's not going to matter much in small
areas.  In large areas, plywood might get to be heavy.  I chose
foam because it has the lightness of balsa but is totally rot-proof.
To be honest, I don't yet trust my ability to make FRP totally
watertight.  Also, foam is a lot easier to cut-to-fit than plywood.
I just used a mat knife.
