: Mike and Bennie,

: again, all good points.... currently we use a standard canoe and it is o.k.
: stability is good enough as long as any moves are anticipated which isn't
: always the case with kids;^)

: I think this other boat would seem like a boston whaler in comparison.

: on the subject of constuction, the boat in the picture was built by a high
: school shop class according to the write-up... and from the looks of it,
: they used 6 or 8/4 stock? I wonder if I could use spruce lumber by
: selecting clear 2x6 lumber (framing lumber from lowes/Home depot?) to keep
: cost down.

: I'm in the southeast and priced some RWC yesterday. it runs about $5 a linier
: foot (1x8 stock).

: suggestions?

Hi Doug,
Spruce will certainly do for stripping a boat. It's a bit heavier than cedar but stronger, doesn't crush as easily, so you could make the strips thinner for the same strength. There is a limit on how thin you can go as the glass performs best when spaced farther apart. It's a function of the square of the difference.
It will give a lighter coloured hull, fairly white shading to a yellower colour over time and sun exposure.
The sanding dust is much less carcenoginec than cedar, but wear a good mask anyway, any timber dust is bad for lungs.

I don't know how $5 a linear foot for cedar compares with spruce, but if you can get clear spruce cheaper, go for it.

I think it smells nicer than cedar to work with.
