Hi Darren,
If you are going to race it on flatwater go for one layer as it is lighter.
If you will be going in the surf you want a little more protection on the bottom at least; glue two strips together and then bead and cove them as one. Use them only on the bottom. As soon as you start to go up the sides revert to thinner ones. There is a danger with thinner wood of the kayak kinking in the length in waves (oil canning).

: Hi,
: Thanks for the input guys.

: I am leaning towards one layer, very carefully sanded, rather than two. Just
: a thought. I had thought snading the inner layer would allow the outer
: ones to conform to the shape, but then the outer ones would be flat on the
: inside so not lay down exactly - different from a larger boat where the
: curves aren't as great.

: So, one again I bow to the wisdom of experts (i.e. anyone but me, who has
: actually done this before). If the NH works, then I'll have strips left
: over for the micro bootlegger. But will be doing a racing K1 before that.

: Thanks!
