I thought that surface area makes for more building time, ie. but suface area should be prportiopnal to weight. I mean a twice the length boat is taking 2 cubed which is 8 times longer?

Settling on a core materila feels alot like getting married where you think about it until the day it happens and then you think about it no more.

Although I have a lead on foam for 1/2 the boat I am stillplaying around with using balsa and honeycomb. I don't need to make this final decision for a while. Until then I'll make some test coupons and play around with the different materials.

Seems like there's four categories for determining core.

1. Cost (like honeycomb)
2. Weight (like foam)
3. Structural Characteristics (foam/balsa)
4. Preference to work with (balsa)

We'll see which shakes out at the end.

Have you considered polypropylene honeycomb as a core? Rob seems pretty happy with it
