>I tried steaming bamboo, I used the whole stem, this was no good. Bamboo does not have so much mass, it holds the heat for a mere 8 to 10 seconds. So it bends and then splits. That it was Februari and freezing outside in an unheated shed did not help either. A trick I found later was to use insulation for copper waterpipe. This will keep the heat in. Bending bamboo strips this way is no problem. You need a seizing at the ends because it will split. Splitting is structurally not a problem for bamboo, because of its longitudinal fibers. Don't drill holes in it, lash everything.

Anyway, for my little boat a strip of 3 x 12 mm. proved to be plenty strong. 3 x 12 mm. is something like 2/16 inch x 1/2 inch. Sorry I am not familiar with feet and inches.

Robert Morris - Building skin-on-frameboats - and Skip Snaith - Umiak, An Illustrated Guide - proved to be invaluable. Dacron is not available as such in the Netherlands. I made do with reinforced plastic.

If you are in Amsterdam I would be happy to show you my boat and the place where it is built:
http://botenloods.nl/ where someone has a Klepper too.

As discussed on Qajaqusa (http://www.qajaqusa.org/cgi-bin/GreenlandTechniqueForum_config.pl?page=7;read=167237):

: it's edge laminated 6mm carbonized bamboo 4x8 paneling sheets, costs 90 bucks
: a sheet, available from nwbamboo.com, I steam it for 15-20 min.
I believe a slight clarification might be needed. It is indeed edge laminated but it is also vertical grained and not flat grained. Both styles are available. It is also single layer and not a multi-layer laminate.
It is good stuff and I have used it on 2 kayaks, just bear in mind the steam time.
-- end of posting --
I have not spend any time trying to source it here on the East Coast, but will try now.
