No updates for a while on the bulding, but we have not been idle. Tonight we finished glassing the hull half, and glued some parts of the bulkheads together.
We put on the glass at +-45deg to the planks. It does mean that we have an overlap on the glass between sheets, but it should give more strength and stiffness. Pretty interesting stuff, just hope the sanding will not be too bad.
Also a boon to be able to put on the glass in several small operations instead of one large. I hope to have time for layer two of epoxy tomorrow night, and then it comes off on wednesday for inside sanding and glassing. Perhaps we are able to put the hull on some scales and get a rough weight estimate. Inquiring minds all over the catsailing world wants to know..
5mm strips glued together to form the basis for bulkheads. We will use a router later on to shape them to their respetive stations in the hull. Should be a really lightweight replacement for full plywood bulkheads.

Hi Rolf,
Do you have estimate about how long will it take to strip plank a hull? Just wondering how it relates to torturing time wise.
Valtteri,
I have no doubt that building in ply is much, much, faster. I dont have the hours yet, but cutting strips, fitting them togheter on the mould, gluing, sanding, glassing, turning over, sanding and glassing got to be way slower than torturing ply. If you count the building sessions on the blog, you should get a rough estimate for the first hull half. We expect the time to drop considerably as we get more experience at what we are doing. The glassing went really quick as that was familiar terrain, so stripping should also be quicker from now on.
If you watch the blog, you can try counting sessions for the next half. Each session lasts from about 1915 to 2200 hours.
Good to see your progress guys! Would not a uni glass 90° to the wood fibers be sufficient as the Norwegian timber has a lot of strength itself? And perhaps lighter? And no overlaps needed, just put the fabric edge to edge. Just a thought...
If you put fibers 90 deg to the wood you can still twist the wood easily, but putted 45 ded that will be more difficult.
