From the description, it sounds like a "standard" extended logboat, i.e., a basic dugout hull, with the sides made higher by the addition of a strake.Bob Holtzmanhttps://www.blogger.com/profile/05878339327766256094noreply@blogger.comtag:blogger.com,1999:blog-6466695305125791022.post-66020568885092354732014-07-09T12:17:51.877-07:002014-07-09T12:17:51.877-07:00Would you describe this logboat (based on its desc...Would you describe this logboat (based on its description) as a hybrid between a traditional Neolithic logboat and a Sewn-Plank boat.

I can't recall any logboat though that has suffered damage in this way although same have sewn patches that might indicate collision damage.<br /><br />Most logboats are not found in rocky areas, mud being the preserver. However, I wonder if a rib helps to stiffen against bending both laterally and longitudinally when the prow is run up on a bank.<br /><br />Another item from that article is the boat held together with the"Ferriby" technique of transverse rods. I believe this is the first confirmation that this building method was used elsewhere than England and might indicate that it was quite widespread and such boats common.<br />Edwin deadynoreply@blogger.comtag:blogger.com,1999:blog-6466695305125791022.post-56876204952415979252014-07-02T06:42:01.694-07:002014-07-02T06:42:01.694-07:00Edwin.

It seems that the longitudinal member would strengthen the hull against forces in the hogging direction, comparable to "oil canning" in a plastic canoe.Bob Holtzmanhttps://www.blogger.com/profile/05878339327766256094noreply@blogger.comtag:blogger.com,1999:blog-6466695305125791022.post-17902768759080026102014-07-02T06:26:47.087-07:002014-07-02T06:26:47.087-07:00It is claimed that carved ribs in a logboat do not...It is claimed that carved ribs in a logboat do not add to its strength as the grain in the rib is the same as in the body of the boat thus a split in the hull is likely to carry on through the rib as well. It is possible that some of these ribs were to brace the feet against when rowing.<br />Edwin deadynoreply@blogger.com
