Boatbuilder Douglas Brooks, who you should know all about if you follow this blog, has been teaching Japanese boatbuilding techniques in his classes at Middlebury College in Vermont.
This article appeared recently in Mainichi Shimbun, one of Japan’s three largest newspapers. I can’t easily read much Japanese, but this article mentions the pool launching of the Hozugawa Ayubune that the class built.
This is the same type of boat I recently modeled, based on information I got from Mr. Brooks. The boat shown here that his students built was a 6.5 meter boat, or a little over 21 shaku. My model, in comparison, is about 4.5 meters, or 15 shaku.
The class at Middlebury College actually built two boats during the semester. In addition to the Ayubune, they built a rice field boat, or tabune, from Niigata prefecture.
