It Begins

We start tomorrow, Monday, building the cormorant fishing boat. Last week we built our shelter structure, a project started by one of the furniture students at the Gifu Academy of Forestry Science and Culture. He's going to be joining us on this project. Also working with me is Marc Bauer, a naval architect from California, whom I worked with on several projects with Tri-Coastal Marine.

And while mentioning links, Masashi, Kutsuwa, head of the furniture program at Gifu Academy, is posting photos here.

As mentioned in an earlier post last January, we will be building a cormorant fishing boat like this one, working with Mr. Seichi Nasu. 

Our framework, necessary for propping boat planking into shape, with its tarp roof, on site at Gifu Academy.

A new nail alongside some old nails. Nasu uses a unique nail called an umbrella nail (top). We ordered a local blacksmith to make us several hundred nails. The middle nail Nasu salvaged from an old boat, something he was forced to do when his blacksmith passed away.

Nasu soaks his nails in brine to get them rusted. He believes it gives them greater holding power.

We are all wearing hats I designed and produced with the characters for "cormorant boat" in Japanese, an item we'll be selling to raise some extra funds. This project is funded with a generous grant from the Freeman Foundation of Honolulu, Hawaii. We are currently negotiating with Tobunken and the Ministry of Cultural Affairs on a possible partnership on a publication (stay tuned), and we will hear soon about additional funding from the Asian Cultural Council of New York. We also received a generous donation from Mr. Georg Hinteregger of Hope Valley, Rhode Island.

Our workshop is right next to the furniture workshop. The new program started recently and students have been studying sharpening. Masashi has an interesting device to check the work.

He bought a 100-power magnifier for his iPhone camera and he photographs the tool edges to check for sharpness

Here is a local fishing boat Nasu san built. Boats in this region are sized by the length of the bottom (not uncommon in Japan) and this boat is about twenty feet (bottom) long.

Our first day off Marc and I went to Kyoto and at the end of the day stopped in to see Nagatsu Shoichi, a saw sharpener I have blogged about several times. His apprentice had just finished grinding gullets into some saw blades.

Nagatsu san sharpening an azebiki he gave me.

The waters of the Nagara River and its tributaries are incredibly clear, and we see sport fishermen all over the river. We have the hot summer approaching and this spot, about a half mile from the temple where we are staying, is going to be my swimming hole.

Now in Gifu, Japan

For the last month I have been working on a boat commissioned by the new Japanese garden at the Frederick Meijer Botanical Garden & Sculpture Park in Grand Rapids, MI. They had a restricted space for a boat so I chose a design of a river boat I had studied on the Hozu River in Kameoka, Japan. This type, called an ayubune, features a wide plank bow, like a pram, which gives the boat more volume for a given size. That construction was required on the Hozu, which has stretches of white water. The wide stem give the bow more buoyancy and resists burying navigating white water.

I built the boat using southern cypress from stock I bought years ago from a mill in Virginia. The bottom and side planks were all edge-nailed using hand forged nails made by blacksmith Jim Fecteau of Huntington, Vermont.

The wide bow also facilitates bending the side planks since the curve and twist is less severe. I did make one center mold which is not traditional to Japanese boatbuilders, but I wanted to ensure the two side planks stayed at the same angle, and it simply speeded the process along.

When I was in Kameoka researching these boats I had the opportunity to interview the last man who built them. His father had spent his life building boats and the son (my age) apprenticed with his father but spent most of his career building fiberglass boats. He told me the bow/bottom and transom/bottom connection was a tongue-and-groove joint. I mimicked what he described, but used a spline instead of a tenon. I routed a groove in the edges being joined and then inserted a spline when I assembled them. It was easier to make the joint more precise this way and I could gain some strength by having control over the grain direction in the spline.

The decks fore and aft are let into the side planks and the beams fasten with a half lap dovetail joint. There is one floor timber that is connected to the beam with a vertical plank. I made a twelve foot sculling paddle which can also be used like a pole. On the Hozu most small boats like this one were poled with bamboo push poles.

In Kameoka I was able to measure historic ayubune in 15, 18, and 24-foot lengths. If I teach my Winter Term course in Japanese boatbuilding at Middlebury College again next year my plan is to build the largest version with students.

I dropped the boat off Saturday at Adirondack Guide Boat in North Ferrisburgh, Vermont for shipping to the customer. I am writing this post on the plane to Japan. As I mentioned in a blog post last January, I am going to be building a cormorant fishing boat in Gifu, Japan with Seichi Nasu, an 85-year old boatbuilder. This project has been years in the organizing and fundraising, so stay tuned for regular posts chronicling the construction of this very unique boat.
