Has anyone used the Shou Sugi Ban technique to treat the exterior or interior of their wooden boat? Looking for advice on how to pull something like this off. I am open to being called crazy too!

Is it a deliberate charring for preservation, or just a by product of using heat to bend planks when it appears in boatbuilding? I think that boat soup with wood tar would be better, as it will get more tar into the wood.

This has painted decoration, but no charring.

Thanks for your thoughts. The charring is mostly for aesthetic reasons, secondarily for preservation. Nice photo! I love those giant Ayubune of the Hozu River. Do you build these boats? How fun would it be to take that down the Colorado River! I wonder if the Shou Sugi ban would crack off as the planks were bent in place? Or maybe just char after the boat is built… hmm, shrinkage? damage to the copper/bronze fasteners or glue? Potential for disaster but would be so pretty if it worked.

I took that photo at Brest at the 2004 IFOS. The first time Japan had attended.
Using heat with charring to bend the plank only burns one side, and the edges have to be cleaned up as the boat is assembled. I have seen a boat that had a fire inside, there was little sign of burning on the outside even though all of the inside was charred. Except where the fire had tracked through the seams, creating small localised gaps just visible from outside. I suppose that If you had plank stock thicker than the design called for, you could build a dory or skiff out of charred plank. You would need to clean up the edges though.
