The first grinding was made with an excentergrinder connected to a vacumbuster that can endure continuous operation. It can otherwise cause a burnt vacumbuster. The next step is fairing the hull with a bendable board with grinding paper glued to it.
Now the boat looks like a speckled whale with all the putty and grinded surface. I asked Hasse if I could make the boat black but he recommended that I use bright colour to avoid too much heat absorbing in the sun that could cause print through i.e. you will see every glue line in the boat as the epoxy and wood behaves differently when heated.
