*Update 2*Bad news, yesterdag a worker from a wharf museum in Utrecht came by to messure the thickness of the hull (below the waterline) with a special tool.
It was not as good as I hoped, there are some small holes and many spots which are quite thin. So the hull needs to be dubbled, its welding new steel plates to the bottom on top of the old. But this is very specific work and takes alot of time, money and willpower. And I cannot weld..
So it is going to take a bit longer to prepare the boat for its plunge...
However I will now have plenty of time to take care of the engine and the rest of the boat. I now have to come up with a plan to restore the hull.
I will place some new photo's from the lister and the hull very soon. Its currently laying outside so I have better light and room to shoot nice photo's.
