Thanks for the comments.
Baillien is indeed surviving and I must admit, with the webshop they have, I'm kind of ordering more as well. While I would get stuck on projects due to a shortage of some material and collecting larger orders to travel there once a year (or 2), now I'm simply ordering it and I throw in things I don't really need to get free shipping
The webshop isn't entirely easy to work with, but it's fine. They do have a huge stock of materials, which does make for a very fast delivery.
Continuing on various areas. The seabed has now received the sand. I used extremely fine sand from children's sandboxes. The circle around the windmill will be filled with a more coarse grain, since those are rocks in reality.
You can also see the monopile (brown thing) that is first put in the seabed and the transition piece (which is the yellow thing sticking out above the surface). The transition piece will also be cut so the whole pile serves as a support for the plexi plate.
The sand is actually a mixture of water, heavy acrylic gel and sand. Dries pretty hard and seems to stick better than sanding paper. I could shape the seabed with more of this mixture if I need to, but I'm ok with it for the time being.
The ship itself I'm preparing for the light green coat, currently adding the "bulwark" plating around the vessel. Crane and excavator pedestal are also in progress, but will be painted separately and are just dry fitted for now.
I know the vivak plates on the sides are cracked, this happened during the cutting process. Lesson learned: don't cut it like plexi glass. If you just scribe it and try to snap it, it'll crack... No matter how deep the initial cut was. The only way to do it properly seems to be cutting it first and then go through it with a small sanding disc. I'll redo the cracked sides.
