Hello Dear Friends
I have finished the lower deck ...
After which I have given it a layer of shellac for protection. Honestly, I don't really see much of a difference - maybe the shellac has made it slightly darker and given it a slightly more "honey" color.

Bear in mind that the only two parts of this deck that will be visible, are the two hatches. The rear hatch can theoretically be viewed through the gratings of the rear canopy, but in reality, you see nothing. The front hatch will be visible, but only if I do not install the front deck grating. Once that is in place as it is on WB #1 there is nothing to be seen of this hatch either. Therefore, I have made absolutely no attempt whatsoever to incorporate and deck planking pattern, do caulking etc. In fact, I have used much longer strips, and I quite like the smooth uninterrupted look.

I installed the rear keel permanently and, as with the rest of the transom wiped, it with a tissue (non-fluffy kind) dabbed in shellac. Right at the bottom of the keel (where it rests on the table) you can see the two 1.5mm recesses that have been filed on either side to accommodate the garboard strake and the one immediately following it. In Dutch shipbuilding tradition, these two strakes run all the way through to the rearmost end of the keel. After the glue was dry, I drilled two 1mm holes through the keel and into the false keel and hammered two toothpicks into the holes to secure the keel permanently. Those two were then sawn-off flush with the keel and the whole keel sanded.
You can see that the keel has a very pronounced and heavy grain pattern that I don't quite understand. It is almost like the char from the laser-cutting, but no matter how much I sand, I can't really seem to subdue the effect. I don't know whether the laser-cutter is set to a higher temperature when cutting the oak, as it seems much more difficult to remove the char from these pieces than with the walnut. In any case, this will all be covered by the rudder (I just hope that the rudder is not the same), so I'm not too perturbed by it.
