There was just one thing left to do on the hull: the draft markings. The Balder only has these at the front.
When in the water, only 2 markings are visible above and below the waterline:

But fortunately, a volunteer still had a photo of when she was taken out of the water for inspection the last time. So, 4 markings below the waterline.
Get to work with thinly cut tape:

Yak ......But that is much too coarse.
Using a new scalpel blade that I sharpened on a strop, I cut it as thin as possible:

The white one is the old thickness, the blackened one is the new one.
With this as the result:

Mmmmmm ....... Slightly more acceptable, but still too coarse in my opinion. From a distance it's still okay, but with grazing light and macro ......
Started drawing in Photoshop and grabbed the sheet for waterslide decals. That required some serious thinking and reasoning about what was going wrong.
Because the white ink didn't transfer to the transparent versions. A quick test with a black frame and white letters showed that the white letters were masked out in the black.
So, in 2 steps:
-the black letter above the waterline on transparent decal.
-the white letters with a black frame on white decal.

The result after cutting and pasting. The decal is a slightly different black than the hull, and from a certain angle, a glare is also visible. Once it is completely dry, I will touch up the black paint on the hull a bit.
