Next are the surface details on the hull. Here it’s mainly about weld lines and rivets.
A few comments about those details: On many boats one sees weld lines and rivets, often very prominent, too often way too big. Here it is often useful to think a bit about the scale o the boat. My Nautilus is built 1:87 scale (H0). I apply weld lines of 0.3 mm width, which would make them 2.6 cm wide on the original. That’s already quite big. Many rivets I had on model submarines would be as big as soccer balls, weld lines as wide as 10 cm. Sometimes less is more.
For the weld lines I use decals with resin relief, so called surface details from Archer Fine Transfers. What they are and how they are applied is demonstrated here:

The boat is put upside down onto the board and centered along the symmetry line:
A vertical marking board is built from spare wood. The board is positioned on the segment markings:
Now the weld line markings can be transferred onto the hull using a pencil:
Additional markings are laid down using masking tape and then transferred using a pencil:
The weld lines are 0.3 mm wide Archer Fine Transfer surface details:
First, the edge of the deck superstructure is emphasized:
