Double layer hull strips

Wanting to build a sailing ship wooden model. looking at a double layer strip hull. I have watched a couple of videos. my question is: After the first layer installed with glue and pins, do you sand the heads off the pins before glueing on the second layer?

I might be totally wrong but I would remove the pins.
If the cured/hardened/dried glue doesn’t hold the strips in place then
headless pins will not be able to do it either.
Sanding the heads flush sounds like a recipe for sanding too much off the strips.
I would use this type of pin:
drawing pin, push pin …
Unless the strips are too narrow so that pushing in the pin will split them.
Drilling a hole with a slightly smaller diameter than the pin would solve that problem, I hope …

The pins do have heads.

Remove the pins

Tell you the truth, the wood used in planking on many kits, especially foreign kits, is of very poor quality. If you have a hobby table saw it is better to cut your own wood and do a single layer. If not, don’t push the nails all the way in to where the head touches the planks. After the glue cures, remove the nails, sand/fill the hull till you have a smooth surface, then lay the 2nd layer.
