Good morning Jan. Hull fairing is something I am very nervous about. Especially if the bulkheads are soft wood as I may change the symmetry. I do agree with Paul tho. If I look at the last stern bulkhead it would seem that the planks would just touch the outer end of the bulkhead (May be photo angle which creates this perspective). Cheers GrantYes and no, That is a bit of a tricky area and needs a bit more work. My major problem was in the bow. The starter plank was OK but the next set of planks would not fit flush and bow out. Sort of a clinker effect. My other mistake was using a short sanding block (about 4 inches long) to do the fairing. Since then I've acquired three different sanding blocks (1 and 2 inches wide and 8 inches long).

I also use Heinrich's approved coarse sandpaper method.
