Ah I think I understand now. Several sections of the perimeter was dark grey still instead of black as you indicated, I just hadn't noticed it until zooming in really close lol. Take a look at this one, if it's better I'll go ahead and remove the others!
It does indeed look nice, literally the only thing I'd change is "Harbinger"!"Harbringer" (Me, grammar Nazi? Surely not!) - apart from that (in my limited experience) it looks like a great little boat!
A 25m Mk VI Patrol Boat I've been working on.

First drawing, the original was much cleaner but shrinking it down to scale size affected it quite a bit. Not a fan of sea shepards, but it's a beautiful design!
