Definitely Cullercoats / Tynemouth though; you never get seas like that in Fleetwood even on stormy day, way too shallow; hence the lack of sheltering piers in these parts, just pleasure piers, erstwhile or otherwise...
Little boats too; the once ubiquitous coble, as you can see in the Carmichael painting. Once a real feature of the NE coast, though you don't see so many of them now. In the words of the old Newcastle folk song:
There's Tynemouth and Cullercoats And North Shields for sculler-boats Westhoe lies iv a nuek; South Shield's the place for muck
Sculler-boats? No idea; racing sculls just don't fit with the area. I've heard it sung as shuggy-boats which I associate more with Tynemouth (and Cullercoats if I remember right) than North Shields (the town of my birth).
