How Gosport Harbor, Isles of Shoals fishes

Open water lies to the east of Gosport Harbor, Isles of Shoals. A wind out of the east is onshore here — it stacks swell and chop into the mouth and pushes stirred-up water inshore, while a west wind flattens the surface and tends to clean it up.

Tide is the clock: moving water pulls bait through the mouth, and the turns around slack are when most of the roster feeds hardest.

Tides here are read from NOAA station 8427031 at 42.9783, -70.6150 — see it on NOAA CO-OPS.
