Tidal Flow Legend

▶

Green cones — Flood tide direction (330° NNW). Cone points the way water flows during incoming tide.

▶

Red cones — Ebb tide direction (150° SSE). Cone points the way water flows during outgoing tide.

Red surface — High current exposure. Structure face catches tidal flow head-on. Bait concentrates here.

Dark/neutral — Structure runs parallel to flow. Moderate current interaction.

Blue surface — Sheltered lee side. Eddy zone — fish hold here out of current.

Tidal axis: SNE Shelf standard. Exposure reverses between flood & ebb — toggle each to compare.
