What it means, why the same number gives different ranges at different ports, and how to plan with it.

The best times to fish with the tide
Why moving water fishes better, how to work the tide change, and what solunar theory says — and doesn't say.
Shellfishing and tides: when to head down at low tide
The low-tide window, why spring tides expose the best rocks, and which low-water height really matters.
How to read a tide table
Times, heights, the mystery of negative numbers, and why two serious sources can disagree and both be right.

Coves that close off as the tide rises, rip currents, and how to plan your swim with the tide on your side.
