Cruising British Isles & Channel
Few cruising grounds are as tide-driven as the English Channel and the waters around the British Isles. Spring rates over 5 knots through the races off Portland and Alderney, drying harbours that need the height of tide to enter, and one of the busiest shipping lanes on earth — this is water where tidal data and accurate navaids are not optional. The region covers the UK, Ireland, the Channel from Brittany to Calais, and the North Sea approaches.

Questions
Does the chart include tidal data for the Channel?
Yes — tidal heights and depth-aware routing are bundled, which matters where Channel spring rates exceed 5 knots and many harbours dry.
Does it cover Ireland and Scotland too?
Yes — the whole British Isles including Ireland, the Hebrides and the North Sea approaches, plus the French Channel coast from Brittany to Calais.
How good is the offline coverage?
