Field notes
The homepage separates broad shallow-water coverage from sharper named-area maps and says every detailed map carries its typical error. Its tools are described as point-depth readings in metres or feet, draft checks, and route planning; a score for each hour of the week uses wind, waves, tide, and daylight. Separate sections cover shoreline measurements since 2017 and fish guidance based on depth, bottom, water conditions, season, and tide.
