No calculations; no need to adjust for summer time; all times shown as AM or PM (not the 24-hour clock); two years – what could be simpler? All UK, Ireland, and Belgium to Gibraltar – all with local summer and winter time – all based on official British tidal information. Since 1999 still £7.99 for each of QuickTide’s slim, colourful, four‐page, A5‐size cards.
