Boat scrubbing tide calendar for the UK
Find the best tide windows to scrub your boat in minutes. BoatScrubCalendar combines UK Admiralty tide predictions with a simple monthly planner that highlights mornings when high water falls between 06:30 and 09:00, the classic window for drying out on a scrubbing grid or posts.
How the scrubbing day planner works
- Monthly tide calendar. High and low water times and heights for every day of the month at your home port.
- Scrubbing day finder. Days with a morning high water inside your preferred window are flagged, so you can float on, dry out and scrub before the afternoon flood.
- Official data plus harmonic predictions. The next 7 days use official UK Hydrographic Office tidal events; later dates use M2/S2 harmonic estimates, with year-long Admiralty data for subscribers.
- Club booking and reminders. Sailing clubs can publish scrub windows and manage bookings; members get maintenance reminders by email.

Frequently asked questions
What is the best tide for scrubbing a boat?
Most owners want a high water around 06:30 to 09:00 so the boat can be put on the grid or posts at the top of the tide, dry out through the morning ebb and be scrubbed and antifouled before the flood returns in the afternoon. Spring tides give more time and a bigger drop.
Is the tide data official?
The first 7 days come directly from the UK Hydrographic Office Admiralty Tidal API. Beyond that the calendar shows harmonic estimates, clearly marked as approximate. Subscribers get official Admiralty predictions for the whole year.
