My Locations / Boats
To find out when your boat starts to float or dry out, enter your boat name and height above chart datum and click on the plus sign. Similarly, this can be done for other specific locations by entering the location name and height above chart datum and clicking on the plus sign. You may have up to ten locations. The first location will appear in the tides area on the right hand side of each website page.
Please enter your boat name / rock name / location and their respective Height (M) above chart datum *
	Here are two examples. 1. Gorey Harbour The pier at Gorey dries at 4.0m ABOVE chart datum. Therefore at a tide height of 4.0m the harbour will just be awash. A vessel of 1.0m draft wishing to navigate safely with no less than 0.5m under keel clearance (UKC) should add 1.5m to a drying height to calculate the time to safely enter the harbour. Therefore enter 4 + 1.5 = 5.5 to calculate the earliest or latest safe time. 2. Castle Breakwater End passage approaching St Helier The nearest danger to this track is a rock that is awash just west of the breakwater end. Awash means the rock is at chart datum, or zero height. Therefore the same boat drawing 1.0m and requiring 0.5m UKC should not enter this passage until there is at least 1.5m of tide. To ensure safe under keel clearance, mariners should also take into account any variable conditions that could affect the calculation (e.g. swell, wind, waves, atmospheric pressure etc.)
