Custom made clock that tells the tide and tidal streams for your local port and beach
Its mechanism and computer feature a complex calculation combining the lunar and 93 other harmonics.Therefore it is far more accurate than any other existing type of tide clock. The usual cumulative time deviations regularly add up to more than two hours. These revolutionary clocks reduce it to less than five minutes.

Jacob Venker's  tide clocks are always custom made. The hand of  these clocks  intersects the margin of the local polar tide plot, showing the water level, including the average slack moment of the local tidal stream.
