Reason for feature in Longcase clock

I am trying to find out the reason for the feature of 'high Water times' indicated together with the phases of the moon and date on a longcase clock made by Joseph Neighbour In the UK in I think 1800 and something. Any info on the reason or the clock much appreciated A related question What is the regular tide height at Bristol or Avonmouth

Sailing ships prefer to enter or leave port on a 'slack tide' where there is no current going either direction or (for some ports) leave as the tide is running out. It's easier to steer when there is no current shoving the boat around.

A clock that showed the tides for an area would be a great convenience in an inn or other building asssociated with shipping, because the time of high tide varies from harbour to harbour, day to day.

Good question ... I checked my American Practical Navigator and it said to look at the navigational chart for a harbour to get the tide highs and lows. Tried online and the UK Coast Guard site is not responding.

arrgh ... I was searching on 'tide charts'

High Tide 33.50 ft 1:12 AM GMT Low Tide 12.61 ft 7:33 AM GMT

A TWENTY-ONE FOOT difference between high and low tide? No wonder they were concerned enough to build a tracking device.

Good Grief! It gets worse ....

High Tide 43.88 ft (solstice full moon) Low Tide 4.99 ft

I can't think of a comparable USA site ...

San Francisco Bay is notorious for washing small boats out to sea when the tide is ebbing, but it doesn't strand them 30 feet above the water line. (although getting stuck for a few hours on the mud flats of South Bay is an olfactory experience to be avoided). You just have to stay well on the bay side of Alcatraz or have a really GOOD engine and a shallow draft to escape. Coast Guard cutters collect the flotsam out by the Farallons and come in at slack tide with a string of weekend sailors on a towline.

Savannah is tricky at ebb tide, but mostly because of the bridges, narrow channels, false swamp channels, and the river helping the tide go out ... my husband's 127-foot ship got turned sideways by an eddy as they were leaving their dock. Usually no problem because that ship could do a 360 degree turn, but the dock was only a couple hundred feet upriver of a 130-foot bridge span and the river was moving them briskly towards it. They made it through without losing any paint, using their bow and stern thrusters to stay stable, but they also made the evening news. A traffic helicopter spotted them and filmed the ship go under the bridge flat side first instead of pointy-end first. They were VERY glad the announcer said the ship belonged to the Coast Guard, got the pointy end aimed in the right direction, and left immediately before the harbor master figured out which ship is was and asked for a report.

Fresh-baked gingerbread is worth hoisting sail for. I've written the Assembly Rooms museum (in my long-lasting quest to determine the use of dance cards in Regency England) and would like to eventually make it across the pond. Bath and Bristol are high on my list of places to visit (with as much money as possible to enliven the local economy).

As with some of your other topics in the past, I was impressed with your knowledge of tides and ships movement and terminology, and then I got to the 'pointy end' terminology and ended up ROFLOL.

I sure do enjoy a good chuckle.
