- This is !Tides, Version 1.3 (27 Sep. 1996)
-
- Use
- =========
- Perhaps there is no use for this program. It is of interest to me, and I
- would love to find the methods of accurate tide prediction. This is not
- accurate, though it never gets too far from the normal tide predictions
- at Clacton.
-
- Explanation
- ============
- John Collier writes in the Compendium Artis
- Nauticae, published in 1729-
-
- "Each problem of navigation, is rendered intelligible to the meanest
- capacity. Rule:divide the date of the year by 19, add one to the remainder,
- and you have the Golden number; multiply that Golden number by 11 and divide
- the product by 30, the remainderis the epact.... To the epact add , in the
- month of January 0, February 2, March 1, April 0, May 3, June 4, July 5,
- August 6, September 8, October 8, November 10 , December 10 and the day of
- the month, if this sum is less than 30 it is the moon's age; if greater than
- 30 subtract 30 from it, and the remainder is the moon's age. Multiply the
- moon's age by 4 and divide the product by 5, the quotient are the hours,
- and the remainder are the minutes of the moon's southing."
-
- The author adds laconically :
-
- "Note While the moon is in the increase she souths, before midnight; while
- she is decreasing she souths before noon. These things are known by every
- cabbin boy, colliers nag and waterman's servant, and therefore needs no
- further explanation."
-
- Good stuff for a computer!
-
- Disclaimer
- ==========
- Please don't use this as an accurate predicter of tides. It usually seems to
- be within an hour of the correct time at Clacton.
-
- Customising
- ===========
-
- If you want a customised version for your pet fishing village, send me the
- difference in time of tide between there and Dover.
