A simple program which works out a tide table based on the nearest high and low tides. It uses the assumption that the tide rises in a sine curve (see graph above) which is fairly accurate in most cases. But, like all tide calculations, it is an approximation and should be treated likewise.
How to use:
NB. There is little error checking on the program, ie. there is nothing to stop you entering 65 minutes or 25 hours. A good navigator should double-check his figures anyway.
