Subject: tidal heights calculations...
From: Russell Sher (rsher@XXX.XXX)

A friends of mine recently did a nav. theory course in which she said the
'rule of twelfths' is no longer taught for tidal calculations. Instead,
percentages are used. Has anybody heard of this? - Would that mean 10%, 15%,
25%, 25%, 25% 10% instead of 1,2, 3, 3, 2, 1 (in twelfths)?
Regards
Russell
