    Hear hear DD.  Apart from anything else, with a sailing boat it is often not possible to lay off a desired course and keep to it, since the wind may not oblige.

    Another fine theory in principle, that does not work out practically.

    Even when allowing for tidal streams every half hour with the DR plot as I used to do,  there can still be differences appearing which make the passage lop-sided as you cross, but one thing is certain - this gives a much better end result than a 'straight ahead' strategy over the tidal cycle.  There are too many  variables for such a simplistic approach.
