Thank you very much!
( It is a different Cartwright, but still I am interested in this paper).

Alex.

W. H. Munk & D. E. Cartwright, 'Tidal spectroscopy and prediction' 
Philosophical Transactions of the Royal Society of London, A259 (1966) 
p.533-81. Walter and David gained a fellowship each for their combined work 
on the black-box response method. David died about five years ago. Easier 
going might be one of the more recent monographs by D. T. Pugh. For a 
realistic approximation only four components are usually needed: M2, S2, M1 & 
O2. Easiest of all may well be to just match a prediction in the Admiralty 
Tide Tables for any recent year for your port, with a similar lunar condition 
of phase and declination for about that time of year needed. NOAA's website 
run by Fred Espinac provides good proleptic lunar data, as does any early 
nineteenth century simple almanac provide contemporary data.
