Well there are two "saxonia" sisters plus Britannic. Other companies I can make out are Head Line, Bibby, PSNC, Cunard cargo vessel and possibly Safmarine and an Indian vessel. best I can do - great photo.
PS just noticed a Blue Funnel far right
Cunarders probably "Carinthia" (1956) and "Sylvania" (1957). "Britannic" (scrapped 1960) would have been nudged in and out by tugs and warped. Bibby liner, inner dock on right looks like "Worcestershire"
