How much bigger than the dolphins were they? One possibility is
Long-finned Pilot Whales where the male has a more bulbous and swept-back
dorsal fin than the female; the colour is jet black or dark grey, but can
appear chocolate brown. The adult size range is 3.8-6m long which could
explain the size difference you saw; an adult with young in another option.
It may also be that the floppy fin was actually a flipper - I've seen
Humpback Whales "waving" on a Wollongong pelagic trip, and with some
cetaceans they could be mistaken for a fin.
BTW, the information above is taken from the Collins Eyewitness Handbook
"Whales, Dolphins and Porpoises" by Mark Carwardine, published in 1995 by
Harper Collins. It is an excellent field guide to cetaceans - the best
I have seen, and around $30. It has a useful identification key at the
front with the cetaceans sorted by size groups, and detailed individual
species accounts with key features highlighted, colour variations,
behaviours etc. It even includes details of Longman's Beaked Whale,
which is known only from two skulls (one from Mackay in 1882), and an
unidentified beaked whale known only from 30 reported sightings at sea.
Well worth buying!
