Gidday Vance,
Thanks for the reccomendation. Amazon is looking for a copy for me, sounds
like a book well worth having.
Actually, it was not a corrosion problem I was concerned with. It was the
situation of, if you are looking 'through' the front ballast tank as with
the Delta, with water rising and falling between dives, you could get a
build up of salt and sea muck. On the surface, the chamber would be full of
air so marine growth would not be a problem (a few days submerged might be
different), a dive over the side nearly every day with a cloth should keep
it clean. I bet you have thought about this Carsten ?
