[PSUBS-MAILIST] Pressure Chamber

[James Frankland via Personal_Submersibles]

I empty the tank before diving of course to save most of the stuff.  Only
problem is its a bit slimy, so any left in the tank can slime up the
underside of the boat on the first purge.  However, ive found that by
purging the tank while driving forward gets rid of it without it glooping
all over the hull.  Once its flushed though once, its all gone.
