A top window might be a good idea though, so you don't surface
underneath somebody

Dan, I'm interested in window size also. Here's what Sportsub,
http://www.sportsub.com, has to say about the size and placement of
windows in their subs:
Why are there no overhead or rear facing windows?
Any light that is allowed to enter the cockpit will cause reflections
and actually reduce visibility.
Detail: Most underwater environments are dimly lit because light
filters down from the surface. This surface light must be kept out of
the cockpit or it will cause reflections. It would be somewhat like
driving a car at night with the interior light on. Anything bright in
the cockpit would be reflected by the front windows, causing a ghost
image to appear in the pilot's field of view.

I ask this as most ambient designs seem to have steel or fibre glass
hulls
and still have tiny view ports. and since to me the attraction of
ambient
deisgns is the scope for larger less costly complex view ports and
far
greater visibilty I was just wondering why no-one seems to have done
this( I
could well be wrong)
