1) The concept of being too warm on a dive blows my mind. I obviously need to travel more.
2) Can you explain "heat index"?
3) Rather than build an AC unit with an integral reservoir for the condensed water, one might consider simply pumping any condensate to your VBT, if so equipped.

To say that I could have used small AC unit in the boat is an understatement!  One of the implications of this cabin environment was that I could not keep the viewport clear.  I soaked the towels I had on board very quickly trying to clear the viewport.  As a consequence, is was hard to see.

The unit is going to have a reservoir for capturing quite a bit of condensed water extracted over say a 6 hour design mission time.  For my boat the unit would need to be small and compact.  Would be nice if we could find a OTS small compact AC unit that was DC powered.
