Ok, Lots of interesting banter, but not much discussion about the question, at least the way I thought I asked it.
So some more clarification. Roller furling, so no hauling of sails. I won't ever have this hatch open while sailing, at least not unless it is really light calm conditions.
The question was, with the hinges forward, hatch open 90 degrees and the companionway open (under a dodger) would the airflow at ANCHOR (again, not sailing, for you speed readers) be better, then having the opening of the hatch facing forward.
This is a Lewmar Ocean 60 hatch, and is level with the deck.\, raise a few inches.
Here is a photo of the old hatch, in the original orientation.
