I found out, that the XXI sails much better at surface, when I go decks-awash.
The forw.diving-planes stay extracted, and help to keep the boat stable...and fuel-consumption isn't a big deal, as the hull-design actually helps in this condition.
One thing, though: I went to decks-awash while surfacing...that way, the forw.planes didn't retract.
I wouldn't be surprised (haven't tried yet), if they stayed retracted, when going to decks-awash from fully-surfaced.
Now I'm trying to find a way, to have the
FuMB37 Leros on the schnorkel in July'44...can someone help me?
