Perfectly normal depending on sea state. 16 kn is correct for glassy seas, 12 - 13 is right for heavier seas.

The XXI is faster submerged than surfaced. At every bell, iirc.

The XXI was designed with a whole slough of advancements over previous designs, surfaced speed wasn't one of them.

And, as Fubar mentioned, charging the batteries slows the boat a bit.
