there were a couple of each, baba and tayana at my old marina and they all sailed very well...as you mention they are not racers. The one baba I sailed on did use double head sails in light winds and the captain was very capable.
Not sure of the speed, but down the bay and back there was no need to motor with 10 knots of wind.
well founded boat, well built, is for sale IIRC,

the tayana next to my old slip is for sale as well, again a well done boat, this one needs some TLC
