Actually just tested just that out of curiosity, Krave is much slower tacking at half wind speed. I think either wiki numbers are too optimistic or tack angle before speed loss is a little more than 45degrees.
I would not be surprised if Krave was slower tacking even at max wind...

Longboat is still good but might be clsoer than it reads from wiki / feels too.
