Bull arab?

Am I right in my assumption that bull Arabs are sighthound type dogs? I have noticed a lot of Australian photos where dogs ride hoods til the hunters spot a pig. That's basically what I tried with gator a few weeks ago and though it worked well twice the third time he ignored the little pig at the feeder and made a 1/2 mile beeline to a bad boy and niether he nor the boar made much noise and by the time I got to him we were all three tuckered out. In theory I would love a bad ace bull Arab but wouldn't they require daylight and open country?
