Lest we assume too much knowledge of jargon, the term "cattle boat" is a disparaging term that some divers use to refer to a boat on which divers might feel like they are being herded like cattle. You can look up previous threads in which people have debated the precise definition, but the gist of it is the feeling of being herded like cattle. For example, in some instances the boat is large, every seat is filled, all divers are required to follow a divemaster, and the ratio of divers to divemaster(s) is high. Of course, a large boat does not by itself mean anything. The boat may simply be spacious. Even a large boat with every seat filled may not leave divers feeling herded like cattle: In some places in the world, it is not the norm for a divemaster to even accompany divers, which means you and your buddy can go off and dive in peace.
The terms "cattle boat" and "six pack" are sometimes used to refer to the opposite ends of the spectrum, as though those are your only choices. In reality, there may be other options in between. Do your homework and choose dive ops to fit what you prefer.
