I see the term "cattle boat" tossed around a bunch. But I am not seeing any consistency. Is it number of divers or the fact that the divers are "herded along", that is all divers are in guided groups?
Personally I am not a fan of six packs and also not a fan of group guided dives. (Individual or buddy pair guides is fine).
