Sea Quest

Was fishing for squid on Saturday got a few and noticed a coupleother boats in the area did as well,another large boat come on the scene. Within half an hour they would of had 30 or 40 squid ,were smashing them. They were definetly doing something different than the other four boats around.I have heard of dipping jigs in Tuna Oil but surely these guys are onto something else look like a pro boat, any ideas what their secret is?
