This rig can actually be pre-rigged and stored in bags, making it much quicker to change rigs when the action hots up. Another tip is to clip the fins of an over active bait, especially when chasing mackerel. These speedsters often overrun a quick turning bait. As they are hit and run merchants, they will often keep going rather than double back for a pittance of an offering. The other can be 20 to 30 metres back, set down deeper, three to four metres, with use of a small weight.
Outriggers come in very handy for setting baits further apart.
The down side is that they can be a nuisance if the fish decides to do a few laps around the boat. Too many lines out and the end result can often look like a may pole. Keep a den buoy handy if you have to chase a big fish and always be alert for the unexpected. I've had some monster sharks give the boat a nudge while berrying and crossed paths with a killer whale on one occasion. The reward of a big fish is well worth the patience and effort put in.
