Fished out of mackay for last decade.
You need a fast boat with lots of range if you want to maximise this area. 120k-160km out if your keen.
most sharkcats have to small fuel tank.
I fished out of a 560 sharkcat for a few years but it had new 220l tanks each side. Awesome boat for offshore fishing and the safety of twins when out really far is excellent.
If you buy a boat for mackay make sure it has big range and bit of speed or you.ll regret it.
Nothing worse than a 100km trip back at 20 knots on a sunday afternoon
