To reafirm the point Manx Fisher made.
After repeatedly casting as far as I could without success - the biggest Pollock I ever hooked, took my lure within ten feet of where I was.
It is more important to search around the features of where you are, than it is to cast as far as possible. Look for currents, eddys, swirls, kelp beds, rock formations etc. Try to search them all (without getting snagged all the time if possible).
As Manx said - casting sideways along rock formations and reefs can be very productive.
Don't always just retrieve your lure straight in. Try different speeds, try jerking the line, try sink and draw - try anything - you will find what works best in time.
You may have Bass where you are, which I have no experience of, but I use all of the above for Pollock and summer codling.
