might be worth getting a beachcaster/skyliner pod that would help a bit, other than that sounds like you need a long snag leader, have a look at what there is for the big catfish on the Ebro.

Solar do line biters which slide down from the rod tip, used at Rainbow in France. Talking of which there are a number of homemade contraptions, like swivels fitted into coke bottles to keep the line up. You can also use suspender floats, or predator inline sunk floats, but these do cut down casting distance, but with a boat you can put them the distance. On Alton near concrete blocks I had to use a long snag leader of 30lb Amnesia to stop cutoffs
