Marathon Shark Shore fishing - 21 Sep, 2018

Hi all
Once again this year (dec/jan) we will be back in glorious Marathon Fishing.  We rent a boat while we are there and shore fish for Redfish and Black drum etc but this year also fancy a change.  We wouldn't mind spending some evenings or early mornings trying for some shark and barracuda from the shore.  Any tips on tackle, bait, best places to fish (bay/ocean?) etc would be really really appreciated.  I dont expect to get your own personal spots just the type of area we should look for.
Thanks in advance 
Mike
