Bass, mackerel, pollock and garfish in the race near the ferry. Trundle worm baits along the bottom for a few plaice, gurnard and occasionally wrasse fishing into the harbour. Very weedy, especially so when tide is ripping through. Most people fish plastics for bass. 20g Tobies seem to work for mackerel.
Outside the race it's a bit patchy but there's sometimes smoothies, rays, turbot and bass. Over towards the Studland beaches there are mullet, especially in the corner at Middle Beach, and the jetties and rocks on the Sandbanks side are also mullet central. The beach is quite shallow at Shell Bay but there's a ruined training wall which sometimes brings bass very close in.
I've always had better luck over in Mudeford or Hengistbury.
