Thanks for the comments everyone. To answer some of the questions, I was fishing around the Hotwater outlet but the fish were scattered a bit. There was lots of surface action over a wide area (not confined to any structure though) and I figured that bigger things may be lurking below the tailor schools. The baitfish were about 3" long.
I have a Hobie Sports, Roberta and she's a great fishing platform. I've been out in the middle of the Bay in pretty choppy conditions and even up to a km or so off the heads, when the conditions are right, of course plus I always wear my PFD.
cheers,
Cid
