Andy,
Tides permitting I like to get the anchor down and settle to a wreck.
The obvious candidates usually get a visit to see my boat such as eels (some very big), pout (smelly but good bait), ling (tasty) and Cod (once in a blue moon).
Interstingly though I have had my biggest Bass (14lb), biggest Pollack (17.5lb), biggest Black Bream (4lb 10onz) and biggest Tope (42lb) all whilst bait fishing wrecks at anchor!
I love drifting for Pollack and Bass too so i tend to drift whilst the tide is in full run and then get the hook down for the slacker times in the tide run thereby getting the best of both worlds.
Tight lines John
