Tackle, at least a 12ft beach caster, and your own choice of reel. A 14-20lb line would be an advantage, as some large flats, congers, cod and pollack can be caught.
Bait...Mackerel, Lugworm, Rag, Squid, Crab
Feathers are good in mackerel season, especially off the break water. Same with shiney lures, again break water.
It's been known that Ling and Bass are caught frequently, however I've only seen 1 off each on outings.
Read up on the tides, as it makes all the difference. Its been so long since I've done sea fishing..I can barely remember the ins and outs.
Wouldn't bother with a float, just perch the rod up high and watch for bites.
Rocks off boddam are the best, especially round by the power station! Lobsters/Crabs frequent the water outlet as its warm.
