I have just spent a weekend fishing in Donegal and taken mackerel, pollack, gurnard and dab all on a variety of baits from the boat. However I spent more time untangling my rigs than having my bait in the water, so I think I need some advice on effective boat rigs

So can you suggest me some rigs I should pick up and what species they would target. I can fish over clean or rough ground and there are quite a number of different fish around Dunfanaghy, Port Na Blah, Downings etc.
Cheers
