Hello JS109,
I am no pro on a boat but have been out targeting them from a kayak and from a ski boat... They are really easy to catch and you can use either lures or livebait with livies being the best for me. But make no mistake they are very easy to catch on a lure!!!!
With the livies I make a chin weight or I put a ball sinker(1oz) sliding and a swivel and make a 800mm-1m fluaro leader and put a 3angel hoek in its mouth... Then you work just behind the waves as near the side as you can and you troll the livie very very very slow... You can use keratien, sand steenbras, mullet, mackerel, pinkies and do not be scared to use biiiggg livies, especially mullet. They very often knock it and miss the hook, then put the motors in neutral and he will return to collect its food... Then you hold on as the biigg ones pull damn hard!!!
Post some pics and please keep to responsible fishing!!!
