8-9 knots a mix of ballyhoo behind seawitchs and islanders and artifical lures.
Most of our artificals are witches, islanders, jet heads and Big T straight runners w/ 7"-8" rubber skirts. We use 9/0 - 10/0 hooks - Mustad 7691S for the plastics and 7690DT for the baits. 2 30-w's w/ 60lb top shots attached via rubber bands to the down riggers (12lb lead balls) and 50's w/ 80lb topshots for the 2 riggers and bridge rod. 6 - 8oz trolling weights on the rigger rods and at least 20 lbs of drag on everything....it's all about Penatration !!!

the above was taken from the 'wahoo spread' thread...

On a sailboat in the islands, I'd recomend trolling closer to 9/10knots with straight running artifical lures w/ single hooks on trolling weights. The barracudas will eat you up down south if you troll too slow..
