well there are many ways to sailfish one you can kite-fish. Two you can set your drift up deep and drift shallow with live baits. Three you can run up on them after you see one free-jump and put a bait in the area.
1. Kite-Fishing Usually depending on the wind you will use various weights of the kite and depending on you fish as many baits as possible on a single kite (The usuall is 2 to 3 baits, that mean 2 or 3 clips) After getting your kite up some people use a sea anchor to slow the drift. You can start your drift in depths from 80-160ft. And for the kind of tackle you can fish light 15-20lb spin gear and 20-30lb conventional gear. Usually people with have a bimini a few feet above their leader. After you have a bimini you can put heavier leader like 50 or 60 mono or flouro (your choice) so now you should have 6-10ft of a bimini and leader now hooks many tournements prefer circle hooks like size 5/0's to 7/0's.
2. Drifting with livies- You can start your drift from 80-160ft with maybe a deep rod set up on a down-rigger or if you dont have one a 2oz or 4oz lead and a leader, and when you put a deep rod out puts some wire like size 4-6wire incase of wahoo or kings. You can put out a flat line also no weight just a leader and bait. A float rod is a good choice to on the boat i work on we fish a long and short. Many species will find you that way dolphin, sails, tunas, kings, and maybe a wahoo.
3. When looking for an area to set up a drift you may see a sail free-jump get in that area and throw a couple chummies in the water to see if he there and in one of the chummies have a hooked one on a flat line rod. And hopefully he eats.
Good Luck
