Big gear ,big leads by the end of aug 100' + is not very deep . A proper hand held gps is crucial for speed a portable sounder also makes a huge differance . Get boat to speed 2.0 mph ---4.0 mph then drop lines off the upper deck as far forad as is safe . This lets you use the portable sounder off the stern to help "see" what depth you getting for that drop back ie 40' ↓ 40'→ with 4oz at 2.8 mph so 60pulls = 120 ' with 4oz would get 120' down give or take . This math is just for example. Once lines are run I used small bunggies to hold rods off the hand rail with boards out we managed 8 lines lol. Good luck BD13 will have better info for lures and such as he has lots more time on the shoe.
