Yes, when a chart says 65' for 15' of depth, you let out 65' then attach your board, speed and line diameter play a big part too. Most lures work optimally at 1.5 mph, some slower , some a touch faster. Try to keep your bait 4-7 ft above the fish and try different speeds and slow turns. Whatever works, duplicate it. when guys say 2oz. 30/30, they mean using a 2 oz weight, you let out 30' of line attach your 2 oz weight, then another 30' of line, then hook on your board. Mike
