My first thought is go smaller, MUCH smaller with your lure choice. As in down to 10-20g. Harder to cast but most likely closer to the size of bait they're feeding on. I'd say if they were there through winter that they'd be mac tuna or bonito however at this stage of the season it could be longtails or even school or spotty macs. Could you visibly see the fish jumping out of the water after the baitfish or did they just "slash" the surface?
There's a lot of info online about boat positioning, how to approach feeding schools and lure sizes/techniques. Mostly tuna will feed into the wind as a general rule (but they'll break the rule if you follow them, guaranteed) and often they're feeding on tiny whitebait.
Both the lures you're using are good lures, just probably need to be smaller and have a subtle approach. Sometimes vary the retrieve, not always a flat out retrieve, sometimes let it sink below the school and wind, sometimes wind from the wides in a stop/start, sometimes slow and other times just at warp speed.
They're a prick to chase because they will frustrate you 99 times out of 100. Goodluck though!
