Question – stand up gear for kids

Very last summer time I took my 7 12 months old son for a shark excursion where we got covered up in smaller blues and a couple mahi. He had a blast combating the sharks on 30s from rod holders and can’t wait to go once more. So I am pondering if I can rig up some light-weight standup tackle with a lighter jigging reel and short, light rod and find a smaller sized stand-up harness that he could fight with 5-seven lbs of drag. He is sixty lbs now so figuring 65 subsequent summertime and really powerful legs (ski racer).

Would enjoy any ideas from these who have experimented with it just before me for rod, reel and harness. If we operate this out there may well have to be a shakedown excursion to Costa Rica in April for screening purposes. Thank you in advance for the support.
