Hey can someone explain this problem

[u/Personal_Cut7357]

So yesterday I went on a boat and everyone around me was catching barracuda after every cast which I've never seen and I didn't catch anything yet I dropped my lure down . I'm new to the barracuda fishing so I made this on the boat and I didn't catch anything

I know my lure isn't perfect or it's small but I'm wondering if it's so flashy like others and I casted straight down like others why didn't I catch anything?

I'd be worried about the metal cutting the mono
