Are these good for fishing?

Apologies for coming off as uneducated. I have no experience with kayak fishing.

A family member has offered me these kayaks. I’d just have to drive and pick them up. Are these any good for fishing? If not, is there anything I could modify to make them great fishing vessels? They said they’ve only used them a couple of times and they’ve been sitting on the dock unused for a couple of years.

I’ve always wanted to get into this hobby, but between work and my other hobbies, I could never justify spending the money to enter the kayak fishing realm. Thank you in advance for your knowledge!
