Cracked fin still rideable?

[leBoss11]

Hi everyone, I'm new to surfing and recently found a surfboard in the trash, I refurbished it and realized a crack down the middle of a fin. Would something like this still be ride-able??

Is the crack all the way through ie the fin is split in half?

In any case you can repair it and try it out

Looks like it’s a glassed in fin but even those can be replaced if needed
