Lake Otter

Hi and thanks in advance! I grew up fishing plastic worms and most things using what I consider the "typical" bass baitcaster that has the bail in the middle. Then, occasionally, I'd use the big round kind on salt water. But Dad has left behind baitcasting reels that are the round kind, like a hybrid between the two, with the bail off to the right, but smaller and seemingly for freshwater use. What on earth are they for? Example attached, thanks! I assume maybe they are for less frequent casting like live bait and trolling? Although Dad always wanted to troll with spinning reels...? I was used to using the kind for bass that Bill Dance would flip with or something, with the bail in the middle (not off to the side like the round kind in the pic). What did Dad intend to do with this kind of small but round baitcaster, on a FL lake or river?
