I own a fishing vessel which I use to catch fish.
That sounds quite exciting! I've only been on a boat a few times. What fish do you know about?
I am not an expert on fish, but I am an expert in the practice of catching fish.
Are there special tools you use?
I am old school, I catch fish by hand gathering.
Wow, you can catch fish by hand while you're on a boat?
Yes, but for you I suggest recreational fishing, so its pleasurable.
