Net profit is a nice name. I think anything with walleye, Erie or eye has likely been used. Have your name stand out and be unique to you and your boat.

If I was playing with that idea I would go with "Net Loss". After all, I did knock off one of True Blue's fish this season. And of course the expense of my fishing addiction.

I also had the idea of "poor-no-*" yes-pornostar but my wife shot that one down. That was a just for fun thing.
