Since catching all the fish that matter, my boat has since gotten the ability to traverse concrete. I have decided to park my boat on top of the walls and hang up my fishing gear. Awaiting newer and bigger fish... Hopefully not a land shark.
I found a work around for the bug that reduces your dmg upon reloading. If you are experiencing this just add a skill that you haven't leveled up to your bar. It doesn't have to be one you can use. So long as it levels up you should see your dmg go back to normal.
A fine day's work for a fishing legend!
