So i was thinking, it would totally be easier on all the fisherman to have a fishing boat. Like, there's a little area to right click with an option to drive. And the reason I call them fishing boats is that you should be able to load crates on the boat and store fish in them. This is hard to explain. I'll try to show you...
Ctrl+left click on boat to stop driving and get out to check your nets.
Right Click Driving area to drive boat
