Fishing Tournament

This is my first time making a map. So, anyways, in this map, in order to win, you must get the most fish in the limited time. Someone has to choose the time limit. Someone. Sorry, because I have no idea on how to make a Redstone clock nor a complex Redstone contraption. :( Sad, isn't it? Yeah who cares. LOL. So, there are some small boats provided for you. You can ride on those, OR, you can ride the decorative boats build in the sea if you want. Luxury boats, ugly looking boats, Police Boats (it's weird to go fishing in a police boat), etc.
