Center Console Boats And More

It’s Official! I need help…?

My party is going to be on a pontoon boat and we're tubing. Well, I think everything is going to be fine since its going to be a bunch of 14 year olds. And everybody knows that we can make a conversation about anything. But my mom thinks there is something we need to do ON the boat so we don't get bored for 4 hours. Got any ideas??
