Enzo is a beautiful dog. I hope you can train him to meet your goals. I think dogs like to have a job and be told what to do. I bet he would like obedience. You asked if someone knows where you can train him, I would suggest obedience class.
Sharon is right, a disobedient duck dog can be dangerous. Did you watch Evan's video? Guns + boat + disobedient dog = disaster. And disobedient hunting dogs usually harass and chase wildlife (bad and illegal) instead of do their jobs.
The video gave a great tip how to get a wet dog into the boat w/out tipping it. The video makes it look so easy.
