just stay within your comfort zone and be hyper aware of your surroundings and always be looking for potential situations. Wear your lanyard and wear it on your wrist, you will become use to it and are more likely notice if you forget to put it on (sort of how you notice when you dont have a seat belt on in your car). Seat time, seat time and more seat time. Personally i never mix alcohol and boating i really believe in zero tolerance for my self.
If you can, take one of Tres' driving schools. The knowledge and experience between him and Brad cannot be equaled anywhere else.
just dont get ahead of yourself and learn to read the conditions and the capabilities of you and your boat.
