Don't expect to be very impressed with the surfing wave with the stock ballast. I have a 2006 V215 and from what i hear the surf wave is one of the best after you add the right weight. With the stock ballast I would surf around 9.3-9.5 but if you don't have at least 4 people in the boat it gets to be kinda hard to keep up with the boat. I am going to replace my stock tanks with 750lb sacs and that should get me a good wave hopefully
