Hey guys! I have been emailing several different people and I have realized that maybe we didn't do the best job at explaining displacement / amplitude bar / and wake size expectations. I have shared this with a few of you, but thought the entire group could benefit or learn from this explanation. As I have said many times in the past, in surfing there is one critical rule and that is there is NO replacement for displacement. AutoWake adjusts ballast and helps you move passengers to achieve proper pitch and roll, but that is only 2 of the 3 critical variables. Pitch and Roll define shape, and shape is very important, but NOTHING is more important that displacement. That is why for 2018 we have the new (recently patented!) amplitude bar. I have slightly modified the amplitude bar and I think this might help some of you understand better how displacement works. Here is the bar...

Every model is different but lets take a Craz for example. On the 2018 Craz, the boat has a ballast capacity of 3,000lbs. The boat also has capacity for an additional 2,400lbs of passengers/gear. So, the overall capacity of displacement (legally) is 5,400lbs. Let's break that down into the sections that are shown on this bar graph. The lower third would be approximately 0-1800lbs of displacement. The middle third would be approximately 1801-3600lbs of displacement. The Upper third would be approximately 3601-5400lbs. These sections should allow you to set your expectations on wake size. Think of it like small, medium, or large. Or maybe even like ski, board, surf. This doesn't apply to everyone as some people can surf a small wave or ski a large wake, but for the majority of people looking to have a "decent" size surf wave, you should really get your displacement in the upper third of displacement. PLUS, the larger the rider, the higher up the displacement needs to be. The smaller the board, the higher up the displacement needs to be. And the opposite is true, if you are a smaller rider, then you can get away with less displacement, or if you have a larger board, then again you can get away with less displacement. And this same theory holds true for smaller boats. Like in the case of the Mondo. That boat has a total capacity of 4300lbs. Using same logic, because of the smaller hull and running surface, you can actually run less overall displacement, but you still need to be in the upper third. So, in that boat, you really need to be in the 3,000lb displacement range at least.
I think many people lost track of displacement and only thought about pitch and roll. But displacement is the real key and if you let it, AutoWake can TEACH you how to optimize passenger location to achieve max displacement AND get the correct pitch and roll. As some have explained before, a good way to do that is watch how AutoWake adjusts ballast for you. If AutoWake drains weight in the front, then move weight to the rear. If AutoWake drains weight on the port side, then move weight to starboard. The basic rule of thumb is ALWAYS move passengers to the area of the boat where ballast is 100% full. AND that includes moving weight front or back. Once you learn how to do that, then AutoWake will make sure you have exactly the correct pitch and roll AND it will help you optimize passenger location to get 100% max displacement. What you will find is the lower you are on the displacement amplitude scale, the more critical optimizing passenger location will be. If you are running a potential of 6,000lbs of ballast/lead/passengers, then optimizing passenger location is NOT as critical since you are very high on the amplitude bar. But if you are running in that middle section of amplitude and you are trying to optimize the best wave you can that day, I highly recommend letting AutoWake help you get 100% of your potential you can.
One last comment I want to address is I have heard many people say they prefer to manually adjust and don't use AutoWake. To those people, if you are getting good performance, then I say go for it and have fun. But this would be my suggestion... If you are comfortable moving passengers then why wouldn't you let AutoWake help recommend where to put those passengers? If you are filling all ballast to 100%, then moving passengers to get the wave correct (getting correct pitch and roll), then why not check your pitch and roll and mentally make a note of those values. I would make a bet that if you did that over and over, you would find that when you get the wave "correct" you are probably duplicating the same pitch and roll each time. AND, I would bet that if you let AutoWake help you do that, you would find the wave to be even MORE consistent then manually doing the trial and error method of slightly moving one person at a time. But, again, we know that AutoWake is not for everyone. And if you are having a great time on your boat and spending time with your family, then that is really all that matters. Sorry I got long winded on this one, just thought these tid bits of info might help some of you as you keep learning more about AutoWake this summer!! Have a safe and fun time out there!!
