Hey guys. Sorry I was out last week on fall break with the kids.

I think all the questions have been answered but I will add a little just to be sure (because I like typing sooo much...haha)

As the other guys have said, predictive state works by "predicting" where the boat will be dynamically and moves the ballast when the boat is sitting still to try and get ballast correct before you ever take off. For example, if the Autowake is set to surf on the starboard side at 5 degrees to starboard, then based on our testing, we know the boat needs to be sitting close to 2.5 degrees to starboard so that once the boat gets going and flow plates are working, the boat should be close to 5 degrees. As I say all the time, the biggest confusion with surf boats these days are how passengers and gear affect displacement and roll. If all the passengers are sitting exactly level in the boat AND you have a cooler full of beer on the port side, then the boat is probably sitting at a roll TO the port side. It is almost impossible for a person to look at the boat and see a difference sitting still of 1 or 2 degrees. 1 or 2 degrees may not seem like much roll, but in the Surfing world, a half a degree of roll can be the difference in having a surf wave and NOT having a surf wave. So, before predictive state, with people sitting as described, the boat would take off, AutoWake would see that we are actually running at a 0 or 1 degree roll, and then it would have to drain ballast on the port side (assuming all ballast is full) to offset the passengers NOT sitting in the optimized spot. And this takes a while. While the ballast is moving, the rider is frustrated because the wave does not look good and I am sure everyone has been in this position. Then after a few minutes, the ballast has drained maybe 15-20% on the non surf side, the boat is sitting at proper roll and everything is relatively good.

The difference with predictive state is as soon as you turn the key on, AutoWake sees that you are sitting at the wrong roll. So, it starts draining on non surf side immediately. If you really want to be an expert driver, then the driver sees this and immediately knows that we should actually move passengers toward side with 100% ballast, moves a passenger to starboard side, predictive state shows you are good on roll, you take off, the wave is perfect and with passengers sitting in optimized locations, you also have max displacement. Lets say the driver doesn't look at the dash or no one wants to move. Again, no problem, while the rider is getting ready with jacket, rope, drinking his last sip of beverage, etc, the ballast is moving and now with 6 pumps, within a minute or so, predictive state has roll correct and as soon as you take off, the wave is correct.

Again, all that was in 2018, but if people were confused about how it works, hopefully that gives more clarity.

As to 2019, the biggest change was the ballast sensors. Again, I think that has been covered, but on most boats, the rear sensors are tubes that measures the actual level of the water. Currently, the software is setup so that when the bags are completely full in the rear, because the sensor sees it is full, then it turns off pumps and resets gauge to 100%. On some boats, the rear sensors and front sensors are flow sensors that measure when water starts to flow out the overflow. Those work similar in that when the ballast is full and flowing out, then it turns pump off and resets gauges so that you can not OVERFILL the ballast and cause other issues like busted bags or fittings. We do have several things in the works for the future, but we don't want to show our hand on all that yet. Believe it or not, sometimes our competitors go on this forum just to see if they can learn anything so not planning on giving them too much info. Just know that we are trying to keep pushing the envelope on technology that actually helps. While the other guys are working on louder stereos, fancy strobing RGB lights, and seats that are electric, cooled and heated, we are trying to keep focusing on actual performance related stuff. We assume that is why people are buying tow boats in the first place....

Ok, hope that helps. Got to get back to work... Hope we have a short winter. hahaha
