    Catching up

    I have been crazy busy since the Polar Bear event, and haven't been on here much, I miss it. But thought I would catch up on a few things.

    First, if you didn't get to watch the videos and read the rider's comments from the Polar Bear event, you should check them out.

    There are 4 videos, thousands of pics, and stats and commets from riders. The RZ2 wake was a hit, made us proud, and was the only boat out there with a fully automated competition wake. Not to say that others can't automate, but not by only replacing the rear sacs so easily. Anyway, great time, and the RZ2 showed its ability as a world class wakesurf boat.

    One of the things that came from the event, is several people thought the enzo or supreme wake was a bit longer and liked that. Asked me why the RZ2 wake was not. I told them our wake is what RJ likes, but we can make it longer, but I was a bit curious just what it would do if we sped up a bit and added some weight up front. So RJ and I went out with Max, T-Bone and Jess and did some tests. The cool part was how we used 2 angles with 2 cameras. It was a lot of fun, check it out.

    Very cool ragboy.

    Perhaps next time you should try and get an actual measurement of the pocket length (transom to backfoot in the curl for example). That way we can compare ballast setups with different/same boats a bit better.

      Great results! These experiments are very useful

      Dropped the pump in the lake, eh? Now we now why a full auto system is important to you guys!

      How did you mount the top camera? To the tow point?

        Nice vids. Pretty informative. Seems like we need to try some weight up front as you seem to have 400 in the front normally and then added another 400 if I'm understanding correctly.

        One question - do you have any weight on the opposite side as the surf side. Seems to me remembering that if we weighted the boat too much to one side then we would cavitate some. Any recommendations on this. Also, that 1600lbs you have in the back corner - is that all in one corner or spread a little bit to the non surf side? Kind of the same question I guess. Any help would be great.

          I even bought the rope to measure. The thing is, unless I figure out a way to make it universal, its kinda moot. The riders would have to be same size and skill, or some way to measure without a rider. Then the issue is "useable pocket". For instance, the way the curl forms at the back is a big deal. If it is large, it grabs your leg, if not, you can ride back farther. But I am trying to work that out.

          Yeah, was pretty funny. I have another, but had the pump in the water, other end on bag. Disconnected from bag without thinking. D'oh! Top camera was mounted with my suction cup on top of alpha z tower.

          No weight on opposite side except my stick of a daughter maddie driving. 1600 lbs includes me, 1200 in water ballast, some going under my but under the seat. It may have been as much as 1700. Up front, 400 in tank on surf side, 400 lb sac on seat up front on surf side for the 13mph test. On 12mph test, no sac on front seat.

          We had a lot of fun with the DVD style commentary.

            Even just a basic measurement from the transom lift eye (about the same on every boat) to the kickpad on the board once the curl hits it. Then it doesn't matter about weight or skill level of the rider.

              If weight doesn't matter, then what's the purpose of the measurement comparing different boats? I could see using the difference in distance to show how adding bow weight lengthened the pocket on a particular boat.

                Weight matters, board matters, many factors allow you to go farther back.

                  Measuring pocket length can be made as technical or as simple as you want. I tend to like simple things, that way more people can and will do it, therefore giving more data.

                  This doesn't mean that rider weight and board can't be stated, or if the wave was/wasn't surfable or not.

                  It is only length

                  The difficult one to quantify is 'push'....

                      True, when I do start measuring, I want it to be a method that can be done across boats.

                        Thank you Ragboy. I really appreciate you letting me know how you weight your boat. I know it's a little different per boat but it gives me a better idea where to maybe make improvements.

                        And thanks for providing the vid. It was nice and informative. I think it did just what you wanted. Look forward to more.

                          very helpful. I don't have the RZ2 (22V) but I will have to experiment with more front weight and more speed.
                          It actually looks from the video like the 13MPH wave is a bit taller and of course longer. thanks for the info.
