    08 RZ2 or new owners weighting the boat

    Hello everyone,
    I'm coming from an 01 21V. I thought weighting it was pretty easy.
    Now this RZ2 is way different, I have the stock ballast 2 hard tanks and a V bag up front. Which I think totals 900#. Most of that in the bow.
    With the hard tanks the rear lockers are not big at all so my large Flying high, around 800# won't fit. I could put that next to a seat. I do have a couple smaller one's, 1-250# I think the other around 400#.
    Do they make a large bag that will fit in the locker and just extends most of the way forward?
    How does every one else weight? I think this thing can throw a nice wave, I'm just not there.

    Thanks

    Get ahold of chpthril, he helped me get bags for my 08 RZ4. I am sure you can get 750# or more in each locker with the right bags. I plumbed mine in to the factory fill pumps with "Y" fittings and some butterfly valves to control flow so that my bags fill in the same time as the hard tanks (divert most of the water to the bags) then I added a larger drain pump for each bag and wired them into the same circuit as the rear drain pumps. This allows me to fill and drain the bags using the stock switches. I added some check valves to prevent passive draining, put another "Y" fitting into the existing vent lines from the hard ranks and had to cut a hole on each side for the new drain line from each bag.
    All in it took me a day to get it all done (take a hair dryer into the boat with you to help get the fittings on the hoses). I am very happy with the results. The weight was good when I was listing the boat for a surf wave and now I fill up both sides 2000# total and just move my wake shaper back and forth.

    I still can't seem to get the Wake dialed in, it appears to me that the RZ2 want a lot of weight up front? Would other owners agree?
    I went out Wed the wake wasn't bad, just not very long, stock ballast and I added another 600# on the Port side under the seats. I'm thinking putting my last bag in the walk way.

    Thoughts?

    Speed and TAPS will also play a role in lengthening the pocket, along with bow weight. You are going to need as much weight as possible in the rear surf side, before adding too much bow weight though.

    Yes, there is a custom sac that will fit that boat.

    So you did not mention whether you are weighting for surf or wakeboarding. You weight totally different for each discipline. Properly weighted that boat can make a fantastic wave. Not so much with the stock ballast but with added. Get ahold of chpthril and he can get you lined out with bags that will fit your boat. Just a quick search will show how others weight that boat. General rule for surfing is weight as much as possible in the back surf side then add weight up front till the wave is to your liking. Speed is around 10.8 to 11.4 with taps in the range of 3.5 to 6.5. For wakeboarding sack it both front and back and go from there.

    I will say I don't have a bag directly in the rear locker. That locker is small, I only have bags along the port side under the seat.
    I can try and move them farther back. I also have a large 700# bag but I don't think it will fit. It may help just filling as much as I can.
    This is for a surf set up.

    Thanks again.

    has to be in the lockers or forget about it, these boats like weight, if you are surfing.

    You really need to pull out the factory hard tanks and move the batteries to somewhere else to open up space in the lockers. Then you'll have plenty of room for bags in there. I'd recommend getting custom sacs or if your cheap like me a 1100lb sac will fit. It won't fill all the way but I'd bet mine fill to 85% or more.

    I'm probably in the minority here but I fill my front sac as full as it will go. I stop filling when my front cup holders pop out. Then as much weight as I can on the side I'm surfing. Sometimes I add a little off side weight to get things how I want it. With my setup (1100s in the back and some tractor weights) I get a pretty respectable wave. Not as big as some of the guys with custom sacs but it works fine for us.

    Does anyone have a diagram and parts required to plump ballast sacks into factory tanks?

    I found for my RZ2 that slowing down to 10.4 helped SIGNIFICANTLY! I couldn't believe the difference slowing down made. I had TAPS3 at 7 or 8 and TAPS 3 wit ballast 100% full in all four bags (2015 RZ2, not sure if it has the Surf XL yet or not - I just got it less than a week ago). What also helped was having me or a buddy instructing from the back most corner possible.

    Makes me think 200lbs of lead in each rear locker put as far back as possible will help make it that much easier to dial in!
