View Full Version : 230vs ballast/ fatsacs?

05-15-2014, 06:01 AM
Hey guys Im wanting to eventually install ballast system but for now I'm just wanting to get some bags that I can fill for now then convert the bags to ballast when I get time.I'm wanting enough weight to surf. What bags can I manually fill now and if I want I can convert the same bags to ballast? I have 2001 230vs.

you can fit off the shelf 1100's in the rear lockers and a 750 off the shelf fits OK in the bow walkway. the surfing pic is with the 1100 in the port corner and the stock KGB ~350# full but no external sacs. in an ideal world, i'd have the 1100's in the corners, a custom wake makers bag in the ski locker and a bow filler sac plumbed in as well. fwiw, our hulls are identical.

That's one of the best waves I've seen for that year hull. Nice job!

I have 750s in the rear (950 lbs "fully expanded") and a 650 U shaped sac under the front seats that are fully automated (i.e. flip a switch to fill/drain). I also have a 280 lbs sac that I just fill at the beginning of the season in the front of the ski locker and leave full. I had another 280 filled/drained via a portable pump that I'd put in the walkway sometimes if we wanted a lot of weight for wakeboarding or I'd put it on the surf side towards the rear for surfing.


It took some dialing in but for the last couple of seasons it just works and I don't really have to think about it. If you're all about the surfing then I'd get the 1100s for the rear. They'll fit but you won't get them fully "plumped" like you can with the 750s. You might get close to the 1,100 lb nominal weight but you certainly won't get more than that (i.e. you will only fit maybe 150 more lbs in an "1100 lb sac" vs. the expanded "750 lb sac") due to the size of the locker.

Here's the wakeboard wake:

I don't have any pictures of the surf wave. I really just set it up for surfing on a "best effort" basis since I don't particularly care for it. It does work fine though.

Also, I don't typically fill the rear completely for wakeboarding. I'll get them close to "full" but certainly not "expanded" (The term FlyHigh/FatSac uses) so they're probably around 700 lbs each for wakeboarding. For surfing I fill the bag to the full 950 lb expanded weight, put the 280 on the floor on the surf side rear corner and partially fill the bow sac sometimes.

1100 sacks 80% filled on each side in the rear compartments correct?

i guess will need to relocate the dual batteries.. where should i put the 2 batteries?

I only have one battery in the factory location below the port, rear corner seat. If I was going to add a second battery I'd just do dual group 27s which should fit in there. If you have group 29 or 31s then you won't fit two under that seat. You could get smaller batteries or ditch the cooler and put one in the starboard rear corner seat.

Also, do you have the motorized actuator for the rear hatch? If so that will interfere with the port side sac. You'll either need to build something around it to allow it to move while the sac is filled or just get rid of it and do this:

I have two batteries, 24 size, under the rear seat on the port side. They are just before where the floor rasies up under the seat. They fit fine with 1,100 in the lockers.

So, if you want to buy a setup that can be filled with a portable pump now and then plumbed in later here's what I'd do.

If you're a big surfer then get this:

If it's mostly for wakeboarding with a little bit of surfing get this and save $80:

Then get this integrated bow sac:

That will get you going but you certainly will not be able to fill either of those rear sacs full for wakeboarding. You'd be way too rear heavy. So, you'd probably just going to be limited to filling the rear 40-60% depending on if you can get a person or two to sit in the bow.

You will be able to fill that one side full plus the bow sac mostly or completely full for surfing. You'll have to play with how much to fill the front.

Get used to that for a while. If you want to go bigger then get this to put inside your ski locker:

That weight towards the front will allow you to add more to the rear sacs for wakeboarding. You still will likely not be able to fill them completely. Also, at this point (Possibly even before this point) you'll need to start considering a new prop since your takeoff speed will start to suffer.

Then you'll need to buy this (OJ 722 14.75 X 15.5 LC 1 1/8" 4-blade):

Also, at some point you may want something like this Fat Brick to be able to adjust for people weight or just to stick up in the nose of the boat when nobody wants to sit up there:

Somewhere during that evolution you're probably going to decide you either need to plumb in this stuff or get another portable pump because you're spending 30+ minutes setting up and 30+ minutes breaking it down every time you take the boat out. It's not cheap to buy all of the pumps, hose, fittings, switches and wiring and takes a lot of time. It also takes a lot of balls to drill a bunch of holes in the bottom of the hull for intake and the sides of the hull for overflow/drain. I don't have a firm number documented on what it took me.

As you can see you can spend quite a bit of money here.

Also, if you're hard core and don't care if you have ballast taking up seating area then just buy this instead of the Integrated Bow Sac that I recommended in my previous post:

With that you'll be able to fill the rear sacs up more for wakeboarding right off the bat.

If you don't have a filler cushion for the bow you'll have to make or buy one to support that bag sitting in the whole bow. You'll probably want a second pump too because it will take quite a while to fill a single 1,000 lb sac, let alone 3 of them.
