Have a 2015 SV233...Need Help

[jkscarborough 4]

I have a 2015 SV233.  We bought it in the fall of 2017.  This is our first surf boat, so newbies.

We are still figuring things out and could use a little help.  We have almost everything on it. Quick surf, all ballast, and CATS.  It does not have ramfill.  I just ordered 500 lbs of lead.

Most of the time it is just me, my daughter, and my son going out and he surfs most of the time.  We all surf regular.  We very seldom have a goofy rider (but would like a good set up for goofy).  He is small, about 125 lbs, and pretty good.  He can handle any wave but loves lots of push (wave snob).  My daughter is small also so they can surf behind just about anything.

I am having trouble when I surf when it is just he and I.  I can't seem to get the push and it is like I have to stay right behind the boat or I go out the back of the wave.  This weekend we were out there with more people and I was able to do better when I got a couple of larger people in the back.

Some settings for each of us would be greatly appreciated!

Thanks in advance!

Fill the QF on both sides.You need to fill the starboard side one before you start filling the fat sacs on the port side to keep the intake low in the water. Also fill the port pro and port pnp. We have 200#’s of lead jammed in the back port corner behind the pnp sac.

Wake plate at 0 and CATS at 100 going 11.2 mph should be a good starting place. Ours is a 2014 SV244 but should be pretty much the same as yours.

The QF valves tend to seize up over time so what I do is open the starboard side first and check the vent hole under the gas cap to make sure air is being pushed out of the tank. If it’s not I stop and start it until it’s filling. Then I do the same on the port side. Then fill the fat sacs

So you do not set it up as a profile to do it automatically?

Anything on the quick surf?

Thanks again!

No, I manually do it every time out.

For 2015/2016 years, listing the boat makes a better wave than using the QuickSurf plates. 2015 was the 1st year for Quicksurf on Centurion boats and unfortunately, the factory plate design was not great at that time. The QS tabs are too small and do not have fins under the tab to direct the water coming off bottom of the boat toward the surf wave, decreasing potential push. The SV boats will put out spectacular wave tho if set up right. You said you have all available ballast bags, correct? If so, assuming you have the horseshoe bag under front seats, 2 large bags in each rear transom and 2) bags mid-ship/cabin, 1 under each seat on sides of the boat (these are called the "pro bags")....is this all correct? Then once you get the 500lbs of lead, depending on which below option you go with will determine where you will want the lead placed. More weight at the front of the boat will make the wave longer, more weight at back of boat will make the wave taller, but also shorter. This gives you maximum push but gives you less real estate to fall back on the wave. I personally use 300lbs of lead under bow filler cushion and the other 200lbs in the cabin next to or just behind the driver as this makes my wave nice and long, yet still plenty tall. I typically run my center trim tab at 30% with how I have my boat setup.

The 3 options to get a better wave IMO (without using the factory QuickSurf tabs) are:

1).  List the boat over to the surf side like Dreamer mentioned above and do NOT deploy the factory QuickSurf plates..... Do this by filling all ballast EXCEPT the back transom PnP bag on the non-surf side, (I am guessing your transom bags are roughly 1,100lbs each since you do not have Ramfill....do they fill the entire locker when full?), you will still fill the Quickfill tanks on both sides 100%, (these hold 500lbs on each side). Listing the boat will net a great wave with better push like you are looking for. (when listing the boat, using CATS does make a difference as it helps to crab the boat and give you maximum wave curl/push).

2). Buy a suck gate like the Nauticurl. ( https://nauticurl.com/ ) I used a Nauticurl on my boat for 2 summers with great results....with this option you fill ALL ballast 100% except only filling the 500lb QuickFill tank on the non-surf side to half just to get a slight list to the surf side since in my experience, it enhances the wave a little having a slight list when using the Nauticurl.

3).  Buy InfinityWave surf tab plates so you can replace the factory QS tabs.....(this is the option I would personally choose since you currently have the factory system and these new surf tabs will net you the best overall wave that is the easiest to set up/use in my experience).......with this option you have everything needed already from the factory (wiring, actuators, etc) so you would just remove the factory QS plates, patch the holes in the transom and then install the new InfinityWave SV surf tabs (the SV tabs have a notch in them for the swim platform bump out). Re-use/re-attach the actuators you already have installed from the factory which will allow you to then use your computer to operate the surf tabs as if they are factory. On my boat, I only need between 8-10 degree's of tab deployment for the best wave.

The main difference between the 2 surf plate designs is that the InfinityWave plates are larger and also have fins on the bottom of the surf tabs which directs the water coming off the bottom of the boat hull at the surf wave....this creates the extra push you want and makes a big difference in the wave your boat will produce. I installed the InfinityWave surf tabs on my 2014 SV244 this Spring and have an awesome wave. A full InfinityWave surf tab kit including actuators, wiring and tabs for an SV is currently $2300....since you only need the surf tabs and not actuators or any of the wiring in the full kit, I am sure that @Shaka would make you a great deal to buy ONLY the 2) surf tabs and the hardware you would need to install them.

With just you and your son, the 500lbs of lead you ordered will also help you with better wave no matter which direction you go since there is no replacement for displacement.

I attached a few pictures of the InfinityWave surf tabs on my boat so you can compare them to the factory tabs you currently have. I replied to you PM, feel free to contact me anytime. If you are near NC, you are welcome to come surf with me anytime!

Wow!!!  Thanks for all of the help.  Can't wait to get to the lake and try these out!

We have 7 ballast in total.  We have (screen pic below):

- QFP and QFS

- P Pro and S Pro

- Bow

- P PNP and S PNP

I had watched a video on how to set up the RI and figured it was all the same.  Boy was I wrong.  : )  I have been filling up all bags except the bow to 100%, the non surf tab to 80%, and the center at 0.  Like I said, my son surfs well on it, but he could surf on anything as he is so light and pumps like a madman.

When the transom bags are full they do fill up the whole locker (upper on each side of the engine). 

The regular surf that was left on the boat is shown in the pic.

My dash is different. Try your CATS at 50. Tab at 0. At least 11mph

Cats will surely help... but you don't "need" Cats on that boat and quick surf sucked on the 15s.  Infinitisurf's #1 comment was spot on.  List it, get that rub rail right at the water line, scoop 100-300 lbs of lead wake and tuck it under the back bags.
