NEW 2021 Mondo surf problems

Prop doesn’t effect wave assuming you can move the weight at the speed you want.

You do have to take Roberts videos for what they are, he knows a wave better than most and usually his proof is when he surfs a wave. It requires good push.

Can you surf a mondo stock with light crew? Not positive, my 2018 SA would but I wouldn’t say it was awesome. 500# lead with a light crew was the difference of good and amazing.

500# and heavy crew.......insane goodness.

Displacement makes exponential improvement.

Waves shut off like a light switch in under 12 feet water as mentioned.

11-12 deg pitch is killing you on a SC boat, they like 8-9.5 pitch. There is no arguing it, other brand boats live at 12.5 deg, moomba/Supras don’t. Robert was pretty clear the mondo needs bow weight to get under 9.5.

Don’t add wake plate, it also kills wave and push. Keep wake plate under 25 max, but hit your pitch number first, then roll number and watch the wave turn on.

chuds, no disrespect taken :) ... but larry calls out some good info on it. if ragboy added weight, it'll need weight. he has forgotten more about setting up a boat than most of us will ever remember.

I will second this. We regularly surf a reservoir with a typical depth of 18-20 ft. Wave is just OK. At Lake Powell (depth 200-300 ft) the wave is phenomenal even lightly loaded. As our regular reservoir dropped to 14-16 ft last fall, we were left with a wave that had very little push.

When we did our Demo in October, the wave was very surfable with only 3 people in the boat and no lead. The only thing that comes to mind besides the lake depth, is that the auto wake sensors may need to be recalibrated. Correct me if I'm wrong, but should the message to add more weight to to the now come on only after certain amount of rear ballast was drained? Try setting your amplitude to 80% and see if you still get the message to add weight to the now. I'm supprised your dealer didn't show you how to setup the wave during delivery. Our dealer does it on a lake. I would call them and have someone come out with you before you frustrate yourself.

If Autowake is on, yes it should drain rear ballast to help achieve pitch if it’s too high, but it will also tell you to move people/mass to assist.

Ideally you want to use autowake to teach you where to put mass while keeping ballast full.

Like Robert said, the mondo doesn’t have a lot of forward leverage, so you need a little more mass than normal in the bow, think teeter totter

Think you have the nose too high... I ran into this issue with my stock Kaiyen with only a driver in the boat when first starting out. The wave looks big, but it's all right off the swim platform and lacks push. Autowake had no clue what to do and would just drain ballast everywhere and I got super frustrated.

Turn off auto wake, fill everything up 100%. Use the centerplate to force the nose down by bumping it down 5% to 10% or so. The wave will look smaller from an amplitude standpoint, but it will be longer and surf with more push. Boards make a big difference too, so if you are riding a stock wave you need a fast board.

As everyone said though, you will have fun... start carving and eventually drop the rope. But you will yearn for more. I'm at 700 lbs of lead in my Kaiyen evenly distributed with just my wife and 2 young kids in the boat which seems to be a good balance for us. But every time we have extra passengers, the wave stacks even more. The boat handles chop a million times better with the extra lead, so there are some side benefits of static ballast as well.

Don't get frustrated and just manually play around with settings to find your sweet spot. Good luck!

ok, ill try that my lead comes on Monday. I just got the new prop going to put that on today and maybe I will try to place the 500-pound fat sac I have from my parent's little boat up near the bow to see if that helps while I wait on my lead to come in

as far board go I have a

Liquid Force Primo 4'10
Hyperlite Broad cast 4.8

my girl is 115 pounds and Im 190 maybe these boards are two smalls for me ?

I have an old inland surfer 4-skim. it's a REALLY small board at 4.4. I'm 215 and can ride it for days and my sis' ex at 250 can ride it as well. it's not the "ideal" size for me but scored it for 100bux back in 2008 and we still take it out almost every time for some fun. it's a board that with a wave lacking push it'll still ride wireless due to it's size.
those boards above should support you all day long. broadcast is one of the best "boat boards" out there and lots of beginners have started on it. we had the 5.0 back in 07-12 and used it for years with all kinds of weights..

Put this 500 fat sac in the bow and it really helped some. my wife could drop the rope but I could not get it. Didn’t seem like any push. But I’m new. Got a new prop on there and the boat runs good I guess I just really need weight to surf on this thing because it’s just us most of the time. And she only weighs 115 so I’m basically surfing a empty boat.

After the 500# sac, what was your pitch?

I could get it to 9.5 and achieve auto wake but I had to run the smart plate to like 77-80. I have 300lb of lead that just cam so I was going to put that in there and try. I have some videos. Im just trying to get them uploaded so you all can see
