NSS Confusion

[thejean]

Ok, so I'll admit I'm confused on the NSS settings. My buddy tells me 5 is steep and 0 is mellow. However, an interview by Drew Danielo states that 0 is steepest due to NSS being most deployed:

Then this video says 5 is most aggressive, which seems to match the Nautique literature:

And:

My dealer also says 0 is steepest and most people seem to run 0 NSS and 5 NCRS.

I don't have my boat yet to test myself but I'm really curious as to why there is so much confusion, even between people who should know these boats inside and out. What gives?

[Kenv]

Yep......0 on NSS is "biggest" or most aggressive setting. Tab all the way out on opposite side of the boat. Also NCRS on 5 is either all the way up or down...not sure which...but IN GENERAL NSS at 0 and NCRS at 5 is the most popular starting point on any G

[Wayward]

0 is fully deployed and the steepest setting.

although I found that changing below 3-4 just dirties the wave. If you want to change the steepness I'd lower the NCRS. If I want a mellower wave, I run NSS at 0 still, and NCRS at 2-3, and 11.6-11.8mph. If I have a big crew I run 12.0.

"0" on the NSS means the tab is out the furthest. This delays the water convergence behind the boat the furthest producing a more mellow wave. "5" on the NSS the tab is further in allowing the water behind the boat to converge sooner causing a steeper wave. NCRS works the same way.... 0 is full down which keeps the back of the boat riding higher causing the wave to be shorter in height, 5 is full up allowing the back of the boat to ride deeper causing a taller wave. 0 = Mellow, 5 = Steeper

Which model of boat ?

210 runs 2 most of the time

Ok so we now have established that NSS of 0 means tabs are all the way out. But wayward seems to believe that means steepest and F725 seems to believe more mellow wave, implying not as steep. Both of whom strike me as very knowledge and credible sources of info on this board I might add...

The literature from Nautique (and the video) clearly states that NSS of 5 is steepest (as per F725).

So does NSS of 0 then mean more mellow but longer (but not as tall and not as steep)? Perhaps the Nautiques react to the NSS differently because they ride so flat and thus engage more of the front hull with NSS fully deployed?

I'm also of the opinion that tabs all the way out would also force the opposite side further in the water, thus creating a taller steeper wave but also agree with F725 that it would prolong convergence. Anyway, I'm still confused. Does anyone have pics at both 0 and 5 with everything else being equal?

Lucky7t, I don't think it matters which boat as I think the relative effect should be the same on all Nautiques with NSS, no?

Maybe the G23 acts totally opposite from the others due to the shape of the transom. I know it slopes back towards the bow which I could see would help drive the back of the boat deeper in the water also causing a steeper wave the more the NSS is extended?

I'm speaking from experience on from our 2012 thru 2017 210's with NSS and also from our 2015 G21 with NSS. On the G21 and the 210's, NSS does not make the boat ride any deeper in the water. NCRS or Hydrogate will change how deep the back of the boat rides in the water which will effect wave height.

Again.... maybe the G23 acts different with NSS. I have not spent much time in a G23.

Maybe we are both right!

[thejean]

Possibly but that pic I posted about the NSS setting was from the G series owner's manual which clearly states that 5 is steepest. Anyway, it's no big deal as I'll play with it myself when I get the boat on the water next summer. I was just curious because I've been reading about surf settings and not knowing which way is which makes it difficult to try to figure out what people are shooting for with their settings.

I second this regardless for what manual says. Could be typo in manual perhaps?

Your correct but makes a huge difference in wave with the additional ncrs .

But like others have said 0= tall and short, 1 = not as tall and longer and so on.

Here Adam does reference 5 being the steepest and 0 being the most mellow. He does however mention that the NSS will cause the transom to sink lower when deployed further toward 5.

I can say on the 2017 230, this is absolutely the case. All of us pretty much insist on taking the Pebble with us when we surf. I can confirm that NSS 0 is plate FULLY extended. You can see it when you're surfing. I can also confirm that 0 produces the longest wake. 1 is a bit taller, but not as long. I don't go past 3 because it gets too steep for me.

Ok so we have two votes for 0 is mellow and 3 votes for 0 is steep. Maybe I should start a poll? Lol

Well I think the best thing to do is first establish if the behavior of the NSS is the same on all of the boats. I can tell you for sure on the 230, Zero=fully extended. As you move up on the NSS, the plate slides in. I know this because I can easily see it when I'm surfing. This is NOT the case on my neighbor's G23. To be fair, he has a 2013 (first year of the G23) and the NSS was added to the boat in 2014. Perhaps this is why I can't see the plates when I'm surfing behind his boat.
