What does a D cut do?

Buddy asked me this today, and while I know I prefer the effects of a d cut plate, I didn't know how to properly answer the question.

So here I am, asking ya'll.

it lifts the nose and squats the rear. This is debatable but I think it makes the ski carve better because the rear is dug in more.
 
rides with nose higher... slightly less likely to pearl...backend slides out easier when sliding on the face of a wave...you can also jump the ski straight up easier...imo

Think opposite of an extended ride plate. I feel like you can give more input to the steering, much like the setback pumps and of new aftermarket hulls, only a free option!

IMO: The D-cut mod is "over-rated" when it comes to performance....of any kind.

It severely weakens the sj stock plate..(mine lasted a few rides)

Never noticed improvement with a d-cut.

Currently run with a worx dominator cut off to stock length. (it has a "d-hole" in it)

This is all opinion. Factors such as your body weight etc... can change things.

dcut works 100%..it allows the ski to slide more predictably/controllably....with a stock plate cut flush i feel like its all or nothing when it slides..

dan u must be doing something wrong when u cut them...ive had the same dcut plate on my ski for 4years...it even survived sliding out the back of my truck the other day with minimal cracking..still running it..

The possibility that I'm doing something wrong is very real!
But I must stick with my initial assesment of the d-cut mod...."all but useless".
(with my set-up etc...)
It seemed to get the nose up a bit when you were cruising/waiting on a wave, but once I got into the throttle a bit, or dropped in, I felt no diff from a stock plate.
Maybe my aggressive intake, maybe my riding style...I don't know. But the d-cut, to me, was a waste of time.
I can slide my ski at will.
I do have an ongoing pearling issue when I'm aggressive with a wave. But My hope is that tubbies will help with that.

A d-cut in the ride plate is like a pimple on a mountain. The planing affects of the hull are still there. A coffee-can sized half circle in an area where the water is already greatly disturbed has little affect above idle speed.
Shortening the hull, I would imagine, would actually give the desired affect.

I swore by it on my 750 and SJ but when I rode a friends SJ with a d cut rideplate, I asked him when he was going to put that d cut rideplate on. Granted I don't ride my friends ski's as much as mine so that's not a fair comparison but I think the d cut in conjunction with shortening the hull makes a massive improvement.

IMO, for us lighter guys, it's makes all the difference. The ski will ride similar to how it did before but you have the ability to push the back end of the ski down easier in preparation for a jump so you'll go a little higher. I found the ski was more predictable but all rider preference since most people can't ride my ski's comfortably.

The d-cut is a B/S mod that's been in place for a long time....and has produced squat in performance.
People think they need it because everyone else has it.
BS. Especially in surf..

All I can say is ....find a stock plate...cut it...ride..
and be honest with yourself.

I can honestly say that after I broke my stock d-cut stoke plate I put on a wammer plate that I cut flush. every time I slashed a wave the ski came out from under me. After I D cut my wammer plate my ski had the sliding control I was used to.

I D cut the protec extended ride plate on my SN
and really liked the difference
but every one and ski is different
 
I disagree Dan that it's a BS mod it makes a significant difference in the nose riding height and ease of sliding...the ski jumps for the moon off boat wake too straight up if you desire...I do think it takes more effort to get

So you're saying that the d-cut helped you "grab" rather than slide?

I can belieive this.

But the point/purpose of the d-cut is not there.

Let me say again: This mod depends upon your body weight, motor/hull set up etc..
waste of time for the average rider.

I think you are wrong, there is a huge difference...

I have two skis that are set up exactly the same, exept one has an extended stock rid plate, and the other has an entended wamiltons ride plate that is d-cut. The extended stock ride plate keeps the nose of the ski down at all speeds, where as the d-cut keeps the nose up high at low-med speeds, and has the planing characteristics of a long ride plate at med-high speeds.

Personally since I am a bigger rider, I don't like the d-cut as I have no problems keeping the nose up at low speeds...

Cheers..

***EDIT***
Dan, I just saw you last post and I agree the d-cut works better for larger riders, but the average rider still gets a handling advantage from it.

It is just a waste of time for you and your riding abilities
