There's no such thing as "full camber" i.e. camber on the "whole length" of a cambered ski. Camber ceases where the tips and tails start turning up however little they may ultimately turn. Bending the ski tips and tails upwards is the opposite of camber. A rocker-camber-rocker ski has camber over the RUNNING LENGTH of the ski. And technically, unless the tail is actually flat, every cambered ski has some rocker‐camber-rocker form.
Yes, excluding classic type tip and tail length... What would be the proper term then? Don’t want to confuse anybody else… :geek:

It's simply a cambered ski. How much rocker and splay are related to how much camber on the running length but not how much camber it may have as a matter of, for want of a better term, vertical camber or what is normally meant by "camber".
How much camber a ski has in the sense of whether it is double camber or single or camber+ and how much effective camber the ski has longitudinally are different things.
Marketing adds layers of confusion (often b.s) to otherwise simple issues. Terms are often unclear at best. There are lots of distinctions with little difference.

Translation then:
By full camber I meant lack of rocker, nothing else. Forget about double camber, I know nothing on that variant of the sport.
Today no rocker already means a more carving oriented ski I think. But i’m not sure if there are many all mountain 100+ waist skis without rocker today, therefore the additional perceived value on my old Coombas. All about my style anyway, not intending to generalize.

Strictly speaking every ski ever made had/has rocker.
Again, the terms is, frankly, abused.
You can speak of the a ski with NEGATIVE camber as being fully rockered since it has inverted camber(i.e. it has no camber in the normal direction ) but saying a ski with 0 camber (flat on the running line) has 0 rocker makes no sense and neither does saying a rocker-camber-rocker ski has no rocker, obviously.
Some use "rockered" to mean fully rockered but they never bother to make it clear. It makes sense to speak of fully rockered skis but not fully cambered skis being that no ski of any use is cambered from tip to tail and a "fully rockered" ski is FULLY inversely cambered tip-to-tail.

The expression "ski with no rocker" is an oxymoron, unless you are using the term specifically to refer to skis shaped like the rockers on grandpa's favorite rocking chair.
You Coombas have some rocker.. Imagine you could bend camber out of those Coombas by pulling the tips and tails upwards and inward. Gradually you would be adding more and more rocker to those skis ..until eventually they would be FULLY rockered and the camber would be inverted.

Also, supposing you have a great carving ski, adding more camber or inverting that camber will most likely negatively impact the carving ability. In both cases, you would be decreasing the running length while making it harder to set and hold an edge. In any case, some rocker obviously does not mean no rocker.

The original punk rocker in my neighborhood growing up would ride around on his skateboard sporting an electric guitar with a transistor radio as an amp. That board had some rocker, lol.

It’s a generational thing.

All skis have rocker. But rocker didn’t become ”a thing” for companies to push until freestyle or twin tip skis. With such skis, rocker isn’t a technical issue. It’s a major promotional feature.

So a younger skier wouldn’t call an older ski a “rocker ski”. An older skier might find such a dismissal absurd tho. Different perspectives… like if people were talking about “wide skis” without a defined reference point.

My guess is @Andinista is much younger that @MonomarkMark, which would explain their different perspectives on what constitutes a rocketed ski and what doesn’t.

It's not just perspective, it's also an issue of using terms unclearly or using a term in multiple conflicting ways.
If fully rockered skis are the only skis rockered, then there's no such thing as a rocker-camber-rocker ski. Rocker is a matter of degree. Skis are either fully rockered or not. And marketing, as always, is to blame for some of the confusion.
And twin tipped skis are indeed rockered with more tail rocker generally than rocker-camber-rocker types but, again that tells you nothing about the camber of any particular twin tip.
There's any easy way to clear out the confusion: if you mean a ski is FULLY rockered, then just say so. But no matter how you approach the mayhem, there's simply no such thing as "fully cambered" ski or a ski without at least some tip rocker.

Yeah, full rockered is misinterpreted too. Are we talking twin tip or twin tip reverse camber? It’s easy to get confused… and yeah, marketing ppl say all kinds of things that make their way into the common lexicon.

In 20 years from now, when an older skier is off the slopes, which usage will prevail? Betcha it will be what younger skiers are using today. Can’t fight that… so maybe easier to just ask if they mean twin tip. If they reply “yes” you’ll gain a common understanding plus it will give you a hint that they might be a younger (though not necessarily less capable) skier.

Another paper worth reading…

Almost worth putting this into the forum Knowledge Base…
