sluggish Big Mountain skis are getting popular with elephant youngsters
- an attempt of liberation.
First of all you must have weapons and tools that are at least as good as conventional ones.
Let’s try it with guns like this:

We dared to fix metal fins at ski tail such creating an efficient direction and speed control.
You immediately feel an unusual grip of metal fins when skiing off-piste.
Twisting the feet left or right makes skis pivot on their fins and draw a clean curve in the snow.
Merely on hard snow surface you have to care that fins do really carve and occasionally „shoot“ feet and skis forward to put a pressure on fins and to execute a powerful „jet turn on the fins“.
Otherwise you are free to turn as you are used to (carve and skidded turns on ski edges).
The location of fins behind ski boots produces momentum that
forces both skis to automatically stabilize in the driving direction and therefore parallel to each other. Unlike shaped carver this ski offers no handle
at ski tip section to get skewed by bumpy terrain.
The ski above has streamlined fins for high speed in soft snow.
Models for hard snow favor short upright edge of the front fins.
Extremely short ski tail allows smooth turns „on the fins“ in very steep terrain.
Models with large fins under your feet are good for crossing corn fields as steep as 70 degrees.

Tom is an example of such great thinking!
Would love to test such "ski"!!!!
First idea that comes to mind is in deep powder what happens to tails! I suspect you get that sinking feeling!
I ski on a pair of Sugar Daddys when I have chest high powder and I can feel them floating on powder! With no tails..I wonder!!!!
Do they also catch hidden Leeks
?

Pavel, do you mean a kind of helpless sinking backwards and touching the snow with your neck?
Well the more upright the ski stands on its tail the stronger the pressure of snow on the tail
which in turn produces a torsional moment lifting the tail from the snow.
This is the miracle perceived by every novice on very short ski with sharp tail edge like
„Firngleiter“ or „Big Foot“: he/she is running fast over bumps and is wondering why he/she
is still standing.
Generally, short ski (with or without fins) can surf on deep powder like a water ski,
provided the ski is fast enough or the slope is steep enough.
Of course, never try to stop in flat deep powder with a short ski!
Does your second question mean „ploughing greens with the rear fins“ ?
No problem for streamlined fins, worse for hard-snow models, especially when scratching rock bottom. But the „miracle“ happens again:
When fins have been knocked by a rock under the ski,
ski tail shoots in the height and ski tip dashes against the snow
... and you already passed the rock, you are still standing and not knowing why !!

Thanks, Rossfra8.
Hope you will have opportunity to test them.
Well, any ski is a candidate for the saw.
The thicker the ski corpus (for screws) and the less shaped the ski is, the better.
Take a 190cm ski, move front part of the binding as close to the tip as possible. It could be around 50cm from the tip. Boot is about 32cm,rear part of binding is 10cm. Cut the ski 12cm behind the binding.
The ski corpus is now 104cm.
The front 30cm of the rest will be used as a carrier of the fins. It is to be mounted at an angle of 8 to 16 degrees. The new ski is now 120cm long.
You can design your own fins, the material should be hard aluminium at least 3mm thick, cut with metal saw from a L-profile.
We hope we will have enough skis for testing.

You are a dangerous man! You now have awakened my desire to test this new mode of skiing!
My friends and wife thought I was "strange" when I mounted two ski bindings on one ski! Yes it was strange in the 1970's, now if I had just widened the ski,,,voila I would have had "boards"!
Will contact you for more specific details!
