Description
The C1 is Connelly’s top-of-the-range slalom ski, handmade in the brand’s own factory in Washington State. With a 90% carbon laminate and a wider tip and tunnel, it is designed for running the buoys on a competition lake.
Who is it for?
For expert slalom skiers and competitors who tune their ski to the millimetre.
What sets it apart
Its VersaFin fin adjusts for depth, forwards and backwards by screw, without forcing the fin into place. Its five Versatail heel blocks (VT, VS, VR, VRS and VSR) change how the tail releases from the water. It comes in five lengths, from 63 to 68″.

Technology
The Connelly profile
Versatail tail blocks
Versatail is Connelly’s interchangeable tail system (patent pending). Each block changes the geometry of the back of the ski and the way water leaves it: one more adjustment, beyond the fin and binding placement.

VT, stock tail
A balanced tail depth through the turn and across the wake.

VS, square tail
A square tail that lifts the ski more and releases water cleanly, for speed.

VR, round tail
The ski stays deeper in the water as it enters the turn: more control at high speed, shorter turns, less tail slide.

VRS, round to square
The ski sits deeper in left-hand turns and puts more weight on the tip in right-hand turns: a way to balance your strong side and your weak side, to suit your strength and style.

VSR, square to round
The same principle as the VRS, mirrored: an asymmetric tail to balance the ski between turns on your strong side and those on your weak side.

VT+, extension
An extension that takes the ski from 63″ to 65″.
Supplied with the ski: VT, VS, VR, VRS and VSR on the 65, 66, 67 and 68″; VT, VS, VR and the VT+ extension on the 63″.
VersaFin
Patent pending. The fin adjusts up, down, forward and back through threaded mechanisms: precise, accurate adjustment, without having to force the fin into place.

Depth
With the two wheels, which raise or lower the fin directly.
Distance from tail (DFT)
With an Allen key, straight forward or back, without tapping the fin.

Laminates: carbon or fibreglass
Performance skis use carbon for precision and explosive acceleration; recreational skis use fibreglass for a forgiving, less demanding ride. The blend of the two tunes the flex of each ski to its use.
On this modelCarbon 90/10
Carbon is very light and very responsive. 10% fibreglass damps vibration: chop is smoothed out, and the ski lasts noticeably longer.
Compare with the others: Carbon 50/50, Fibreglass

Carbon 50/50
As much carbon as fibreglass: a fast, responsive ski with a smooth, consistent flex that does not chatter on less than perfect water.

Fibreglass
A technique known since the 1960s; advances in fabrics and how they are layered now give light skis with a consistent flex that damp vibration well.
Under the ski
On this modelV-Tech
Six V-shaped steps break up the flow of water under the ski, from the front binding to the fin. Less water clings to the ski as it accelerates: it turns more easily and drags less.
Compare with the others: Speed V-Tech, Connelly Tracking System (C.T.S.)

Speed V-Tech
V-Tech adapted for fast skis: the curved V steps slow the water in the middle of the tunnel more than along the edges. Drag drops without losing edge grip.

Connelly Tracking System (C.T.S.)
A slight rib under the tip keeps the ski running straight while the boat pulls you out of the water on a deep-water start.
Binding placement
It is measured from the tail of the ski to the heel of the front binding.
