## Specifications

## Ratings (Surfski Index estimates)
- Stability band 4–6 out of 10 (dimension estimate, low confidence).
- Speed rated 9 out of 10.

Modelled from published beam, length and deck height. Low confidence. Speed is our rating. Both are given at the hull's own design weight.

These ratings are Surfski Index estimates, worked out from published dimensions, traced hull shapes where we have them, and reviews. They are not supplied by the maker or timed on the water. How a ski feels depends on your weight, skill, set-up and the conditions, so use them to shortlist skis and paddle one before you buy. Method: https://surfskiindex.com/how-it-works/#limits

Evidence note: This band is estimated from published dimensions. Qualitative context includes 2 paddler reports and 4 linked sources.

## Paddler weight
Think rates this hull for paddlers from 50 kg to 90 kg.

## Suits
Flat-water time trials and downwind for light, experienced racers (50-90kg). Not a boat to learn on.

## Hull
Narrow, low-deck elite race hull built for lightweight paddlers (50-90kg). Same 43cm beam as the Uno Max but less volume/freeboard, so noticeably less forgiving; low windage deck.

## What works
- Very fast for its weight class
- Excellent ergonomics/fit reported by owners
- Low windage deck

## Trade-offs
- Extremely tippy, even among multi-ski paddlers
- Narrow 50-90kg paddler window
- Ultimate layup special order only

## Generations
- ~2011-2022 (Gen1/Gen2): Predecessor to the current Uno; composite race ski built for lightweight elite paddlers.
- Gen3, current: Lower leg hump improves leg drive for shorter-legged paddlers; reduced deck height cuts windage. Validated by World Champion Teneale Hatton.

## What paddlers say
- wesley (surfski.info): 'the most unstable ski I paddled outside my [K1]... it did not stop me though because it was fast and I loved the fit.'
- Stew, Think Kayak Australia (surfski.info): at 77kg found himself 'on the very lower limit' for the Max and kept returning to it over the Uno despite loving the Uno's fit.
