## 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 1 paddler report and 2 linked sources.

## Paddler weight
Estimated sweet spot 77–90 kg, broader estimated guide 63–90 kg. An estimate from hull dimensions, not the designer's intended weight.

## Suits
Advanced/elite racing and ocean downwind.

## Hull
6.40m x 42cm narrow race hull (max paddler ~80kg) built for speed and downwind at the sharp end of the Genius line. Low-volume, rewards balance and technique.

## What works
- Fast, narrow race hull
- Light carbon layup (~12kg)
- Proven SA racing lineage

## Trade-offs
- Low stability for the average paddler
- ~80kg paddler cap
- Limited pricing transparency

## Generations
- ~2018-present: Elite/racer end of the Genius range; SA-built, AU distribution via Charger Surf Craft.

## What paddlers say
- The Genius G40 is listed on the maker's surfski page as the competitive racer of the range; Knysna skis feature in AU paddlers' fleets via Charger Surf Craft distribution.
