## Specifications
- Length: 6.25 m
- Beam: 46.35 cm
- Deck height: 33.5 cm (estimated)
- Layup weights: Standard 9.2 kg, Pro 8 kg
- Usually paddled by: Paddlers in chop

## Ratings (Surfski Index estimates)
- Stability band 6–8 out of 10 (dimension estimate, low confidence).
- Speed rated 7 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 5 linked sources.

## Paddler weight
Estimated sweet spot 84–98 kg, broader estimated guide 69–102 kg. An estimate from hull dimensions, not the designer's intended weight.

## Suits
All-round ocean swell, up/downwind and flat water; confidence-inspiring in chop and for remounts.

## Hull
Modified Vega with added width for stability, plumb bow, sharp entry and bold rocker for swell and downwind. Good primary and secondary stability that lets you sit side-saddle easily. Same single-piece prepreg carbon, triple-reinforced center.

## What works
- Excellent primary and secondary stability; easy remounts in sloppy chop
- Punches through waves confidently
- Same fast Vega hull family with a wider, friendlier platform
- Light, stiff carbon build; Pro ~8kg

## Trade-offs
- Slightly slower/less lively at the very top end than the Vega
- Not a boat to win flat-water races on ('don't expect to race with it')
- Premium price, limited AU used stock

## Generations
- 2020-: Kai Bartlett + Mike Giblin. Wider, more stable sibling of the Vega keeping the same DNA; Standard and Pro layups. Maker lists overall length 20 ft 6 in (6.25 m rounded), confirmed against current Flex artwork.

## What paddlers say
- 1,400-mile long-term test: highly stable, versatile everyday ski, minimal drawbacks, but not a racer (thepaddlechannel.com Vega Flex review)
- In-depth vs Fenn Swordfish S: more stable, especially punching waves; comfortable side-saddle and remounts (surfski.info)
