## Ratings (Surfski Index estimates)
- Stability band 7–9 out of 10 (dimension estimate, low confidence).
- Speed rated 8 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 4 linked sources.

## Paddler weight
Estimated sweet spot 75–75 kg per seat, broader estimated guide 75–78 kg. An estimate from hull dimensions, not the designer's intended weight.

## Suits
Tandem ocean downwind and touring; a skilled paddler paired with a less-experienced partner

## Hull
Relatively short (6.70m) tandem hull with pronounced rocker / keel-jump for maneuverability and quick response, plus dual steering (front, rear, or both). At 50cm beam it carries stability comparable to a single advanced ski, enough for a strong paddler to bring a less-experienced partner on a downwind. Front cockpit 155-190cm, rear 160-200cm.

## What works
- Very light for a double (CarbonLite ~14kg)
- Short, high-rocker hull is maneuverable and responsive
- Dual steering lets front, rear, or both paddlers control

## Trade-offs
- Higher price than single skis
- Doubles are niche; limited resale market
- Requires a coordinated pair to paddle well downwind

## Generations
- ~2021-present: Nordic's tandem surfski; short-for-a-double 6.70m hull with heavy rocker and dual steering. Nextwave reviewed the first version.

## What paddlers say
- Nextwave review (first version): the NK Double is ~50cm wide with 'stability about equal to the Zest', built so 'a skilled paddler should be able to bring a beginner to experience a downwind', with CarbonLite construction at about 14kg (nextwave.nu).
