## Ratings (Surfski Index estimates)
- Stability band 6–9 out of 10 (editorial estimate, low confidence).
- Speed rated 7 out of 10.

Our estimate from published descriptions and reviews. 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 a cautious editorial estimate; it is not backed by a hull trace. Qualitative context includes 2 linked sources.

## Paddler weight
Estimated sweet spot 81–94 kg per seat, broader estimated guide 66–98 kg. An estimate from hull dimensions, not the designer's intended weight.

## Suits
Surf lifesaving double-ski racing and surf-zone paddling for two. Built to the class weight of at least 32 kg, so it is a two-person carry.

## Hull
Two-seat surf lifesaving specification ski, hand-built to order in Warriewood, NSW. BOS publishes no dimensions or weight: the figures shown are the SLSA double-ski class limits (7.32 m maximum length, 58 cm minimum beam), and the class sets a 32 kg minimum weight.

## What works
- Custom built for both paddlers, with fixed or adjustable footwells and a deep-seat option
- Same tail-rocker hull concept as the single, for control through the break

## Trade-offs
- No published length, beam or weight
- Built to order: about 12 weeks plus freight

## Generations
- current: Listed by BOS as the Nemesis 3 Double, the two-seat version of the Nemesis. Fixed-length or adjustable, standard or deep seat.
