## Ratings (Surfski Index estimates)
- Stability band 6–8 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 3 linked sources.

## Paddler weight
Carbonology rates this hull for paddlers from 50 kg to 125 kg per seat.

## Suits
Ocean racing and downwind for a competent crew who want a fast double without committing to the 46 cm Flash X.

## Hull
A 7.25 m x 50 cm double on a 38 cm deck, two centimetres narrower and slightly longer than the Boost X double. Buckets are 42.5 cm wide and 20 cm deep. The ergonomic changes over the Boost double are aimed at letting a crew hold technique and run waves rather than simply stay upright.

## What works
- Real step up in speed over the Boost X double for [price omitted] more at the base layup
- Deeper layup ladder than the other doubles, down to 16 kg
- Still forgiving enough for a mixed-ability crew who can brace

## Trade-offs
- 7.25 m and 50 cm asks more of the back crew than the Boost double
- Longest hull in the range to store and transport
- No published review or owner report

## Generations
- 2023-: The intermediate double in the X range, introduced alongside the Cruze X RT and Flash X LV as one of the "new arrivals" in the 2023 catalogue.
