## 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 75–88 kg, broader estimated guide 61–91 kg. An estimate from hull dimensions, not the designer's intended weight.

## Suits
Elite flatwater racing and downwind in the hands of an advanced/elite paddler; calm-to-open water.

## Hull
Narrow 42cm legacy elite hull on a 6.45m length, in the width band of the Epic V14 and Think Uno. Tippy, low-volume race shape for flatwater and downwind specialists; superseded in Sipre's line by the Ackua Veloce.

## What works
- Very fast, narrow 42cm elite hull
- Light composite/carbon builds (~11.5kg)
- Legacy Portuguese race pedigree

## Trade-offs
- Discontinued, parts and support scarce
- Tippy, elite-only stability
- Secondary market only, rare outside Portugal

## Generations
- ~2010-2013 (discontinued): Legacy narrow elite race ski (42cm x 645cm) with a wider 'Sea Vortex +' 44cm x 642cm variant; dropped from Sipre's catalogue and superseded by the Ackua Veloce line.

## What paddlers say
- The surfski.info Width x Length chart lists 'Sipre Sea Vortex' at 42cm x 645cm and a 'Sea Vortex +' at 44cm x 642cm among the narrowest elite-width skis; the model no longer appears in Sipre's current catalogue (surfski.info).
