## Specifications
- Length: 6.45 m
- Beam: 43 cm
- Deck height: 33.5 cm (estimated)
- Usually paddled by: Racers

## 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 3 linked sources.

## Paddler weight
Estimated sweet spot 78–91 kg, broader estimated guide 63–94 kg. An estimate from hull dimensions, not the designer's intended weight.

## Suits
Ocean racing and downwind for an experienced paddler.

## Hull
6.45m x 43cm elite hull, the fastest thing Opium builds and the one Brazilian racers take to open-water events.

## What works
- Elite footprint from a maker with local support in Brazil
- Range deep enough to move up through
- Long waterline for the beam

## Trade-offs
- No published weight or layup table
- No price published anywhere
- Effectively unavailable outside South America

## Generations
- current: Opium Caiaques is a Brazilian builder with the widest ski range in South America: seven surfskis from an elite 6.45m racer down to a 5.25m beginner hull, alongside OC1, OC2 and OC6 outriggers. Opium publishes an overall hull height for each boat; that figure is not the deck height this index uses for weight bands, so it is not carried across.

## What paddlers say
- No independent owner review located as of August 2026.
