## 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
SeaBird rates this hull for paddlers from 70 kg to 90 kg.

## Suits
Ocean racing, downwind and flat-water time trials for an experienced paddler.

## Hull
6.4m x 43.5cm full-length racing hull, the one SeaBird calls an all-out no-compromise ski for any condition. The maker still claims it is a little more forgiving than comparable skis and talks about efficient speed rather than top speed, which is the same argument the rest of the range makes.

## What works
- Elite footprint from a Nordic maker with dealer support in Europe
- Three layups published with real weights
- Recommended paddler weight stated by the maker

## Trade-offs
- 19-21kg is heavy for a modern elite ski
- Out of stock across the range when checked
- No published price

## Generations
- current: SeaBird Designs is a Norwegian design house whose composite boats are built and shipped by Ceranos Invest OÜ in Estonia. The surfski range is three Wave models on one design language, and the smallest of them is a Björn Thomasson design.

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