## Specifications
- Length: 6.4 m
- Beam: 42.8 cm
- Deck height: 33.5 cm (estimated)
- Usually paddled by: Confident ocean paddlers

## 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 4 linked sources.

## Paddler weight
Estimated sweet spot 77–89 kg, broader estimated guide 63–93 kg. An estimate from hull dimensions, not the designer's intended weight.

## Suits
Long-distance ocean racing and Western Australian downwind, which is where the boats were developed and raced.

## Hull
6.4m x 42.8cm long-distance race hull, the standard of Oceanbuilt's two skis on the same footprint.

## What works
- Race beam from a designer with serious offshore yacht credentials
- Built and tested in Western Australian downwind
- Long waterline for distance racing

## Trade-offs
- Almost no published specification beyond dimensions
- No public price
- Distribution is Western Australia and little else

## Generations
- 2013-present: Western Australian maker whose lead surfski designer, Britton Ward, is a naval architect from the Volvo Ocean Race and America's Cup side of the sport. Both long-distance skis share a 6.4m x 42.8cm footprint.

## What paddlers say
- Raced in The Doctor, the Western Australian downwind classic, which is the conditions the hulls were built around.
