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. How we rate.

Stability here means how steady the ski feels sitting still on flat water. Where two craft have overlapping ranges, we can't say which is more stable. Downwind handling is a separate thing, covered in the evidence note below.

Evidence note

This band is estimated from published dimensions. Qualitative context includes 1 paddler report and 2 linked sources.

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

Paddler weight

The estimated sweet spot is 75–88 kg, with a broader estimated guide of 61–91 kg. This estimate is a guide, not a limit. Seat fit, conditions and paddling style matter. Lighter paddlers can still enjoy a larger hull, especially downwind. A test paddle is the best check.

Estimated from hull dimensions using a formula fitted to makers’ own paddler limits. It does not establish the designer’s intended paddler weight. How this is worked out.
