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.
