Modelled from published beam, length and deck height. Low confidence. Speed is our rating. Both are given at the hull's own design weight. 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 2 paddler reports and 6 linked sources.

Suits: Small surf, shore break play and sheltered water for juniors and light adults up to about 1.78m tall.

Paddler weight

The estimated sweet spot is 48–56 kg, with a broader estimated guide of 39–58 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.

Pros and cons

Pros

Cons

  • Slow on flat water for its length
  • Cramped for larger adults
  • Seat sits well aft, which some owners find awkward on the flat

What paddlers say

surfski.info owner (1.78m, 88kg) who bought one for his children: 'it's got lots of rocker, a big volume bow' and is 'very maneuverable'; he could barely fit and suspected it 'would be relatively slow as a flatwater trainer.'Reported experience
Leif Aterra, Swedish dealer, surfski.info: 'Jester which we also have sold is a more stable boat and slower' than the Carbonology Splash.Reported experience
