Think Duo S

Compact double-ski, same length as an Olympic sprint K2; rocker line and volume tuned for a lighter crew (35-75kg per paddler) to reduce windage and maximise waterline, retaining Jet-derived low-volume cockpits at each seat.

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 1 linked source.

Suits: Club/training doubles and downwind runs for lighter/junior crews; not sized for two average-adult men.

Paddler weight

Think rates this hull for paddlers from 35 kg to 72 kg per seat.

Generations

~2021-present

Think's only current double/tandem surfski (no earlier 'Double Shot' variant exists). Reuses the Think Jet's bucket and footwell, scaled to a K2-length double.

Pros and cons

Pros

  • Club-friendly length (same as an ICF K2): easier storage/transport than most doubles
  • Side and end carry handles for two-person handling
  • Quick-adjust footboard, Jet-proven ergonomics for smaller paddlers
  • Good stepping stone for junior/lightweight crews into double-ski downwind paddling

Cons

  • Combined-crew weight ceiling (~70-145kg total) rules out two average adult men
  • No independent weight/layup/price data published: hard to buy sight-unseen
  • Thin secondhand market

What paddlers say

No independent paddler reviews found on surfski.info, SurfSkiRacing.com or forums as of Jul 2026: too new/low-volume for community write-ups yet.Reported experience
