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.

Stability

Speed
6.0

Both scores are rated at the hull's own design weight. How these are derived.

51cm beam and doubled hull volume vs the solo Jet give real secondary stability for two; marketed for intermediate paddlers downwind, but light-crew-only sizing caps outright speed vs a full adult double.

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

Paddler weight

This hull is built around a paddler of about 75 kg per seat. It stays workable from 66 kg to 80 kg, and sits at its best between 70 kg and 77 kg.

Derived from published hull dimensions and calibrated against manufacturer paddler limits, not taken from a marketing range. The method, in full.

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.

What works, and what it costs you

What works

  • 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

Trade-offs

  • 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
