Fenn XT-S

Refined version of the original XT hull, marginally wider (49cm vs 48cm) with revised rocker and volume distribution for improved secondary stability and downwind manners; Fenn describes it as having 'the response and feel of elite-level skis while offering a very stable platform.'

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

Fennkayaks.com specs (490mm width, 5800mm length, sub-11kg vacuum/carbon builds) plus surfski.info's Feb 2019 review calling it 'exceptionally stable' while gliding easily and behaving 'agile and predictable' - sits just below the original XT on stability but ahead on speed.

Speed here also has a traced hull behind it: measured off this boat's own side and plan photographs, the shape alone rates it 6.8, and the published score moves a third of the way toward that. What that means.

Suits: Flat water to solid downwind swell; used for club races, Miller's Run-style downwind days, and as a step-up training ski before an elite hull.

Paddler weight

This hull is built around a paddler of about 87 kg. It stays workable from 76 kg to 92 kg, and sits at its best between 81 kg and 88 kg.

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

Generations

2018-present ('Fenn Mako XT S' / current 'Fennix XTS')

Direct update of the original XT; current Fenn website lists it as 'Fennix XTS,' body copy still calls it 'XT S.' Sits between the Blue-Fin S and Swordfish S in the current lineup.

What works, and what it costs you

What works

  • Genuine step up in speed/glide over the original XT while keeping strong stability
  • Excellent downwind manners
  • Light for the category (10.5-11kg Carbon/Hybrid Vacuum)
  • Actively sold new by Australian dealers (Paddleshop, Oceanpaddler) - easy parts/warranty support

Trade-offs

  • Noticeably less stable than the Blue-Fin S if coming straight from flat water/kayaking
  • Some reviewers note steering felt sluggish until a bigger rudder was fitted
  • Priced above beginner-tier skis, competing with Epic V7/V8 and Stellar SEI
