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

Fennkayaks.com specs (530mm width, 5780mm length) place it as the widest current-production single; surfski.info 2024 forum note says the Fennix version 'isn't very different to the earlier model, still a very stable, very easy to use ski,' with a small speed bump from the 'S' update.

Suits: Flat water and moderate ocean chop/swell; good first ocean ski before stepping up to an intermediate hull.

Paddler weight

This hull is built around a paddler of about 101 kg. It stays workable from 89 kg to 107 kg, and sits at its best between 94 kg and 103 kg.

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

Generations

2016-present

Updated 'S' hull revision of the original Bluefin; now sold simply as the 'Blue Fin' under Fenn's current Fennix branding, tagged Beginner on fennkayaks.com.

What works, and what it costs you

What works

  • Best-in-range stability, easy to remount
  • Good resale value per surfski.info forum consensus
  • Light enough (10.5-11.5kg) for easy car-topping/beach carry
  • Loves catching and linking small waves

Trade-offs

  • Still the slowest current Fenn on flat water/racing
  • Beginners will likely outgrow it within 1-2 racing seasons
