Fenn Fennix Spearfish

Full-length, higher-volume advanced ocean hull sitting just above the Swordfish: 6315mm x 455mm, with a wide 407mm seat and a tall 360mm bow height - the most volume forward of any current Fennix single. Balanced rocker for swell and flatwater, a newly designed ergonomic seat, and an extended footwell that dealers single out as the reason it suits taller paddlers. Because it carries elite waterline length on an intermediate beam, the effective gain over a Swordfish is larger than the 20cm length difference suggests for a rider who sits high in the Swordfish.

Modelled from this hull's traced beam and depth at its design weight. Medium 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 based on a trace of this hull’s geometry. Qualitative context includes 5 paddler reports and 5 linked sources.

Speed is also checked against the traced hull. Measured from this boat's side and plan photos, the shape alone rates 8, and the score shown is moved a third of the way toward that. What that means.

Suits: Ocean swell, downwind and flatwater for improving/advanced paddlers; the volume and 407mm seat point at taller and heavier riders, roughly 85kg and up, with the Sailfish covering the same footprint below that.

Paddler weight

The estimated sweet spot is 88–102 kg, with a broader estimated guide of 72–106 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.

Generations

2024-present

Announced on Fenn's Facebook page in late June 2024 alongside the Fennix Cuda. Positioned as 'a longer Ski which helps to bridge the gap between the Fennix SWORDFISH and the ELITE Skis' - roughly elite length on a Swordfish-plus beam. Offered in Hybrid and Carbon only. In late 2025 Fenn added the Fennix Sailfish, which shares the Spearfish's 6.3m x 45cm footprint but drops the seat to 400mm and the bow height from 360mm to 325mm for paddlers under 85kg - which by implication makes the Spearfish the higher-volume of the pair, aimed at the bigger paddler.

Pros and cons

Pros

  • Elite waterline length on a forgiving 45.5cm beam - more speed than a Swordfish without stepping into an elite hull
  • Highest volume and tallest bow of the current Fennix singles, so it suits big and tall paddlers other race skis pinch
  • Extended footwell and 407mm seat are the roomiest in the range
  • Dealer-nominated pathway boat for surf lifesaving paddlers moving into ocean racing

Cons

  • Too lively for beginners despite the intermediate label
  • Hybrid/Carbon only - no cheaper glass layup
  • Still unreviewed independently, so every performance claim traces back to Fenn or its dealers
  • New model with a thin used market, and it now overlaps its own sibling: under ~85kg the Sailfish covers the same footprint with less volume
  • Launched into an already crowded Fenn lineup, which drew open scepticism from long-time owners

What paddlers say

Oceanpaddler describes the Spearfish as designed to 'bridge the gap between the renowned Fennix Swordfish and the elite-level skis... the perfect combination of speed, stability, and versatility' across ocean swell and flatwater (oceanpaddler.com)Reported experience
Ocean Surfskis (UK) pitches it at 'SLS paddlers with good beach knowledge looking to make the jump into ocean racing', highlighting the extended footwell for taller paddlersReported experience
"The Spearfish is touted as a 'longer ski which helps to bridge the gap between the Fennix SWORDFISH and the Elite skis'... Innovation and the excitement of new designs aside, the burning question is, did Fenn really have to add new designs to what was already a very successful lineup of boats??" - Nordy announcing the launch, surfski.info thread 20578Reported experience
On the low-volume sibling, not this hull: "When the Spearfish and Sailfish are promoted as 'bridging the gap between the Swordfish and the elite boats' I wondered if that would mean that it was less stable than the Swordy but for me it was noticeably more stable with a really planted (opposite of twitchy?) feel even at a lower weight in full carbon" - CrabStick (73kg, Perth), three paddles on the Carbon Sailfish, surfski.info thread 20625Reported experience
No independent review or owner report of the Spearfish itself has been published as of August 2026 - unusual two years after launch, and worth weighing before buying unseenReported experience

AUD Hybrid $4,350 / Carbon $5,450 (Oceanpaddler AU, 2026); aud_new shown is the Hybrid layup. UK: GBP 2,880 Hybrid / GBP 3,120 Carbon (Ocean Surfskis). The race-ski range has no Glass Vac option. Weights here follow Fenn's factory sheet (12kg/11kg), which the UK dealer matches; Oceanpaddler quotes 12.5kg/10.5kg but publishes those same two numbers for the Spark S and Fennix Elite S as well, so they read as range boilerplate.
