Fenn Fennix Yellowfin

Mid-volume, moderately wide beginner-to-intermediate ocean hull with reduced rocker and extra waterline for glide. Low gunnels make remounts easy; forgiving primary stability with enough speed to progress into downwind.

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 1 paddler report and 3 linked sources.

Speed is also checked against the traced hull. Measured from this boat's side and plan photos, the shape alone rates 6, and the score shown is moved a third of the way toward that. What that means.

Suits: Flatwater fitness, learning ocean paddling and first downwind runs for paddlers ~60-95kg

Paddler weight

The estimated sweet spot is 75–88 kg, with a broader estimated guide of 61–91 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

2024-2025 (introduced)

Newest entry/intermediate model in the Fennix range; slots between the Fennix Blue-Fin and XT S, ~140mm longer waterline than both for glide, lower gunnels for easier remount

  • Longer/faster than the Blue-Fin yet still stable
  • Three layups including affordable Glass Vac

Cons

  • Not a race hull: capped top speed
  • New model, thin resale market
  • Heaviest at 14kg in Glass Vac

What paddlers say

Pro Kayaks lists the Yellowfin as a 'Beginner to Intermediate Surf Ski... built for performance, safety, and versatility' with 'lower gunnels allowing for an easier remount' (shop.prokayaks.com.au)Reported experience
