Dimension estimateLow confidence

Modelled from published beam, length and deck height. Low 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 estimated from published dimensions. Qualitative context includes 2 paddler reports and 3 linked sources.

Suits: Flat water, learning surf, moderate chop and downwind for less experienced paddlers; PE tolerates rock/reef launches the composite skis can't.

Paddler weight

The estimated sweet spot is 70–81 kg, with a broader estimated guide of 57–84 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

2015-2016 (discontinued; not in current thinkkayak.com lineup as of Jul 2026)

Co-developed with UK's Pyranha Kayaks and rotomoulded there; sold as both 'Pyranha Octane' and 'Think Nitro' (same boat). A rotomoulded (PE) answer to the Epic V7, NOT a composite race ski.

Pros and cons

Pros

  • Durable PE construction, tolerant of beach/rock launches
  • Near composite-race-ski speed for a plastic boat
  • Much cheaper entry point than composite Think skis
  • Good primary/secondary stability for learning

Cons

  • Heavy (~23-24kg vs 10.5-15.5kg for composite)
  • Discontinued and hard to find; no current AUD stock
  • Awkward carry handles
  • Limited storage

What paddlers say

seakayakphoto.com: on flat water 'proved remarkably stable while moving', hitting 97.6% of a friend's Epic V8 Pro's top speed.Reported experience
seakayakphoto.com: 'challenging in steep surf zones compared to shorter decked kayaks'; remounting needs practice.Reported experience
