Layup weights

On-water profile

Stability
7.0
Speed
6.0

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

Reviewer (seakayakphoto.com) called it 'remarkably stable' with primary stability 'hard to beat', and measured it at 97.6% of an Epic V8 Pro's top speed despite plastic build; forgiving but well below composite race skis on speed.

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

This hull is built around a paddler of about 79 kg. It stays workable from 69 kg to 84 kg, and sits at its best between 73 kg and 80 kg.

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

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.

What works, and what it costs you

What works

  • 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

Trade-offs

  • 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

Where to buy

The Nitro is out of production. It turns up on the second-hand market; there is no new-boat channel for it.
