Carbonology Crest X

A 6.05 m x 49 cm intermediate hull with a 34 cm deck, one centimetre wider and ten centimetres longer than the Boost X it sits above. Carbonology builds it as a single size with no low-volume sister, and rates it for any paddler weight, which puts the volume between the Boost X and the Zest X rather than at either end.

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

No independent review or owner report exists yet — the ski was introduced in 2025 and nothing has been published on it beyond maker and dealer copy, so this is read off geometry and off the two skis it was drawn between. Stability: computed metacentric height at 78 kg (0.074 m) is fractionally above the Zest X and below the Boost X, exactly where the maker places it, and Australian Paddle Sports rates it 4/5 against the Zest X's 3/5. Speed: it is 15 cm shorter and half a centimetre wider than the Zest X, so it cannot be the faster hull, and it lands level with the Boost X — 10 cm more waterline against 1 cm less beam is a wash at this scale. What the Crest X actually adds is fit rather than pace: it is the one hull in the range Carbonology rates for all paddler weights, where the Boost X is 80-120 kg and the Boost X LV 40-80 kg. Treat it as provisional until someone paddles one and writes it up.

Suits: Ocean chop, downwind runs and club racing for a paddler who has outgrown an entry hull but does not yet want a 46 cm boat under them.

Paddler weight

This hull is built around a paddler of about 98 kg. It stays workable from 87 kg to 104 kg, and sits at its best between 91 kg and 100 kg.

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

Generations

2025-

Introduced in 2025 to sit between the Boost X and the Zest X — the gap Carbonology had left between its entry hull and its intermediate one. Sold in a single size; there is no Crest X LV.

What works, and what it costs you

What works

  • Fills the real gap between the Boost X and Zest X rather than overlapping either
  • Rated for all paddler weights, so it does not need an LV sister
  • Same layup ladder and price as the rest of the composite range

Trade-offs

  • New enough that no independent review exists
  • Only one size, so a very light or very heavy paddler is better served either side of it
  • Not yet listed on Carbonology’s own website, only through dealers
