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

Rated from the community chart's 43cm beam and 6.45m length against this index's own scale, not from a paddle test. That footprint matches the Think Uno and the Fenn Mako Elite, which is the class this hull is built for.

Suits: Ocean racing and downwind for an experienced paddler.

Paddler weight

This hull is built around a paddler of about 88 kg. It stays workable from 78 kg to 94 kg, and sits at its best between 82 kg and 90 kg.

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

Generations

current

Opium Caiaques is a Brazilian builder with the widest ski range in South America — seven surfskis from an elite 6.45m racer down to a 5.25m beginner hull, alongside OC1, OC2 and OC6 outriggers. Opium publishes an overall hull height for each boat; that figure is not the deck height this index uses for weight bands, so it is not carried across.
