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