Opium DW

6.45m x 45cm hull named for the job: DW is downwind. Widest of Opium's three long racers, which is the sensible order — the boat you run in big following seas is the one you can still sit on when it is broaching.

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

Rated from the community chart's 45cm beam and 6.45m length against this index's own scale, not from a paddle test. 45cm at 6.45m is the same footprint as the Epic V10 of the mid-2010s.

Suits: Downwind runs and rough open water.

Paddler weight

This hull is built around a paddler of about 93 kg. It stays workable from 82 kg to 99 kg, and sits at its best between 86 kg and 95 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.
