On-water profile
Modelled from published beam, length and deck height. Low confidence. Speed is our rating. Both are given at the hull's own design weight.
Stability here means how steady the ski feels sitting still on flat water. Where two craft have overlapping ranges, we can't say which is more stable. Downwind handling is a separate thing, covered in the evidence note below.
Evidence note
Suits: Learning, flat water and light chop.
Paddler weight
The estimated sweet spot is 81–94 kg, with a broader estimated guide of 66–98 kg. This estimate is a guide, not a limit. Seat fit, conditions and paddling style matter. Lighter paddlers can still enjoy a larger hull, especially downwind. A test paddle is the best check.
Estimated from hull dimensions using a formula fitted to makers’ own paddler limits. It does not establish the designer’s intended paddler weight. How this is worked out.
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.
Pros and cons
Pros
- Wide and short enough to learn on
- Easy to car-top and carry
- Part of a range you can move up through
Cons
- No published weight or layup table
- Gives away a lot of speed to the 6m hulls
- Effectively unavailable outside South America
