Layup weights
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. How we rate.
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: Flat water to moderate ocean chop and small downwind runs, especially an experienced paddler steering a newcomer or coaching from the rear seat.
Paddler weight
The estimated sweet spot is 72–83 kg per seat, with a broader estimated guide of 58–87 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
Intermediate double derived from the S18SX single, with the current bucket seat and RT-1 footboard in both cockpits and a longer, low-volume cockpit for a wide fit range. Pitched for racing, surfing and coaching a less experienced partner.
Pros and cons
Pros
- Very wide 56.5cm beam makes it accessible to new paddlers
- Shorter than most race doubles, easier to store and turn
- Large 261kg capacity and wide paddler fit range (1.5-1.95m)
- Useful coaching boat for one-on-one technique work
Cons
- Wide, short hull caps top speed against 7m+ race doubles
- Advantage layup is 22kg, heavy to carry for one person
- Little independent review coverage so far
