Modelled from this hull's traced beam and depth at its design weight. Medium confidence. Speed is our rating. Both are given at the hull's own design weight.

These ratings are Surfski Index estimates, worked out from published dimensions, traced hull shapes where we have them, and reviews. They are not supplied by the maker or timed on the water. How a ski feels depends on your weight, skill, set-up and the conditions, so use them to shortlist skis and paddle one before you buy. 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

This band is based on a trace of this hull’s geometry. Qualitative context includes 2 paddler reports and 4 linked sources.

Speed is also checked against the traced hull. Measured from this boat's side and plan photos, the shape alone rates 7, and the score shown is moved a third of the way toward that. What that means.

Suits: Learning surf, downwind and open water; calm-to-moderate chop for beginners, small runs and training for improvers.

Paddler weight

Carbonology rates this hull for paddlers from 80 kg to 120 kg.

The maker’s published range. How this is worked out.

Pros and cons

Pros

  • Stable base with real speed for the class
  • LV option for lighter paddlers
  • Good all-round surf/downwind/training ski
  • Wide weight range (single 50-120kg)

Cons

  • Boost LV footwell reported slow to drain (bailer only from ~8-10km/h)
  • Not as fast as advanced skis
  • Cheaper glass layup is heavy

What paddlers say

Esteban Medina (Livingsea): 'For the stability it has, the Boost X LV will give you a lot of speed'; learners feel stable in calm seas within weeks, minimal remount difficultyReported experience
surfski.info: some LV owners note footwell stays wet until ~8-10km/h, unlike the early-draining CruzeReported experience
