Carbonology Boost X Triple

The Boost X double stretched to 7.8 m with a third seat, on the same 52 cm beam and a 41 cm deck. Buckets are 42 cm wide and 25 cm deep — the deepest in the range — and a wave deflector is fitted as standard. Rated for a 150-300 kg crew.

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

Carbonology scores it 4-5 on its own 1-10 scale, level with or one step off the Boost X double it is based on, and sells it to schools, clubs and hire fleets on stability. Speed is set below the double: the same beam carrying half again as much crew on 60 cm more waterline, in a hull that weighs 23 kg at best, is not a racing proposition. No independent review exists, and no comparable craft in this index gives a second data point.

Suits: Taking two other people out, including children and beginners, in real conditions. Team paddling, university and club events, hire fleets.

Paddler weight

This hull is built around a paddler of about 71 kg per seat. It stays workable from 62 kg to 75 kg, and sits at its best between 66 kg and 72 kg.

Derived from published hull dimensions and calibrated against manufacturer paddler limits, not taken from a marketing range. The method, in full.

Generations

2019-

Joined the fleet in 2019 as the SS3 Boost, based on the Boost X double. The only production three-seat surfski in this index.

What works, and what it costs you

What works

  • The only production triple surfski anyone builds
  • Deep 25 cm buckets and a wave deflector — genuinely built for passengers who are not paddlers
  • Stability of the Boost X double at three-up

Trade-offs

  • 30 kg in glass, and 7.8 m to store and transport
  • Needs three people to be worth launching
  • A$5,000 for a craft most buyers will use occasionally
