1.2mm Viper — folds away like a 0.9mm tourer.
Two short videos showing exactly how the Viper packs up into the Bluewater kit bag and stows on a caravan, ute or RV. Thicker fabric, same easy fold.
Viper 1.2mm — Folded Into The Bluewater Kit Bag
Watch a full Aerowave Viper 1.2mm catamaran fold down and slide into a single Bluewater kit bag. 33% thicker than TrueKit — and still travel-ready. Caravan, ute tray, or RV gas-bottle nook: it stows.
Inflate, Deflate, Stow — The Aerowave Viper Workflow
From rolled-up to on-the-water and back again. Our commercial-grade 1.2mm Valmex doesn't punish you for going thicker — deflation and pack-down are just as fast as a flimsy 0.9mm tourer.
Overview
4m Inflatable Catamaran Australia — Aerowave Viper 400
The premium 4m inflatable catamaran package built for Australian families, fishos and coastal adventure buyers who want stability, strength and real long-term value.
This is not a cheap bare inflatable. The Viper 400 is positioned as a complete ownership-ready 4m catamaran package with premium fabric, a 12 PSI hard-air-deck floor, practical fishing and beach-launch gear, delivery support and Australian-backed confidence.
Winter Special — Save $500
Winter Special $5,495 (RRP $5,995). Save $500 until 31 August 2026. Price locked once deposit received. Limited production allocation.
Why buyers choose the Viper 400
- Less roll at rest from the twin-hull catamaran layout
- Rigid underfoot feel from the 12 PSI hard-air-deck floor
- Drier ride design with added bow flare to help throw spray away
- More secure working layout for fishing, gear and day use
- Built for Australian conditions with premium fabric and pressure protection
Premium build detail
The Viper 400 uses premium marine materials, precision tube construction and factory-controlled assembly standards designed for long-term ownership confidence. Thermo-welded seams, reinforced transom work and over-inflation safety valves are part of the stronger-spec ownership detail many cheaper boats leave out.
