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

This is the Sovereign difference: a premium enclosed-bow 4m catamaran built with German VALMEX® 7321 Heavy Plus 1.2mm commercial-grade fabric, thermo-welded construction, a high-pressure 12 PSI air deck, over-inflation safety valves, and a complete flagship package designed to sit above cheaper inflatables and generic look-a-likes.
Winter Special Package Deal
Was AUD $6,295 — now AUD $5,295. Save AUD $1,000. Valid until 31 August 2026.
The flagship Viper for buyers who want the best version
The Viper 400 Open Bow show offer sits at $5,995. The Sovereign at $5,295 now gives buyers an even sharper flagship enclosed-bow package — a more refined, more family-friendly, more serious Viper package at stronger show-special value.
- Flagship status — the top Viper package for buyers who want the most premium 4m layout in the range.
- Premium material spec — German VALMEX® 7321 Heavy Plus 1.2mm commercial-grade fabric and thermo-welded construction.
- 12 PSI air deck — a firmer, more rigid underfoot feel when standing, fishing or moving around.
- Enclosed-bow confidence — a more refined front-end layout for a stronger, more complete flagship look.
Factory-Built Confidence
The Viper 400 Sovereign is built using premium German VALMEX® 7321 Heavy Plus 1.2mm commercial-grade fabric, precision thermo-welded tube construction and factory-controlled assembly standards. Reinforced tube and transom construction, clean finishing standards and over-inflation safety valves contribute to a stronger-spec package.
Why the fabric really matters
- German VALMEX® 7321 Heavy Plus 1.2mm commercial-grade fabric delivers stronger puncture and abrasion confidence.
- Better UV resistance for harsh Australian conditions.
- Thermo-welded seams support tougher long-term saltwater ownership.
- Over-inflation safety valves help protect the tubes when pressure rises in hot weather.
Ownership outcomes — what you're really buying
- More family confidence — a stable twin-hull platform that feels more predictable when passengers move around.
- Firmer underfoot feel — the 12 PSI air deck delivers a more rigid, serious boat-like footing.
- Fewer surprise extras — important gear is already included.
- Flagship pride of ownership — looks and feels like the top Viper, not just another inflatable.
