Three fabric grades. Yours to choose.
Most competitors in this market only build in 0.9mm fabric. We give you the choice: 0.9mm VALMEX® on the AeroCat, 1.2mm VALMEX® Heavy Plus on the Viper (33% thicker hull), or step up to Orca CSM/Hypalon for the toughest tropical and commercial conditions.
Lightweight / tender
0.9mm VALMEX®
What most competitors build. We do too — on the AeroCat.
- 0.9mm German VALMEX® fabric
- Light enough to launch solo
- Perfect yacht tender / day boat
- Not built for heavy commercial duty
Serious skippers
1.2mm VALMEX® Heavy Plus
33% thicker than 0.9mm. Built on the Viper.
- 1.2mm Heavy Plus hull — 33% thicker
- 5–7 year hull warranty
- 12 PSI high-pressure air deck — no flex
- Same fabric as workboats & rescue craft
Premium upgrade
1.2mm Orca CSM/Hypalon
The fabric used on top-tier commercial RIBs.
- Superior UV resistance — tropical-rated
- Maximum abrasion & chemical resistance
- Available as an upgrade on any Viper
- Built for saltwater commercial service
One brand. Three hull grades. Pick the boat that matches how hard you push it.
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
