Choosing between the AeroCat and Viper isnโt about picking a โgoodโ boat and a โbetterโ one. Both are soft-hull inflatable catamarans with thermo-welded seams, high-pressure air-deck floors and automatic pressure-relief valves. The key decision is how you balance carrying weight and portability against a thicker, more heavy-duty hull.
In simple terms, the AeroCat is for buyers who want a practical, lighter inflatable catamaran thatโs easier to transport and store. The Viper is for boaters who put a higher priority on hull toughness and regular use in demanding conditions.

The ranges share Aerowaveโs catamaran design approach and construction features, but their hull fabrics are different. Thatโs the practical trade-off to focus on.
The real difference is the fabric
The AeroCat uses 0.9 mm, 1100 decitex German VALMEX. Itโs a considered choice for boaters who want a more manageable package: lighter to handle, easier to pack away and typically more affordable than a Viper.
The Viper steps up to 1.2 mm, 1500 GSM VALMEX Heavy Plus. That thicker fabric is designed for greater resistance to abrasion and punctures. If you boat often, land on beaches regularly or spend a lot of time on the water, the added material may be worth the extra weight and cost.
Neither fabric makes the boat immune to damage. Good handling, sensible launch choices and rinsing and drying the boat after use still matter. The decision is about choosing a suitable level of hull material for the places and frequency you boat.

How much do the boats weigh?
Weight is often the deciding factor for someone searching for an easy to carry inflatable boat. The AeroCatโs thinner fabric makes it the lighter choice size for size. Check each model page for the current bare-boat weight, which excludes items such as the Bimini and wheel kit.
Compare the exact modelโs current boat weight, packed dimensions and inclusions before ordering. Include the floor, seats, motor and accessories when planning vehicle payload and handling.
Who should choose the AeroCat?
Choose an AeroCat if easy handling and storage are central to how youโll use your boat. It suits buyers who want the stability and open deck of a twin-hull inflatable but donโt want to make every outing a heavy lifting job.
It can be a strong match for:
- Camping and touring: pack the boat away between trips instead of reserving space for a trailer.
- Caravan and 4WD travel: make a portable boat part of the trip, subject to checking your vehicleโs available space and payload.
- Calmer-water fishing and exploring: take the boat to bays, rivers, lakes and sheltered coastal spots.
- Yacht owners: use a lighter inflatable catamaran for ship-to-shore trips where stowage and handling matter.
- Buyers watching overall value: the AeroCat offers a lower-cost way into the Aerowave catamaran range, while retaining core features such as welded seams and pressure-relief valves.
The AeroCat Series includes the 335, 365, 380 and 400, so you can choose a size that fits your crew and storage plans. As the model grows, so does its weight: the larger sizes are not a one-person lift for everyone, particularly with accessories packed alongside. Check the modelโs packed dimensions and consider how youโll move it from vehicle to water.
Who should choose the Viper?
Choose a Viper if durability comes before minimising weight. Its thicker VALMEX Heavy Plus fabric is intended for buyers who expect more frequent use, rougher handling or more demanding launch and landing conditions.
Vipers are worth considering for:
- Family adventure boating: choose a size that gives your passengers and gear room without exceeding your vehicle or handling limits.
- Regular fishing trips: a stable platform and practical deck layout can make it easier to fish with rods and equipment aboard.
- Rougher shore access: thicker fabric offers an extra measure of abrasion and puncture resistance, although care is still essential.
- Boaters who plan to use their boat often: a heavier-duty hull may better suit a higher-use routine.
- Buyers who value longer structural cover: the Viper has a five-year warranty plus two extended structural years, subject to the warranty terms.
The Viper Series runs from the compact Viper 330 through to the 450. A larger model may offer more room and a more substantial platform, but it will also take more space and effort to move. Choose based on your actual crew, storage and launch plan, not just the biggest number in the range.

What both ranges have in common
AeroCat versus Viper is not a choice between basic and fully featured. Both ranges share several practical construction details:
- Thermo-welded seams, where compatible material seams are fused with heat rather than relying on adhesive alone.
- Automatic pressure-relief valves to help release excess pressure as air inside the tubes warms.
- High-pressure air-deck floors for a firm, supportive surface underfoot when inflated to the specified pressure.
- Catamaran hull layouts designed to provide a stable platform for recreational use.
Both require sensible care. Follow the ownerโs manual for inflation, use the recommended pressures, and inspect the tubes and fittings before heading out. Setup takes approximately 15 minutes, depending on conditions, experience and the package being assembled. Allow time for checks and loading your safety gear too.
Which Aerowave series suits how you boat?
If youโll carry your boat often, travel with it or store it in a compact space, start with the AeroCat. Itโs the more portability-oriented choice, and its 0.9 mm VALMEX hull keeps weight and price in check.
If your priority is a tougher hull for more demanding use, consider the Viper. Its thicker 1.2 mm fabric is the clear distinction, with additional weight as the trade-off.
