Before you compare price
Why not all 4m inflatable catamarans are the same
A cheaper inflatable can look good in photos, but the real difference shows when you load the boat, move around, launch from the beach, spend a full day in the sun, or run in Australian chop. The Viper 400 is positioned as a premium ownership-ready 4m off-shore catamaran package, not a bare inflatable hull with the important extras still to buy.
☑ Stability-first hull
The catamaran platform is designed to feel planted at rest, giving families and fishos more confidence when passengers or gear move around.
☑ Premium material spec
German 1.2mm 2000D Mehler Valmex® PVC and thermo-welded seams help separate the Viper from lighter-duty look-alike inflatables.
☑ Complete package value
Bimini, LockPro wheels, lithium pump, rod holder mounts, seats, delivery and support are part of the offer — reducing surprise spending later.
☑ Australian ownership support
Free DDP Australia-wide delivery, price-lock once secured, setup guidance and Australian support help make ownership easier from day one.
Simple way to compare: do not compare the Viper 400 only by length. Compare the hull stability, floor pressure, fabric grade, included gear, freight protection, warranty support and how complete the boat is when it arrives.
Premium complete package pricing
Viper 400 Complete Package — priced as a serious ownership-ready 4m catamaran
The Viper 400 is the hero model of the Viper range and the package most buyers should seriously consider. It is not priced like a stripped-back inflatable because it is not built or supplied like one. This package includes the bimini, LockPro Plus wheel system, 22 PSI lithium battery air pump, 2 x rod holder mounts, 2 x aluminium bench seats, premium hull construction, and FREE DDP Australia-wide delivery.
Price appeal: many lower-priced boats look cheaper upfront because they are not truly ownership-ready. Once you add wheels, shade, electric inflation, rod holders, delivery, warranty support and setup help, the real comparison changes quickly.
Viper 400 Hull Package
$5,495
For buyers who want the premium 4m catamaran hull platform and prefer to add selected accessories later.
Ownership-ready setup — the smart choice for most Viper buyers.
☑ Full grey bimini included
☑ LockPro Plus wheels included
☑ 22 PSI lithium pump included
☑ Rod holder mounts included
☑ 2 x aluminium bench seats included
☑ Free DDP Australia-wide delivery
This is the package most buyers should choose because it delivers the best balance of size, stability, included gear and long-term ownership value.
Why this is important to the buyer: the Viper 400 Complete Package is priced to reflect a properly equipped premium 4m offshore inflatable catamaran with major ownership extras, freight protection and Australian support already built into the offer.
What “Cheaper” Inflatable Boats Actually Cost
Many inflatable boats appear cheaper upfront, but freight, import costs, upgrades and material differences can quickly change the real ownership cost.
Typical Imported 4.0m Package
✕ Advertised around $4,000–$5,500
✕ Freight can add $600–$1,000
✕ GST/import costs may add $400–$600
✕ Accessories may still need adding
✕ Real delivered cost can reach $5,000–$7,100+
✕ 0.7mm or 0.9mm / 1100D fabric (~33% thinner than 1.2mm commercial-grade PVC)
Viper 400 Package — $6,495
☑ Fixed package price
☑ FREE DDP Australia-wide delivery
☑ No hidden import/GST surprises
☑ Major ownership extras included
☑ 1.2mm German 2000D Valmex®
☑ Thermo-welded seams
☑ Built for long-term Australian use
The biggest take home difference: the Viper range uses 33% thicker 1.2mm 2000D commercial-grade Valmex® PVC, giving buyers stronger durability, higher ownership confidence and better suitability for real Australian conditions.
*Comparison is general only and based on typical similarly sized imported inflatable boat packages. Specifications, freight, inclusions and final costs vary between brands, suppliers, regions and promotions. Always compare written specifications and delivered pricing before buying.

The Viper 400 Complete Package is designed for owners who want a 4m inflatable platform that feels stable at rest, predictable underway, and confidence-inspiring when family, mates, or fishing gear move around on board. The twin-hull catamaran layout reduces roll, while the 12 PSI hard-air-deck floor gives a firmer, more planted, boat-like feel under load.

Premium VIPER 400 build detail
Factory Built Confidence
The Viper 400 is built using premium marine materials, precision tube construction, and factory-controlled assembly standards designed for long-term ownership confidence. This section shows the sort of real build detail that separates the Viper 400 inflatable catamaran from lighter-duty look-alike alternatives. Over-inflation safety valves are also part of the stronger-spec ownership detail many cheaper boats leave out.
Early-stage hull build
Showing the boat at a more raw build stage helps you see genuine factory construction detail before the premium finishing work is completed. The upside down grill on the transom is part of the build.
Precision construction
Reinforced seams and transom work, careful tube assembly, and clean finishing standards help deliver the stronger premium look and feel buyers expect from the Viper 400.
Finished premium result
This is the type of clean, premium final finish that gives buyers more confidence they are stepping up to a serious inflatable catamaran built for real use.
LockPro launch-ready setup
The fitted LockPro wheel set shows the sort of practical premium detail buyers appreciate — easier beach handling, easier boat ramp launching, and a more complete ownership-ready setup from day one. Grey wheels also available. Check the wheels out here!
Why this matters for you as the buyer
More confidence in what you are paying for because the build quality is visible, not just claimed
Stronger premium positioning compared with lighter-duty inflatables that look generic online
Better long-term ownership confidence when construction standards and materials are taken seriously
More trust before purchase because buyers can see real manufacturing and finished-product quality
Better protection in Australian heat with over-inflation safety valves included as part of the build spec
Flexible ordering options
50% deposit option
New boat builds can be secured with a 50% deposit at the time of order, helping you lock your build slot without paying the full amount upfront.
Clear custom build process
Deposits accepted by EFT, credit card, or debit card. Remaining balance is payable prior to dispatch. Estimated turnaround for custom builds is approximately 4–5 weeks.
Why the fabric really matters
Commercial-grade German Mehler Valmex® fabric chosen for stronger abrasion confidence, UV resistance, and long-term ownership value.
Not all PVC inflatable boats use the same material specification. The Viper 400 is built with German 1.2mm 2000D Mehler Valmex® PVC, giving you a more abrasion-resistant, higher-confidence hull for beach launches, regular fishing use, gear loading, and long-term ownership in Australian conditions.
Thermo-welded seams reduce reliance on glue in key construction areas
Better UV and saltwater confidence matters in real Australian conditions
Higher-quality materials support longer-term ownership, not just first impressions
Over-inflation safety valves help protect the tubes when pressure rises in hot weather

What is the benefit of the 12 PSI floor?
The higher-pressure hard-air-deck floor gives a firmer, more rigid underfoot feel than softer inflatable floor designs, without needing heavy panel assembly.
