The specification comparison

Why Easy Inflatables.
1.2 mm VALMEX®, 7-year hull warranty, CE certified.

Most inflatable boats in this size range are sold on length, horsepower and a photograph. We think three numbers decide whether the boat is still yours in ten years: the fabric thickness, the warranty term, and the standard it is certified to. Here is where the Aerowave range sits on all three, against the claims you will read everywhere else.

The three numbers worth arguing about

1.2 mm

Hull fabric thickness

1500 GSM VALMEX® Heavy Plus. 33% thicker than the 0.9 mm class.

7 years

Viper hull warranty

Five years standard plus extended Years 6–7 on the Viper Series.

ISO 6185-3

Certified build standard

Plus EU Directive 2013/53/EU. CE plate supplied with the boat.

The 4.0 metre catamaran class, side by side

Aerowave against the two boats you are already cross-shopping.

Every figure in the two right-hand columns was taken from those makers’ own published specification pages and price lists on 1 October 2026. Where a maker does not publish a number, the table says so rather than guessing. We name them because the comparison only works if a shopper can open the same pages and verify the numbers for themselves.

Landed-cost comparison of all three 3.8–4.0 m packages — boat, the accessories you would need to match our package, and delivery to Australia. No adjectives, no opinions — just the published specs, prices and warranty terms.

3.65–3.8 m packages

Viper 365

A$5,295

Takacat 380LX

A$6,296

+ delivery

You save at least A$1,001 with Aerowave

The A$6,296 comparison includes its published bimini, wheels, electric pump and rod holders. Delivery and an equivalent second seat and under-seat bag are still extra or unpriced, so the final saving is higher.

4.0 m packages

Viper 400

A$5,395

Discovery 4.0

A$6,781

estimated landed

You save about A$1,386 with Aerowave

The A$6,781 matched-equipment estimate starts with the current A$4,562 Discovery Package, then adds the published bimini, rod holders and seat bag, an A$279 electric-pump benchmark, captured NSW freight, estimated import GST and A$65 handling.

How we compared these packages. Every claim above is on a public web page. Open both makers’ specification tabs, search for the fabric thickness in millimetres, the GSM, the transom height and the warranty term, and put them beside ours. Prices captured 1 October 2026 and reviewed quarterly; competitors change theirs without notice, so confirm on the day you buy. The price comparison above is the landed cost for an Australian buyer — boat, matching accessories and delivery. No adjectives, no opinions — just the published figures.

Looking at something cheaper? Read our honest answer on cheap inflatable boats in Australia — what a sub-A$4,000 hull actually costs you over ten years. And if you have ever had a hull come unglued, here is why seams fail and what our Owner Promise does about it.

WHERE WE SIT IN THE MARKET

Cheap inflatables fail the same way, every time.
This is where we build differently.

Thin fabric, glued seams that creep, a transom that works loose in season two. We build to the European material standard — 1.2 mm VALMEX®, a custom-built commercial-spec 380 mm transom — and back it with a 7-year Viper hull warranty.

What you are actually buying

1500 GSM / 1.2 mm VALMEX® Heavy Plus

The Viper Series hull is built on German VALMEX Heavy Plus — 33% thicker than the 0.9 mm fabric used across most comparable 3.3–4.5 m inflatables. Thicker fabric is what survives oyster racks, rock ramps, gravel launches and a season of trailer abrasion.

Read The 1.2 Rule

7-year Viper hull warranty

Five years standard plus extended Years 6–7 hull cover on the Viper Series — on both the 1.2 mm VALMEX hull and the Orca Hypalon upgrade. Sport, WaveRunner and AeroCat ranges carry the 5-year hull warranty.

Read the warranty

CE certified to ISO 6185-3

Every Aerowave catamaran is built and certified to ISO 6185-3 and EU Directive 2013/53/EU, with the CE plate and Statement of Conformity supplied with the boat.

Safety & compliance

Landed pricing, no hidden import fees

You see the price that lands at your door, not an ex-works number with a customs bill behind it. Freight and duty are stated up front on every quote.

Shipping & landed cost

Parts held, not promised

Valves, seats, floor panels, handles and transom hardware are stocked in Australia and at our offshore hub, shipped DHL Express so a small part never ends a season.

Spare parts

Real people on the phone

Talk to the crew

The part most comparison pages leave out

We sell 0.9 mm boats too. The AeroCat Series is built on German VALMEX 1100 decitex / 0.9 mm PVC, carries a 5-year hull warranty rather than seven, and has a typical service life of 3–7 years depending on UV, storage and use. We publish that because it is priced honestly for what it is.

What we object to is 0.9 mm sold as though it were something heavier, with a service life implied that the fabric cannot deliver. If you want the ten-year boat, buy 1.2 mm. If you want a well-built weekend boat at a lower price, buy the AeroCat with your eyes open. Either way you should know which one you are paying for.

Six questions to ask any inflatable boat seller

Ask us the same six. Every answer above is on this page already.

  1. 01What is the hull fabric, in GSM and millimetres, in writing?
  2. 02Is the hull warranty published before purchase, and how many years cover the tubes?
  3. 03Which standard is the boat certified to — and can you see the Statement of Conformity?
  4. 04What is the transom height in millimetres?
  5. 05What is the landed price at my door, including freight and duty?
  6. 06Which spare parts are held in stock today, and how are they shipped?

Want the numbers for your build?
