Look how easy it packs into the back of a Mazda CX-5.
Drop the two split rear seats and the whole rig slides straight in — boat, high-pressure Air Deck floor, both aluminium bench seats, the oars, the under-seat bag, the Bimini (pulled apart and packed flat), the 22 PSI lithium pump, a small scud-type anchor and accessories, plus the outboard, fuel tank and life jackets. No trailer, no boat ramp queue. Pull up, carry it down, and you're on the water.
The bag pictured has an actual AeroCat 360 packed inside it, with the high-pressure Air Deck floor added. Our boat bags take everything up to a Viper 430.
- · Hull, Air Deck floor, 2× aluminium seats and oars all in the one bag
- · Under-seat bag, dismantled Bimini, 22 PSI lithium pump and scud anchor alongside
- · Fits a mid-size SUV boot with the rear seats folded
- · Garage-friendly storage — no trailer parking
Packs smaller. Lifts lighter. Actually gets used.
How the AeroCat 400 packs down against a same-length rival inflatable catamaran. Competitor figures are typical published ranges for boats of this size — check them against whatever you are cross-shopping.
See the AeroCat 400 go from one large Aerowave bag to on the water — and back again.
Weights are bare boat, without Bimini or wheel kit. Packed dimensions are the supplied ripstop PVC bags. Rival figures are indicative ranges for same-length inflatable catamarans with alloy or slat floors.
Compare the landed price, not just the hull price.
Every price on this page includes air freight to your door Australia-wide. The AeroCat keeps the package light and practical while showing the real delivered price upfront—no freight surprise at checkout.

The full numbers
AeroWave AeroCat 400 Inflatable Catamaran — Full Package
What's included in the Full Package
17 items- 01Colour-matched Bimini sun top — included
- 02LockPro Plus wheel kit — fitted during production
The stainless mounting plates are secured to the transom with eight lugs, and the wheel storage bag is included.
- 034 × Over-Inflation Safety Valves (one per chamber) — standard on every boat. Most competitors don't include these.
- 04Heavy-duty bow bridle
- 052 × Aluminium bench seats
- 068–10 PSI high-pressure hard AirDeck floor
Use the lithium pump only for the first minute, until the floor reaches approximately 2–2.5 PSI. Then switch to the supplied manual pump to reach the recommended 8–10 PSI. Do not use the lithium pump for final AirDeck pressure; it will not bring the floor to 8–10 PSI. The lithium pump is suitable for the boat tubes, where the over-inflation valves control excess pressure.
- 0722 PSI 12V lithium electric air pump with built-in battery — included
- 082 × padded under-seat storage bags with cushion tops — included — One bag carries Easy Inflatables branding; the other is identical in size, material and quality — just unbranded.

Factory-to-door quality control and compliance checks
Before your boat leaves the factory, we run an eight-point quality control and compliance check against your exact order — fabric, seams, transom, inflation, fittings and pack list — so what arrives at your address is what you paid for.
Build sheet lock
Factory confirms hull colour, length, transom spec, floor type and fittings against your order before fabric is cut.
Fabric spec verification
We cross-check the VALMEX® GSM and thickness rating against the signed-off sample so the hull matches what was promised.
Seam and weld inspection
Every main seam, transom joint and chamber bond is pressure-tested and visually inspected before full inflation.
Transom and fitting stress check
Transom height, backing plate and motor-mount geometry are verified against the rated HP max for your model.
Chamber inflation test
Each air chamber is inflated to operating PSI and held to confirm no creep, leaks or valve faults before the boat is signed off.
Pre-shipment photo pack
We receive factory photos of your actual boat before it leaves, so any issue is caught before freight, not after.
Final pack-list audit
Seats, bags, Bimini, pump and accessories are checked off against your configured package list before the carton seals.
Door-step arrival check
You inspect on delivery. If anything does not match the compliance pack, we sort it — no arguments, no run-around.

Frequently asked questions
What's the difference between the Viper and the AeroCat?
Both ranges use premium German VALMEX® fabric — the difference is thickness. Viper hulls use the heavier 1.2mm VALMEX® for maximum durability, while AeroCat hulls use a lighter 0.9mm VALMEX® so they fold smaller and pack lighter. That means the AeroCat packs down more easily into the Bluewater heavy-duty kit bag, making it simpler for one person to load, launch and store — while keeping the same twin-hull catamaran stability.
What motor suits the AeroCat 400?
The AeroCat 400 is rated up to 25HP 4-stroke short shaft, with 20–25HP recommended for most buyers depending on load and use.
Is delivery included?
Yes — delivery is included in the price of every boat. Your boat ships by express courier (DHL Express, FedEx or UPS) door-to-door, up to 2 weeks after it is built. GST, import duty and customs clearance are all covered, so there is nothing to pay on arrival. The only extra is a flat A$300 remote delivery fee for a small number of remote Australian postcodes — that is our own charge for the extra road leg, not a courier surcharge. Enter your postcode in the checkout box above to see if it applies.
What warranty do I get?
Every AeroCat is backed by our 5-Year Australian Structural Warranty — supported locally, not just an import promise.
Why is it priced below comparable 0.9mm imports?
We import direct and price the AeroCat ~$500 below comparable 0.9mm catamarans on the Australian market, while still including the Bimini, pump, wheel kit and accessory package options.
How do I inflate the hard AirDeck floor to 8–10 PSI?
Use the lithium pump only for the first minute, until the floor reaches approximately 2–2.5 PSI. Then change to the supplied manual pump to reach the recommended 8–10 PSI. Do not use the lithium pump to try to reach final AirDeck pressure; it will not work. The lithium pump is suitable for the boat tubes, and their over-inflation valves control excess pressure.
