Tinny vs Inflatable Boat: The True Cost of Ownership in Australia (2026)
A tinny looks cheaper on the ad. Then comes the trailer, the rego, the storage and the ramp. Here is the honest five-year cost of an aluminium tinny against an inflatable catamaran you keep in the boot.

Boats in use — offshore, on rivers, on rescue duty. Photos and words from the people who actually own them.
Read owner storiesSearch "tinny for sale" and you will find a 3.7m aluminium hull for a few thousand dollars. It looks like the cheapest way onto the water in Australia. For a lot of people it is not, and the reason has nothing to do with the boat.
The purchase price of a tinny is the start of the bill. The trailer, the registration on two assets instead of one, the storage, and the ramp queue every Saturday are the parts nobody prices in until they are already paying them.
What you are actually comparing
| Aluminium tinny (3.7m, secondhand) | Inflatable catamaran (3.3m) | |
|---|---|---|
| Boat | A$3,000–5,000 | From A$4,295 |
| Trailer | A$1,500–3,500 | Not required |
| Boat registration | Required in every state | Required in every state |
| Trailer registration | Required, annual | None |
| Storage | Driveway, yard or paid storage | Boot of the car or a garage shelf |
| Launch | Ramp only | Beach, ramp, riverbank, sandbar |
| Deep-water stability | Depends on hull and load | Two full-length hulls, wide beam |
The boat prices are close. Everything underneath them is not.
The five-year number
Here is a conservative five-year view for an owner who gets out roughly twice a month. Figures are indicative Australian retail ranges, not quotes.
Tinny
- Trailer: A$1,500–3,500 up front
- Trailer registration: A$150–300 per year — around A$1,000 over five years
- Trailer maintenance (bearings, tyres, lights, rust): A$150–400 per year
- Storage if you have no yard: A$40–80 per month — up to A$4,800 over five years
- Ramp parking and fees: small, but constant
Even with a free driveway and no paid storage, the trailer alone realistically adds A$3,000–6,000 across five years.
Inflatable catamaran
- No trailer, so no trailer purchase, rego, tyres, bearings or lights
- Stores deflated in a carry bag — a garage shelf or the boot of a mid-size SUV
- Launch wheels instead of a ramp: a one-off accessory, not an annual cost
- Hull warranty: 7 years on the Viper series, 5 years on the AeroCat series
Over five years the inflatable typically lands thousands of dollars ahead, before you count the weekends you did not spend queuing at a ramp.
The costs that never appear in a spreadsheet
Ramp dependency. A tinny goes where a ramp goes. An inflatable catamaran with launch wheels goes down a beach, off a riverbank, or off the sand at a spot with no infrastructure at all.
The two-person problem. Plenty of tinnies stay in the yard because reversing a trailer solo, in wind, at a busy ramp is not most people's idea of a Saturday. A catamaran that one person can carry, inflate and launch alone gets used far more often.
Corrosion and dents. Aluminium bruises on rocks and oyster-covered ramps, and saltwater finds every fastener. Heavy PVC tube fabric flexes off the same hits.
Trailer theft and rust. A trailer is a second asset sitting in your driveway that requires maintenance, insurance and attention.
Where the tinny still wins
Honest answer: it sometimes does.
- You want to leave it rigged, motor on, ready to hook up and go with zero setup.
- You tow long distances at highway speed and want the boat to live outside permanently.
- You are running big horsepower and long offshore legs where a heavier rigid hull suits the job.
If that is you, buy the tinny. If your real-world boating is bays, estuaries, rivers, beaches, headlands and half-day fishing trips, the maths flips hard the other way.
What our boats cost, plainly
| Model | Length | Price |
|---|---|---|
| AeroCat 330 — Ready-to-Fish Pack | 3.3m | A$4,295 |
| AeroCat 360 | 3.6m | A$4,595 |
| AeroCat 380 | 3.8m | A$4,795 |
| Viper 330 Sports Package | 3.3m | A$5,195 |
| Viper 400 Open Bow Sports Package | 4.0m | A$5,895 |
AeroCat hulls use 1100 GSM / 0.9mm German VALMEX®. Viper hulls use 1500 GSM / 1.2mm VALMEX® Heavy Plus — the reason they carry a 7-year hull warranty. Premium VALMEX fabric has a working life of 10–12 years in Australian conditions.
Registration still applies
Do not skip this. An inflatable catamaran with a motor is a registrable vessel in every Australian state, exactly like a tinny. The difference is you register one thing instead of two. Check your state authority for the rules that apply to your length and propulsion.
The short version
A tinny is cheaper to buy and more expensive to own. An inflatable catamaran costs a little more on day one and then stops charging you: no trailer, no second rego, no storage bill, no ramp.

- Who am I actually buying from?
- Easy Inflatables, Avoca Beach NSW 2251, Australia. ABN 96 856 548 613. Sean is the owner and skipper, Gary Stewart handles sales on +61 2 4335 1603, Karen Matthews handles email. The boats are Australian designed; international orders ship from our Hong Kong dispatch hub so your landed price stays competitive. Phone us before you pay a cent — a real person answers.
- Is this really an Australian product?
- Yes — Australian designed and engineered on the NSW Central Coast. Manufacturing is done offshore to our spec, and international orders ship direct from our Hong Kong dispatch hub. If we routed every boat through Australia first, the freight alone would roughly double or triple your cost for the same hull.
- What do I pay, and what is not included?
- The delivery and import terms depend on your country. EU, UK, New Zealand and named Asia/Pacific lanes include duty and tax; US freight is free but US buyers pay import charges on arrival. Other destinations show their terms before payment.
- How do I pay safely?
- Card through Stripe (Visa, Mastercard, Amex, Apple Pay, Google Pay) or bank transfer. Card payments carry your bank's own dispute protection. We never ask for crypto, gift cards or payment to a personal account.
- What if it arrives damaged?
- Every boat ships fully tracked and insured door to door. Photograph the carton and the boat on arrival and email us — transit damage is claimed and replaced through us, not left with you and the courier.
- Is the warranty real outside Australia?
- Yes. The 7-year hull warranty on 1.2 mm VALMEX Heavy Plus and Orca Hypalon hulls applies wherever you are. Replacement parts are held in Australia and at our overseas hub and go out by express courier to your door.
- Is the boat actually certified?
- All Aerowave catamarans are CE certified to ISO 6185-3 and EU Directive 2013/53/EU. Certification paperwork is supplied with the boat — ask and we will send it before you order.
Frequently asked questions
- Is a tinny cheaper than an inflatable boat?
- Cheaper to buy, usually not cheaper to own. Once you add a trailer at A$1,500–3,500, annual trailer registration, bearings, tyres and storage, a tinny typically costs thousands more across five years than an inflatable catamaran that stores in a bag.
- Do I need a trailer for an inflatable catamaran?
- No. It deflates into a carry bag that fits in the boot of a mid-size SUV or on a garage shelf, and launch wheels let one person get it from the car to the water without a ramp.
- Do I still need to register an inflatable boat in Australia?
- Yes. A powered inflatable is a registrable vessel in every state, the same as a tinny. The saving is that you register one asset instead of a boat plus a trailer. Check your state maritime authority for the rules that apply to your vessel.
- How long does an inflatable boat last compared with a tinny?
- Premium VALMEX fabric has a working life of 10–12 years in Australian conditions. Our Viper hulls are 1500 GSM / 1.2mm VALMEX Heavy Plus and carry a 7-year hull warranty; AeroCat hulls are 1100 GSM / 0.9mm VALMEX with a 5-year warranty.
- Which is more stable for fishing, a tinny or an inflatable catamaran?
- A catamaran carries its buoyancy in two full-length hulls at the outer edges, so it stays flat when weight moves to one side. That is why people stand up and fish from them comfortably.
