Why buyers choose the Sovereign
The Viper 400 Sovereign is designed for owners who want a 4m inflatable platform that feels
stable at rest, rigid underfoot, and confidence-inspiring when family, mates, or fishing gear move around on board.
The twin-hull catamaran design helps reduce roll, while the 12 PSI high-pressure floor delivers a more planted, boat-like feel compared to softer or more flexible setups.
âš“ Less Roll At Rest
More confidence when boarding, fishing, or when kids and passengers move around.
🦶 Rigid Feel Underfoot
The 12 PSI drop-stitch floor feels firmer and more secure than softer inflatable floor styles.
🚀 Faster Setup
No heavy floor panels to assemble. Easier launch days and less hassle at the ramp or beach.
💰 Better Value Ownership
Key accessories are already included, reducing extra spending after purchase.
🌊 Drier, More Comfortable Ride
The twin-hull catamaran layout helps reduce spray and keeps passengers more comfortable in chop.

Why Serious Boaters Upgrade From Older SIBs
Older-style SIB and tender inflatables are excellent for portability. But when trips become longer, rougher, heavier, or more frequent,
many owners start looking for a platform that feels more stable, more rigid, and more confidence-inspiring.
What older SIB owners often want next
- More control in wind and chop
- Less flex underfoot
- Better tracking and confidence at speed
- A drier, more stable platform at rest
- Stronger materials for long-term use
What the Viper 400 Sovereign delivers
- Twin-hull catamaran stability with reduced roll
- 12 PSI drop-stitch floor for a firmer feel
- 1.2mm Valmex® 2000D material for higher abrasion confidence
- Package-ready inclusions that reduce future spend
- Australian support for setup and ownership help
Simple way to think about it:
If you need a light-duty portable tender, a traditional SIB may do the job.
If you want a serious 4m family and fishing platform where stability and rigidity matter more, the
Viper 400 Sovereign is built for that role.

Bottom line:
If you want traditional heritage in a classic sports boat format, an older Discovery-style 4m may appeal.
If you want more stability, faster setup, and a package-ready premium catamaran for real family and fishing use,
the Viper 400 Sovereign is the stronger ownership proposition.
Frequently Asked Questions
What makes the Viper 400 Sovereign different from a standard inflatable boat?
Its twin-hull catamaran design is focused on stability at rest, while the high-pressure floor gives a firmer, more rigid feel underfoot. The result is a platform that feels more confidence-inspiring for family boating and fishing.
What kind of outboard can I run?
The boat is rated for up to 30 HP. The best horsepower depends on your loading, use case, and performance goals, so contact us if you want the right setup recommendation.
Is it suitable for family boating and fishing?
Yes. This is exactly where the platform stands out. The reduced roll at rest and more stable feel make it attractive for families, anglers, and buyers stepping up from smaller or older inflatables.
Why is the package format important?
Because many buyers underestimate the extra spend required after buying a bare boat. This package helps reduce that by including the major accessories most owners want anyway.
Do you offer support after purchase?
Yes. That is part of the Easy Inflatables difference. You are not just buying a box delivered to your door. You have Australian support for product questions, setup help, and ownership guidance.
New release: This model is now available to order. Customer reviews and on-water owner media will be added to this page as genuine feedback comes in.

Stuart. P. –
okay I have only had this new boat for two weeks, so far so good. Very Stable Cat, easy to handle and feels very solid.
I’ve owned a few inflatables over the years and the Viper 400 Sovereign is easily the most stable one I’ve used. The catamaran layout really makes a difference when you’re moving around the boat. Even with a couple of people shifting weight while fishing it stays surprisingly steady.
The 12 PSI floor is much firmer than the softer air floors I’ve had before. It actually feels more like standing on a small rigid boat rather than an inflatable, which gives you a lot more confidence when launching or boarding.
Setup is also quicker than I expected. Not having heavy floor panels to assemble makes a big difference, especially if you’re launching regularly. You must het the package as it Includes the best portable air pump i have ever used.
The overall build quality feels solid and the Valmex fabric looks tough enough for long-term use. Everything about the boat gives me the impression it was designed for serious boating rather than just weekend use.
Overall very happy with it and it’s been a great upgrade from my previous Highfield inflatable. Thanks Stuart Piece, QLD
