The Island Inflatables iCAT285 paired with the Parsun 5hp 4-stroke is a very practical lightweight package for estuaries, rivers, creeks, protected coastal waters, and tender use around larger boats.
Here are the main strengths of this package:
- Excellent stability from the catamaran hull design
- Much drier ride than most conventional inflatable V-hull tenders
- Light enough to transport in a ute, SUV, caravan, or motorhome
- 5hp gives noticeably better performance than a 2.6hp or 3.5hp when loaded
- Suitable for fishing, camping access, island hopping, and exploring waterways
- Air-floor design packs down compactly while still feeling rigid underway
The claimed 4-person / 550kg capacity is realistic for sheltered water use, although performance with 4 adults and gear will be modest on a 5hp. Realistically:
- 1–2 adults: very lively and efficient
- 2 adults + camping/fishing gear: ideal setup
- 3–4 adults: workable in calm water, but slower and more sensitive to weight distribution
What makes the iCAT design different
The twin-hull catamaran layout gives several advantages over standard inflatable tenders:
- Better lateral stability at rest
- Reduced rocking while fishing or boarding
- Faster planing with smaller horsepower
- Shallower draft for beach launching
- Softer ride in short chop
The upward concave floor and spray-deflecting hull shape are genuine advantages on these boats, especially compared with cheaper flat-bottom inflatables that tend to throw spray forward.
Valmex PVC and thermo-welded seams
Using genuine Valmex PVC and thermo-welded seams is a major quality point.
Cheaper glued PVC inflatables often fail in:
- Queensland heat
- UV exposure
- Constant inflation cycles
Thermo-welded seams generally last longer and tolerate Australian conditions much better.
Expected performance with the Parsun 5hp
Typical real-world expectations:
- 1 person: planes easily and feels quick
- 2 adults: usually planes comfortably
- 3 adults: may plane depending on load and conditions
- Top speed: roughly 20–28 km/h depending on load
The 5hp is a good match because it keeps:
- weight manageable,
- fuel use low,
- and transport easy.
A bigger motor would improve speed but starts reducing the portability advantage of the package.
Things to check before buying
If purchasing new or second-hand, confirm:
- exact hull weight,
- whether the floor is drop-stitch high-pressure,
- actual packed dimensions,
- warranty coverage,
- seam warranty duration,
- and whether the Parsun includes an external fuel tank connection kit.
Also check local registration requirements in Queensland, as rules can vary depending on motor size and use.
For the type of boating many people do around places like the Pumicestone Passage, coastal estuaries, and island camping trips, this combination sits in a very useful middle ground between:
- ultra-light tender packages that struggle with load,
- and heavier alloy boats that need trailers and larger tow vehicles.
