Design and Construction
The Adventure Island's core is a rotomolded polyethylene hull carrying larger amas with reverse wave-piercing bows, and those amas tuck parallel against the hull the larger amas tuck parallel against the rotomolded polyethylene hull for docking. Folding ama arms snap onto the hull in an instant and can be extended or folded while underway, giving the boat a self-limiting character that makes it nearly impossible to flip. When it catches too much wind, the hull leans and buries the downwind outrigger, automatically slowing and turning safely upwind. A pivoting centerboard rather than a daggerboard prevents lateral slip, and the 130-pound main hull is light enough to hoist with the plug-in wheelie cart.
Rig and Handling
The sailing rig uses a free-standing rotating mast around which a fully-battened, roller-furling sail is wrapped, and the manufacturer describes a roller-furling, vertically battened mainsail providing lift. Period tests note a 15-foot mast with a 54.5-square-foot sail on earlier configurations, while later assessment describes a stiffer two-piece carbon-fiber mast carrying more sail area, with Harken hardware, Delrin plastic bearings at the mast base, and Spectra cord rudder lines. A tester working the two lines for the sail with one hand and controlling the rudder with the other could go from full sail to zero in about five seconds. The Mirage Adventure is the fastest kayak in the Hobie lineup, and under pedal-and-sail combination testers flew along at up to seven knots, averaging four or five, and pointed close to the breeze at up to 5 knots in 7 to 10 knots of wind.
Drive and Performance
Beyond the sail, the boat carries a forward and reversing MirageDrive 180 with Glide Technology and patented Kick-Up Fins, offering paddle-free locomotion when wind dies, and it comes standard with ST Fins. The hull's flexible polyethylene construction undulates over small waves, and testers found that flexibility helps it cope with larger waves and keeps ama bows from burying too quickly when running at speed. The boat is not dry, though — in any breeze or chop a tester advised wearing a bathing suit — and the manufacturer positions it as an exceptional bluewater-capable fishing platform with built-in rod holders.
Accommodations and Equipment
On deck, multiple hatches and on-deck stowage encourage multi-day adventures, with three hatches counted in one review. The Vantage CT seating adjusts angle of recline and height quickly and easily, and testers described those seats as more elevated than predecessors, lightweight, quick-drying, and infinitely adjustable with good lumbar support. An accessory trampoline kit adds walk-around space between amas, and a cup holder rounds out the cockpit creature comforts.
Known Issues
The rudder-control lever drew a tester's criticism as stiff with little mechanical advantage, working best when a setting is picked and left alone for a while.
The Verdict
The Adventure Island is a clever fusion of sit-on-top kayak and trimaran, trading cabin comfort for an open, pedal-or-sail versatility that few small craft match. Its rotomolded hull and snap-on amas make it forgiving and portable, while the free-standing furling rig and MirageDrive give a solo sailor redundant ways to make way. Wet and rudder-stiff it may be, but it remains an approachable, nearly unflippable coastal and bluewater fishing companion.
Pros
- Nearly impossible to flip due to self-limiting outrigger design

- Pedal drive plus furling sail for wind-independent travel
- Quick-adjusting elevated Vantage CT seating for multi-day use
Cons
- Stiff rudder-control lever with little mechanical advantage
- Not a dry boat in breeze or chop
- Open sit-on-top layout with no enclosed shelter
