The Polaris FIB ("Flying Inflatable Boat") is an Italian flying boat ultralight trike, that was designed and produced by Polaris Motor of Gubbio. The aircraft was introduced in the mid-1980s and remained in production until about 2014. It was supplied as a complete ready-to-fly-aircraft.[1][2]

Design and development
The FIB complies with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The FIB has a maximum gross weight of 406 kg (895 lb).[1][2]
The aircraft features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, an inflatable boat hull and a single engine in pusher configuration. The FIB has no wheeled landing gear, but as a result of customer demand it was later developed into the amphibious Polaris AM-FIB.[1]
The FIB's single surface wing is made from bolted-together aluminum tubing and covered in Dacron sailcloth. The 11.15 m (36.6 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine.[1]
The aircraft has an empty weight of 216 kg (476 lb) and a gross weight of 406 kg (895 lb), giving a useful load of 190 kg (419 lb). With full fuel of 40 litres (8.8 imp gal; 11 US gal) the payload is 161 kg (355 lb).[1][2]
The company continued to develop the design and in 2010 introduced a new hull shape to increase performance in the water and in the air.[1]
Dimitri Delemarie, writing in The World Directory of Leisure Aviation 2011-12, said of the design, "It will never win any speed records, but if there were an award for fun, it would be right up there at the top."[1]
Since 1986 Polaris Motor has sold an average of 80-100 trikes and 200 wings per year. Naturally all Polaris wings can be easily installed in other brands of trikes, with the possibility of personalization.[3]
Operational history
The FIB is used by a number of government operators, including police and coastguards.[2]
Variants
In the early 2000s the company offered a version with the same wing, but without a boat hull, using a conventional minimalist trike frame mounted on wheeled landing gear or optionally skis. Even though it did not have a boat hull it was still marketed under the FIB name.[2]
