C.    PARTICULARS - HOVERTREK

 

The Hovertrek is the culmination of Neoteric's 40 years of experience in light hovercraft development and engineering.  Its design embodies all of the advantages and advances Neoteric has innovated—side-by-side seating, fully enclosed cabin, highly developed reverse thrust for braking and maneuverability, more cockpit room, increased thrust and low weight. Great efforts have been taken to ensure Hovertrek's aesthetically appealing design. Engineered to satisfy expectations and give value for money, Hovertrek is the 21st century light hovercraft.
