Unfortunately, the days of cross channel 300 ton monster hovercraft are behind us, killed off by many factors - unavailability of engine servicing, increased fuel costs and finally, the end of duty free.
Nowadays, the Russian Navy ZUBR, and the US Marine LCAC's operate the world's largest hovercraft. Here in the UK, the Hovertravel AP1-88 flies the flag for the largest craft in the UK.
Down at the ‘other end’ of the scale, our original single seat ‘Snapper’ of 1998 now has a larger sibling in the shape of the Coastal-Pro, a 3-4 seat commercial craft which has been selling well to people who need a practical, safe and effective hovercraft for such uses as transport on frozen rivers, through tidal estuaries and over mudflats.
The biggest difference between the Coastal-Pro and our earlier hovercraft (the Marlin, Snapper and Mark One Coastal-Pro) is that it uses a separate lift system, which is controlled independently from the thrust system. Our smaller hovercraft use just one engine to give both lift and thrust, a system which works really well on smaller hovercraft but is redundant by the time the craft gets to 3 seats/4m or so. The Coastal-Pro is the first of these twin-engined hovercraft from BHC, but larger ones will follow.
As a result the Coastal-Pro can lift over 300kgs from a dead-start on water, and carry considerably more on land or over water without needing to stop. The earlier craft without he separate lift engine displayed some shortcomings in this area, which is why the new Coastal-Pro was born. Quite simply, larger hovercraft don’t work with a single engine and fan.
Interestingly, one company has recently released an integrated 5m hovercraft built from Carbon Fibre which they claim is capable of seating (variously!) seven to nine people or an astonishing half-tone payload – from a water start, this is a hovercraft’s biggest challenge. Of course, none of the videos actually show it doing so with 7 people on board (just big cardboard boxes in the back full of what I wonder? Air?) If you have a desire to never hear again, take a look at a video of it in action (WARNING : HEARING DAMAGE VERY LIKELY!) VIDEO
The whole design concept of a 7 seat integrated hovercraft is simply wrong. It’s a fundamental design flaw akin to building a 400bhp three wheel Ferrari or an aeroplane with one wing. This particular example is powered by a 120bhp turbocharged engine – huge complexity and noise levels fit to burst eardrums (this, from our analysis is around 96dbA at 25m, loud even for a racinghovercraft!) A carbon fibre hull is space rocket technology stuff, sure. But in hovercraft use, it’s brittle and shatters quite easily, a more useful design would be to back it up with Kevlar (something we and many others have learned from racing hovercraft over the years of competition) – on its own, it’s a poor choice.
The problems can be seen quite clearly on the promo videos, the integrated design means very poor hover height, the hovercraft never truly hovers which means the skirt is dragging and will wear out in no time. Worst case, poor hovering can mean it will catch the ground travelling sideways and stop dead or flip over…ouch!
You cannot simply ‘’scale up’ small hovercraft and expect them to work as well – there has to be limits, and this one’s been crossed - and here's the result.

Take a look at this photo - wow! No words needed!
The bottom line is that despite being a much smaller hovercraft, our Coastal-Pro (all 65bhp of it) will outperform this 5m, 120bhp offering. It’s around 1/3rd of the noise level, three times as economical, carries just as much payload, is easier to drive, more reliable (seriously – a turbocharger and extensive electronics in a saltwater environment???) – oh, and much prettier! :-)
All those years of R&D, racing, cruising, commercial work and using our own craft in every conceivable environment have given The british Hovercraft Company unmatched experience in the design and production of real, working hovercraft. No bull, no wild figures, no opinion – we’re proud to say our hovercraft perform exactly as promised in our literature and on this website
By all means, try out other hovercraft brands – then come along to us for a demo, we’ll be happy to see you and demonstrate the advantages of a clear design philosophy.
