A reply to some client questions.

added by russ on September 9, 2016 at 08:39

Copied here because many of the questions are fairly common ones!

All our craft use Briggs & Stratton Vanguard engines.  Built in Japan by Daihatsu, they are low revving four-strokes, which means decent noise levels and very good economy. Snappers use around 4-5 litres of fuel an hour, Marlins maybe 6-7 (much less than a jet ski!) They use regular UK/US pump fuel, no need for anything special.  Both will get around 2-4 hours from a fuel tank (12 litres on Snapper, and 25 on a Marlin) but of course it depends on conditions, payload, wind and the driver.

Maintenance is (in brief) as follows.

Pre-operation, check the craft over. Visually inspect skirt fix and wear, oil levels, fan condition, belt etc. Takes a couple of minutes per craft.

After a days operation in salt water, wash the craft off thoroughly with fresh water. Allow five minutes per craft.

If skirt needs maintenance, you can change each segment individually (approx. 58 on a Marlin/52 on a Snapper) and it takes just two minutes. The skirt – on water – will last a very long time, you’re likely to get well over a year from them. Sand/Mudflats/gravel obviously wear it faster but its top quality material and designed especially for us by a 'technical materials' company.

At 50 hours, change the oil, adjust tappet clearances, check fuel and air filters, replace if necessary.

How long do they last?

We have customers operating with over 600 hours on their engines, mechanically they are very robust (they are for plant/commercial use remember!) but you may replace ancillaries such as carburetors/coils etc in time. A whole new engine is only £1250.00UK so its not an expensive purchase if the worst happens. I’d certainly hope you got 5-10 years use from the craft, but of course, it depends largely how well they are looked after and the hours they clock up. We keep absolutely everything to build them (of course!) so there's nothing cannot be replaced, even the hulls which (to answer your next question) are built from GRP Fibreglass.

Wave capacity

It's difficult to be too precise about but they are all okay in a ‘chop’ – you must remember they are only small – so whatever you may be comfortable in a small boat of the same size, the hovercraft will be okay too. It’s a common question, and you may find this interesting and useful. http://britishhovercraft.com/UploadedFiles/hovercraft%20performance%20and%20information.jpg Also our FAQ page - http://britishhovercraft.com/Buy-A-Hovercraft/Frequently-Asked-Questions.aspx

Which Marlin?

For your use I’d recommend the Marlin ‘Beast’ – it has lots of extras and has more 'kerb appeeal' than the Marlin II Freestyle. The Marlin III is the best of everything, but it costs more money and isn’t really necessary for your purposes.

Marlin II : £9,500.00 - No frills, all thrills hovering!

35bhp Briggs & Stratton Engine

Yellow beacon

Bilge Pump

Jockey Seat for two

Hour meter

Kevlar reinforced floor

Internal Buoyancy foam

Limited range of colours. White hull with either blue or red trim.

 

 

 

The Beast : £11,000.00 - As driven by Jeremy Clarkson!

As above but with the additions of

37bhp Hi-Torque 'Savage' engine.

Rear 'T' Seat - more seating for up to three people.

All-round LED white light and navigation lights.

LED Headlights.

Rubber non-slip flooring.

Improved endplate rudders.

Tacho/Rev Counter.

GPS Speedo/heading compass.

Wide range of hull and secondary colours .

 

 

Marlin III : £12,500.00 - The ultimate yacht tender!

As 'The Beast' but with the following additions.

Upgraded, stiffer hull with integrated screen, revised splitter plate to reduce noise and add additional lift, larger receiver area to give improved plenum flow characteristics.

Hovercraft, The Recreational Craft Directive (RCD) & CE Marks

added by russ on November 3, 2015 at 10:25

We often get asked whether our hovercraft are 'CE' marked or not – the answer isn't quite straightforward, read on to find out.

Background

In the EU, marine vessels sold new by a manufacturer for recreational or pleasure purposes have to conform with Directive 94/25/EC, known as the Recreational Craft Directive, or RCD. This directive sets out the minimum technical and environmental standards for marine vehicles between 2.5m and 24m, ensuring they are 'suitable' for sale within the EU. The RCD was amended in 2003 by Directive 2003/44/EC which brought personal watercraft (ie Jet bikes/Jet skis) into the RCD. The directive also includes marine engines and some components. From January 2016, a new Directive, 2013/53/EU, replaces the current legislation but is basically the same and is aimed at reducing emissions.

 Exclusions

 Below is a list of vessels excluded from the RCD (taken from the RCD text.)

 craft intended solely for racing, including rowing racing boats and training rowing boats labelled as such by the manufacturer; or

 canoe and kayak, gondola or pedalo; or

 sailing surfboard; or

 powered surfboard or other similar powered craft

 original, and individual replica of a historical craft designed before 1950, built predominantly with the original materials and labelled as such by the manufacturer; or

 experimental craft, provided it is not subsequently placed on the Community market; or

 craft built for own use, provided it is not subsequently placed on the Community market during a period of five years; or

 craft specifically intended to be crewed and to carry passengers for commercial purposes, regardless of the number of passengers or

 submersible; or

 air cushion vehicle; or

 hydrofoil.

See it down there second from the bottom? Hovercraft are air-cushion vehicles (ACV.) So, in short – neither we, nor any other manufacturer can CE mark our hovercraft under the RCD, as ACV's are not eligible. Having checked the forthcoming legislation, we can confirm that they remain excluded from the new 2013/53/EU directive as well.

 Options

Two years back, BHC approached the European authorities and opened a dialogue aimed at either including ACV's or allowing us to voluntarily claim compliance and plate our craft accordingly. However, the ACV market is too small to interest Europe and we were refused. So, we looked into other directives, the only one of which seemed at all relevant was the Machinery Directive 2006/42/EC. Again, following extensive discussions, the answer was a 'no.'

We lobbied the EU to include ACV's in the new legislation due to the growing market – but as stated above, ACV's remain excluded.

 So where does that leave us?

A number of boat builders have told us that we're lucky that we do not have to comply with the RCD and the inevitable administration that goes with it. However, our ambition for the hovercraft industry is such that we're looking at the big picture and the long term growth of both the industry and our own business. We've certainly lost a few sales over the years due to the fact we cannot claim compliance with the RCD, but generally this has been due to the misunderstanding that the craft should be compliant.

However, with very few exceptions, and in all the main areas of safety, our craft do comply with the standards of the RCD. The only area we may struggle is with the stipulated noise levels, marginal on the Snapper & Marlin but the Coastal-Pro is comfortably within limits.

So what's that CE plate I see on the dashboard then? 

Although – as established – we cannot claim compliance with the RCD, ACV's do still need to comply with the standards of the Electromagnetic Compatibility Directive 2004/108/EC. This directive basically confirms that a product sold within the EU is not causing excessive electromagnetic interference, nor is effected by the same. So, back in 2013, we put our craft through the necessary tests and compiled a conformance file. Following a meeting with Kent Trading Standards, we started to affix a compliance plate to all our craft.

Are BHC craft built to a standard? 

Of course! Back in 2012, we approached the MCA to introduce a set of standards for small hovercraft. Initially rebuffed, we eventually got our way, and together with Griffon Hoverwork of Southampton, we established a manufacturers association and got the MCA to the table to start work on the 'Hovercraft Code of Practice.' Three years, many hours, miles and meetings later and the code is due to be introduced anytime soon (it's currently going through public consultation) and sets out standards for small craft up to 24m in length. It's our fervent hope that the legislation will be adopted by other countries in due course.

All our craft are built to the standards of the HcoP and marked accordingly alongside the conformity statement for 2004/108/EC and this – in truth – is a more relevant build standard than the generic RCD could hope to provide. 

Conclusion

Hopefully, this document will explain what is possible, why hovercraft cannot be CE Marked, what standards BHC craft meet and what we've done to establish the build quality of our products.To the best of our knowledge, BHC manufacture the only hovercraft that conform to any formal standards - at least nobody else claims compliance with the HcoP or 2004/108/EC. We were the company that started the ball rolling to introduce the HcoP, we've discussed voluntary inclusion into the RCD , explored options and as such, we believe our products conform with all existing legislation and exceed the industry standards of the HcoP.

British Hovercraft Company - Play Day for friends and family!

added by russ on June 23, 2015 at 09:12

It's been a pretty mental few months now and at times, the order book has rather outstripped production! But the team working in production have risen to the task brilliantly - working, quickly and efficiently and putting extra hours in as required to make sure that customer orders have been completed on time - we're are genuinely grateful for their efforts.

As a bit of a thank you, we decided to throw another one of our 'play days' where we invite the familes and friends to come along for a drive in the safety of our demo track in Sandwich. Some vigourous work with the mower, rakes and water pump (to refill the bone dry pond!) gave us a useable track, Emma's new exhibition trailer (of which she is rediculously proud and excited!) was pressed into use as the corporate centre (we're not quite Red Bull Formula One yet!) and a huge BBQ thrown together from an empty acetone drum, base made from an old trailer chassis and off-cuts of hovercraft fan ducts providing the grill!

All in all, a quick and dirty bit or organisation which worked out just great. I was responsible for the weather (which was gorgeous) and we got really lucky when a stunt plane turned up and put a spectacular display on for the show in the next field over... result! Nobody died of food poisoning, dozens of people drove a hover for the first time and the kids and dogs were completely exhausted when we finished up around 6pm.

A great day, thanks so much to all our staff for their hard work, and friends and family for coming along and helping out.

Here's a few photographs from the day, mostly courtesy of my Auntie Brenda!

 

 Awesome show - Pitt Special?

 The peace and tranquility of an English summers day!

 

I taught a lot of people to drive... successfully too! :-)

Gary soaking the girls. 6 years old and they love it...2 years old and they hate it!

Your never too old to try it - right uncle?

Emma's trailer..next stop the vinyl wrap ready for some shows.

And you're never too young either - 10 year old Kai drove the Snapper like a boss! ("Daaaad? Can I race one next year....?")

Carbon Fibre Integrated Hovercraft....no, not really the answer!

added by russ on May 28, 2015 at 10:23

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.

Meanwhile...put your fingers in your ears, turn down the volume on your PC and and play THIS VIDEO!

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.

Quiet Hovercraft! Our Coastal-Pro Noise Test Results.

added by Emma on January 26, 2015 at 05:52

Noise is the biggest challenge faced by hovercraft designers and builders. In the last year we've been conducting a significant project to develop new, more quiet hovercraft, and the Coastal-Pro is the first to benefit from the results.

Much of the credit for this work must go to Keith Oakley. Keith has been involved with hovercraft as a passionate enthusiast for a very long time and over the last few years has tested over 150 hovercraft for their noise signatures. Using the information gained from this, we've worked together to improve noise levels using his knowledge together with our experience and engineering facilities. Keith's work is hugely respected within the hovercraft community - what he wants to achieve is a greater acceptance for hovercraft in both commercial and recreational applications, and to have him working so closely with us to achieve this is a fabulous opportunity for us. Basically (without giving away commercial secrets!) there are about ten significant factors which are responsible for the noise. Some improvements are fairly straightforward and generally understood  such as bigger ducts and slower fans. But Keith's research has also identified some more subtle factors which when addressed as part of an overall design,  contribute significant reductions in overall noise levels.  

We knew the Coastal-Pro was good but we had only had a chance to run some rough tests. What we were keen to do was to thoroughly test it for 'flyby' noise - the most relevant test for a dynamic machine (as opposed to a static test) but had to wait for a calm day without wind to skew the results.

The outcome was extremely satisfying. After averaging three runs, maximum noise at full power measured at 25m was 78dbA. However, at cruising speed (approximately 20 knots) the noise was just 74dbA. This is way down on traditional hovercraft noise levels and we believe it is demonstrably the quietest commercially built hovercraft available anywhere in Europe. In real terms, if you're standing on a river bank and a Coastal-Pro passes by, the noise simply isn't unacceptable or offensive.

This is just the first application of the project results to our range of craft, and in some ways the easiest to apply. But our 'crusade' continues, and we promise more results in due course. Make sure you 'like' our Facebook page and you'll be the first to hear about them!

Hovercraft Torture Testing - Torrential Rain, High Winds & Salt Water!

added by russ on October 7, 2014 at 08:15

What were we thinking? It was Carl's fault, he wanted to spend his birthday out on his hover. The weather forecast was for 25mph gusts and torrential rain. For once they got it right. Together with 3 Marlin II's, it was also the first time out in such terrible conditions for the new Coastal-Pro MACV.

We returned some three hours and 20 miles later very cold, and soaked through to the unmentionables - but we did prove that our craft can take pretty much anything you can throw at them!

Take a look at the video, and leave a comment/like it (if you do!)

Flying Fish Marlin III, Coastal-Pro and BBV500 hovercraft are ready for marine usage. Days like this teach you plenty and having experienced many of them over the years, we know our hovercraft perform extremely well even in the worst conditions.

The Coastal-Pro is the new 2014 3-4 Seat Hovercraft from Flying Fish which is designed for the commercial market. With Hovercraft legislation having completely changed in 2014, small hovercraft can now be used for a huge range of intertidal and shallow water applications such as water sampling, nearshore survey,Water Quality Sampling (Benthic, WFD, Plankton sampling,) Intertidal Fish Stock Monitoring (Seine and Fyke netting) Ecological Survey,Tidal Flow Monitoring,Accoustic Survey (Hydrophone) Bank Erosion Surveys, Bridge and Structural Surveys, wildlife Monitoring such as bird, seal & cetacean and habitat survey.
One day, who knows, maybe the Coastguard will finally see sense and buy some hovercraft for Mud Rescue!

Hovercraft Cruises - Date for the diary late 2014.

added by russ on October 2, 2014 at 06:38

Amongst the many 'hovercraft hats' I wear is the slightly dodgy sounding 'cruising director' for Hovercraft Club of Great Britain events.

Following last night's South East branch meeting, we've put together some dates for some late season cruises as below.

As usual - all hovercraft are welcome as long as they are reliable and safe in an uncontrolled (and demanding) marine environment. These are club events, not strictly Flying Fish ones but you'll need to join the HCGB to come along.

Saturday 4th October 2014 - Launching Gillingham Strand

Saturday 1st November - Long Reach Ski Club

Saturday 29th November - Long Reach Ski Club

Friday 26th December - Boxing Day cruise. Probabaly a 'round Thanet' keep-warm, pub-based cruise launching from Sandwich, Kent.

All dates are weather dependant - please contact me for more details of you'd like to come along.

The Medway & Swale Boating Association (MSBA) Meeting at Kent Boat & Ski Club

added by russ on September 3, 2014 at 09:10

 

 

It's fair to say I live and breathe hovercraft! Apart from running Flying Fish alongside my wife Emma, I'm also secretary of Hovercraft Manufacturers Association, Chairman of SE branch of Hovercraft Club of Great Britain (HCGB), and 'Cruising Director' for the HCGB (which frankly, sounds a bit weird.) I also race in the national championships and still thoroughly enjoy taking a hovercraft out for a spin on my favourite patch - the River Medway & Swale.

 So it was with some interest that I stumbled across the Medway & Swale Boating Association (MSBA) a little while ago.

To paraphrase their aims (from their website) :  “To promote and protect all waterborne sports and pastimes on the tidal Medway and Swale.”

The hovercraft community has been using Medway and Swale for a very long time, why wouldn’t we be part of the MSBA for the modest joining fee?  If you've seen any of my videos from Hoverclub events, you'll understand why - it's very tidal, loads of mudflats and shallow water to explore - and an amazing history with Napoleonic forts and WWI shipwrecks to visit.

So I decided to join up on behalf of the Hovercraft Club of Great Britain. As I'm involved with organising club events 8-10 times  a year, which usually launch into the Swale at the Long reach Ski Club, I felt it was important that our sport was represented within this new Organsiation.

Last night, along with Carl & Geoff, two of our growing list of active local enthusiasts, we went along to the Kent Boat & WaterSki club at Cuxton to see what it's all about. We were made very welcome and met loads of interesting folks who work and play on the Medway & Swale. The MSBA looks a very valuable resource and a great way of ensuring that the river is used responsibly - but that we water users don’t see more of our rights diminish as a result of increasing legislation and the 'environmental takeover' of the seashores. It was an interesting meeting and I'm pleased the Hoverclub now has a representation on it.

One issue was the contents of some previous minutes which indicated that reports were being made to Peel Ports (the harbour authorities) of illegal hovercraft launches from Gillingham Strand. I had to question this as the minutes seemed to indicated that the MSBA agreed with these complaints. The feller who's made these reports is a member and has my respect for saying 'that was me' and explaining why he made these reports. Basically, his position is that as somebody who runs a business on the Medway, he's sick of seeing so many laws and rules flouted by water users  and not being enforced. I can see that - if you're going to have rules, then enforce them. We explained that hovercraft are not PWC's - legally they are boats and the MCA categorises them as such and are therefore entirely legal to launch at Gillingham Strand. Further discussion centred on usage and speed limits - explaining that hovercraft create less wash at speeds over approx 8 knots which is the approximate speed where the hull is completely out of the water, resulting in no wash! In our experience, most harbour masters understand that and allow a small amount of leeway on the tightest speed limits - after all most speed  limits are made largely to prevent dangerous wash in busy and confined moorings.

And one point to remember. In the UK, you have a common law right to navigate on tidal waters. Restrictions may be made, permissions may be required, but you do have that right and it cannot be removed with a byelaw. Just remember that if you are ever told otherwise.

Bearing in mind that there have been literally hundreds of launches and hovercraft operating in the areas, to the best of my knowledge there have been absolutely no accidents involving hovercraft, very few breakdowns or recoveries and to the best of my knowledge and no prosecutions or charges brought against owners.

Statistically, hovercraft are the safest  means of passenger transport and its to my own personal delight that this amazing record also applies to the recreational hovercraft.

Hovercraft have considerable environmental advantages compared to other powered vessels.

  • They do not pollute the water like a PWC or boats - the exhaust is vented to atmosphere not into the water.
  • Recreational craft achieve approximately 20mpg, so use much less fuel than a boat of equivalent size.
  • They do not create any wash so they cause no damage to river banks
  • They have no protrusions underwater, so cannot strike marine mammals such as porpoises, dolphins or manatees. The lack of propeller  or jetdrive also means they do not damage the seabed in shallow water.
  • They exert 75 times less pressure on the ground than 12" of tide, or 100 times less than a man walking.

Hovercraft do have a rep for being noisy but modern craft using small commercial spec air-cooled engines are around a quarter of the noise of earlier two-stroke models.  The noise is directional in nature and due to the low frequency dies away very quickly. At 100m it is not any more intrusive than many other water vehicles.

One key point is that recreational hovercraft use tends to be 'get in and go' and are used in much the same manner as many people use a rib or small boat.  Club events are usually organised so that the group travels to an objective. Our last four hovercraft club cruises this year covered 23/32/50 and 45 miles - we don’t just go round and round in circles near the shore.

Being part of the Medway & Swale Boating Association looks to me like it will be a valuable and useful part of organising events and continuing the growth of the Hovercraft Club of Great Britain - and our thanks for allowing us to be part of it.

We're back racing in two weeks.

added by russ on August 29, 2014 at 05:40

Well, its that time of the year again!

Our new Cobra Formula 2 Hovercraft is pretty much ready, so we're off racing at Towcester Race Course, Northampton, in two weeks time. This time, we've dropped the stupidly-powerful-but-bloody-heavy GSXR600 engine in favour of a 440cc Snowmobile Engine from a 2007 Lynx MXZ Z440. Roughly 100bhp but 32kgs... should be quick but it'll take a lot of sorting out and setting up. 

We'll also have the new Coastal-Pro there, so if you'd like tocome along and see it, you'll be very welcome.

Just to whet your appetite, here's a taster - our Cobra F2 racing from Prudhomat, France in 2013.
