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!

The Coastal-Pro - designed with rescue hovercraft in mind.

added by russ on October 9, 2014 at 04:33

The new Coastal-Pro from Flying Fish is aimed squarely at utility/commercial and rescue operations.

Hovercraft can travel over pretty much *any* surface, but the key to their potential as rescue craft lies in their ability to effortlessly traverse

*Shallow Water* where conventional vessels cannot approach a victim or vessel.

*Mud Rescue* where traditional methods are almost farcical ('mud shoes' and dragging a sled/stretcher together with rope and equipment.)

*Ice Rescue* - The perfect vessel as a hovercraft spreads its weight over the entire area it covers, meaning less chance of ice breakage. Can also travel over water should ice break.

Twin engines give precise control and an ability to travel very slowly whilst retaining maximum lift and ground clearance. Larger size gives more space and load carrying capacity but retains excellent manoeuverability and ability to access tight areas.

We've previously supplied Marlin & Coastal-Pro hovercraft to countries such as Finland & Hungary for rescue operations, as well as assisting State Emergency Services in Australia during the  2010 Queensland Floods. So if your rescue organsation is looking for a viable and cost effective alternative to current methods, please call us!

 

 

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!

COASTAL TRANSIT SERVICES - A NEW SERVICE FOR BUSINESSES WORKING IN INTERTIDAL AREAS.

added by russ on September 23, 2014 at 08:01

Survey and monitoring operations in intertidal areas have always represented a challenge. At best walking across tidal flats carrying heavy equipment can be hard, slow, dirty work -  at worst, soft mud and fast tides can make it a lethal business.

The Solution

However - a practical and cost-effective solution is finally available. In June this year, the regulations governing the use of small hovercraft for UK commercial operations were substantially revised, after UK manufacturers Flying Fish Hovercraft & Griffon Hoverwork spent two years working with the MCA to produce a 'Hovercraft Code of Practice' (HCoP).

This means that small hovercraft can be used in limited commercial operations without any requirement for coding, as long as it is built, equipped and operated in accordance with the HCoP. To that end, Flying Fish designed and produced a new model of hovercraft specifically aimed at intertidal marine work such as sampling, survey and ecological monitoring in environmentally sensitive areas such as estuaries, foreshores and mudflats.  

The MACV can travel over any surface. Any depth of water, mudflats and sand can be traversed in complete safety with up to 4 persons on board. Noise levels and economy are exceptional, and the MACV has zero environment impact as it exerts less pressure on the ground than 12" of tide. Research as shown that birds are no more disturbed by the craft than any other vessel.  The speed of the MACV means that projects can be completed much more quickly and 'between the tide' times are extended without risk, saving time and money.

Cost Effective Rental

In response to adoption of the new code, Flying Fish have launched a new service 'Coastal Transit Services' to provide MACV craft and skippers on either long or short term hire anywhere in the UK or EU. Hire costs may vary based on location and length of deployment, but are quite modest in the region of £700.00/day including skipper and fuel  As manufacturers, CTS have full support and backup for their service, and skippers are all qualified to required standards as well as having a minimum of 5 years experience in small craft.

Recent work has been undertaken with a survey company on the tidal Thames, and a University in the west country with both organisations declaring themselves delighted with the comfort, safety and cost savings.

MACV's are also available for sale to organisations with more regular work in intertidal areas. Built and equipped to MCA specification, together with manufacturers conformity statement from £25,000.00+VAT.
