Hov Pod Hovercraft Rescues Kayaker in New Zealand
Auckland Airport, New Zealand, rescued a kayaker who got into difficulties in early January 2010, with their Hov Pod Rescue Hovercraft. Rescue Boats in the area were unable to reach the victim, so the Airport deployed their Hov Pod to help save the kayaker.
Excerpt taken from: Auckland Airport Hov Pod Rescues Kayaker
"When a kayaker became exhausted and stranded on mud flats near Puketutu Island, the Auckland Airport hovercraft rescued her
3 January 2010 - Auckland Airport
A hovercraft from Auckland Airport has been used to rescue an exhausted kayaker. Around 3 o'clock this afternoon Coastguard received a call from a woman stuck on mud flats near Puketutu Island in the Manukau Harbour. Coastguard sent their boat to the scene but the closest it could get to the kayaker was still 800 metres away. So the hovercraft from nearby Auckland Airport was called to rescue the exhausted paddler.
Coastguard also reports a busy day elsewhere, with a vessel filling with water after hitting a rock in the Bay of Islands and a jet ski rescue at Raglan."

Purchasing a Hovercraft? Intro Series #4
Intro To Hovercraft Purchasing #4
If purchasing a hovercraft for the first time, there are quite a few items you need to be aware of in order to determine the right vehicle for your needs. This 4th and final issue of our Intro to Hovercraft series will guide you step by step through the important points to consider to ensure your safety, complete satisfaction and that the hovercraft you choose is durable & strong.
Many issues affect Hovercraft performance, just as they do a boat, aeroplane or helicopter. Since the Hovercraft is partly all three of these vehicles, it is important that you consider a range of factors from durability, performance and safety, to the type of hovercraft skirts and hull materials used in construction. In addition, operational considerations and terms such as "ploughing-in" and "getting over the hump" should be understood and the manufacturer questioned on these items, before choosing the model and brand that will best fit you.
OTHER HOVERCRAFT CONSIDERATIONS
Workmanship and Craft Quality
Check how the vehicle is made in general. Is the Hovercraft constructed of GRP (fibreglass), has GRP chop strand mat been used, or quadraxial mat? Quadraxial mat is much stronger and forgiving than chop strand fibreglass. A whack with a mallet shouldn’t offend. GRP when new nearly always looks great but if not made by experts in a controlled environment it will soon suffer from many hidden problems. Ask to see an older model to check the quality of the GRP, which can crack and delaminate after 6 months. An immaculate looking fibreglass craft on day one can, after 6 months, look very forlorn. GRP repairs are costly.
If not Fibreglass, what is the Hovercraft made of and what are the advantages or disadvantages of an alternative material. HDPE (High Denisty PolyEthylene) is the same material used in Kayaks and increasing runabouts. It is a wonderful option and upgrade to Fibreglass for a vehicle that is meant for use on land AND water.
-- The Hov Pod is made of HDPE - independantly buoyant, flexible, UV stabilised and extremely hardy, we invite customers to strike the Hov Pod hull with a baseball bat. I doubt many other manufacturers would encourage this practice. After many years of Fibreglass production and some costly personal experinces, no Hovercraft I own will ever be made out of Fibreglass again.
Bumper Protection System
Does the craft have a really solid bumper protection system? Can you give the impact areas on the side and bottom of the craft good hard whacks with a mallet? Can you sit on the side quite happily without breaking it?
-- The Hov Pod is re-inforced with aluminium and Rubber bumpers, Aluminium impact sheets, runners and wear bolts.
Ease of use

Ease of use
On Water:
- Can the craft be used in the conditions you intend to use it? (On water, sit on the side, climb in, climb out)
- Will it topple over?
- Does it plough in?
- Will it float?
- What weight can it lift in on water-starts?
- Has any government provided safety certification?
- Can you perform an emergency stop?
- Can you maintain control when doing this?
- Does the craft travel in a straight line?
- Do you have to throw your weight when cornering? (many craft will not turn unless you move your weight to the side of the craft).
- Is driving instinctive to use with handlebars and throttle? (or are complex joysticks and elevator controls needed to use the craft?)
- Can the hovercraft be used safely on land or is it likely to disintegrate?
-- The Hov Pod design was deliberately focused on product quality, ease of use, ease of servicing, safe to operate, reliable, durable and most importantly - fun! To understand our marketing approach, I recommend you read the Hov Pod Design Philosophy Document. Stretching the dollar is important for everyone, but so too is value for money, no one wants to spend thousands on a vehicle that is unsafe or difficult to repair.
Hov Pods are extremely easy to drive, similar to a motorcycle, and fantastic fun. In demonstrations, we can usually hand over the controls to a person after 5 - 10 minutes tuition. Hov Pods were specifically designed for marine leisure and commercial use and have many features that you will not find on other hovercraft. Many Hovercraft owners choose other vehicles before the Hov Pod, only to return after months or years of frustration.
Thank You For Your Time!
Thank you for reading our Introduction to Hovercraft Series. We hope you will arrange a demo of the Hov Pod for yourself soon. Let one of our local Dealers show you the superior features of the Hov Pod so you may determine for yourself: why the Hov Pod remains arguably the best leisure hovercraft available anywhere in the world today.
To arrange your own personal demo today, email sales@hovpod.com.au in Australia or sales@myhovpod.com worldwide. For more information, please visit our website:

In addition, operational considerations and terms such as "ploughing-in" and "getting over the hump" should be understood and the manufacturer questioned on these items, before choosing the model and brand that will best fit you.
PERFORMANCE Continued.
Skirts!
Occasionally, hovercraft skirts may get damaged so you need to know how to replace a skirt, how expensive and how difficult the job will be. There are generally two approaches to skirt design, a single skirt, that wraps the entire craft or a segmented skirt design. Single skirts tend to cost less for a complete craft-wide replacement, however replacing one single segment on a segmented skirt, is a lot less expensive than a whole wingle skirt. Additionally, damage to a single skirt may require replacing the entire skirt, while again, only the segment in question would need to be replaced on a segmented skirt. Replacing an entire skirt can be a big job and usually means recovering the whole vehicle back to a workshop or garage, while many segmented skirts can be replaced in the field.
-- The Hov Pod has 65 different segments for damage limitation, so rather than having to replace the whole skirt if damaged, at great cost, you simply replace the damaged segment. Naturally you will wish to go exploring with your hovercraft, but need to get home safely, so having a few spare skirt segments handy is a good idea and only takes a minute to change each segment.
Skirt Strength
Skirt strength is dependant on the material used and the way a skirt attaches to the Hovercraft. Rips and holes torn in a skirt, combined with UV degradation can quickly destroy a seemingly good skirt. Should this happen while touring the countryside, you will want to ensure your Hovercraft is capable of getting you home.
--The Hov Pod uses a Polyurethane / Nylon material for excellent wear, UV and salt-water protection. We invite customers to try tear this material during demonstrations - no one has managed in over one year - we even cut it with scissors to give them an easy start!! The Hov Pod in tests has operated with up to 25% of the skirts missing. The careful design of the skirts also means that in normal use the Hov Pod generates little to no spray and the drive and passenger can stay virtually dry.
Hull Material
We touched on the importance of a good quality hull in our last segment, with regard to stopping on land. However even in general use, the impact resistance of your Hovercraft Hull is vitally important to keeping you safe, dry and most importantly - afloat. Glass fibre hovercraft not fitted with bumper bars can disintegrate on impact with stationary objects; cracked GRP damage can be difficult and quite costly to repair. It is possible that Glass fibre hovercraft hull's can literally fall apart after hitting a wave, because of the difference in design form a standard boat hull to a Hovecrraft hull and skirt system.
-- The Hov Pod hull is unique, manufactured from HDPE (High Density Polyethylene). HDPE has been used in the past to construct Formula 1 Race crash barriers and artificial joints; it is extremely strong, impact resistant and extremely buoyant. We invite customers to strike our hulls with a baseball bat to test their sturdiness. Try asking to do this with other brands of Hovercraft! Hov Pods are designed to withstand accidents when they occur, protected by an aluminium and rubber bumper strip which helps to further minimise damage to the craft. Just to make sure and because we really do like using Hov Pods on land, we also fit aluminium impact sheets, aluminium runners and wear bolts on the underside of the Hov Pod for durability and support whilst coming to rest on firm ground.
"Ploughing in"
This is a term used in the industry to describe a problem where a hovercraft suddenly stops, due to the nose of the craft dipping into water - as anyone knows, sudden stopping or deceleration will cause passengers and driver to part company with a vehicle. This can happen through excess speed, lack of appropriate lift or one of many possible scenario's usually linked to operator error.
-- The Hov Pod has been designed to overcome the problem of "plough in" - in fact, we recommend suddenly stopping in the Hov Pod should you need to, at which point the Hov Pod will operate more like a boat slowing in the water rather than a Hovercraft. The Hov Pod has never ploughed in, though we continue to hear of incidents where other hovercraft have suffered this problem, sometimes with quite serious consequences. It's simple controls avoid the opportunity for user error.
Transportation
Once you have a Hovercraft, you now need to get it to your place of recreation. Most standard trailers will not do, while cheaper, they require either two, three or four people to back breakingly lift the craft off and on the trailer. Fly-on Fly-off is sometimes offered as an option but in reality is not as simple as it sounds, since Hovercraft tend to drift downhill with gravity. If your trailer is not situated on a perfectly flat location, getting it on or off a trailer can become quite tedious.
-- The Hov Pod can be supplied with a fully galvanised custom designed trailer made by an approved trailer manufacturer. For safety this trailer is designed for single person operation - a big bonus for Search and Rescue (SAR) organisations. The Hov Pod trailer utilises 4 rubber coated rollers (to protect the hull and stop that annoying banging when trailering) and a simple winch mechanism to gently unload or reload the Hov Pod in about one (1) minute.
Safety
Good safety design is no accident. Safety is a very important aspect of design for the leisure and commercial market. Just as with any other quality vehicle (boat, car, plane), that you would consider putting your family into, your Hovercraft should have reasonable and sufficient safety mechanisms in place. Consider sealed batteries and ventilated fuel tanks for example. Properly waterproofed and marine standard electronics. Marinised engines, aluminium parts for marine use. Even something as simple as fan guards should be stock standard on a Hovercraft - the majority of hovercraft manufacturers do not fit these.
-- The Hov Pod has undergone extensive development wih safety as a key factor. We fit a front and rear guard to the fan assembly - who in their right mind wouldn’t? Sealed batteries, electronics, ventilated fuel tanks, marine grade wiring and operating parts. Designed to manage air-flow and avoid "ploughing in." Finally, one of the largest safety factors inherent in the Hov Pod is the Hov Pod's ease of use. Don't believe me? Please visit our website for pictures of children as young as Three (3) years of age driving the Hov Pod (with adult supervision of course). The Hov Pod only needs fingertip control, no need to shift your weight to turn corners! With CAD and CNC designed parts, the Hov Pod has gone through a full governmental certification.
So we come to the end of our 3rd part in the Introduction to Hovercraft Purchasing series! I hope it has been informative!! Keep an eye out for the next in this four part introduction to Hovercraft series.

Purchasing a Hovercraft? Intro Series #2
Intro To Hovercraft Purchasing #2
If purchasing a hovercraft for the first time, there are quite a few items you need to be aware of in order to determine the right vehicle for your needs. This 2nd issue of our four (4) part series will guide you step by step through the important points to consider to ensure your safety, complete satisfaction and that the hovercraft you choose is durable & strong.
Many issues affect Hovercraft performance, just as they do a boat, aeroplane or helicopter. Since the Hovercraft is partly all three of these vehicles, it is important that you consider a range of factors from durability, performance and safety, to the type of hovercraft skirts and hull materials used in construction. In addition, operational considerations and terms such as "ploughing-in" and "getting over the hump" should be understood and the manufacturer questioned on these items, before choosing the model and brand that will best fit you.
Lets Talk Engines!
Firstly, what sort of engine do I want in a Hovercraft? Remember in the first part of this series, we discussed that Hovercraft are part aeroplane, part boat, part helicopter? Well, when it comes to engines, just like in an aeroplane, weight matters! As you decrease the weight of an engine, without decreasing power, generally speaking price increases dramatically. Therefore many Hovercraft are built with pre-loved engines. 'Re-fitted', 'reconditioned', ‘used’ automobile engines or small commercial engines that need to be re-tuned and upgraded to generate sufficient power and therefore are prone to long term failure and overstressing of components. Either that, or your Hovercraft has to be built especially large to allow for a smaller engine to provide an equivalent lift (by spreading the downward airflow over a larger distance, less power is possible). This approach however does make for cumbersome and hard to trailer Hovercraft. Another concern is how effectively you can marinise and protect an engine that was not built for water use such as a car engine.
-- The Hov Pod uses highly reliable, brand new, high power-to-weight, marinised Weber & Rotax engines proven by many years use in the snowmobile, ATV, Jetboat and microlight industries. Hov Pod locates these engines under a uniquely designed engine cover system that offers excellent protection from the elements yet is very quick and easy to remove (approx 15 seconds). The Hov Pod engines have been put through their paces for hundreds of hours in very harsh marine conditions in climates such as Africa, Australia, The Caribbean, and the Middle East.
One Engine or Two?
Many hovercraft use two engines, one for thrust, one for lift. Lift engines are generally placed in front of the driver - This means that all the fumes and noise comes straight at the driver and the first wave that hits your Hovercraft may simply swamp the engine, thereby causing lift failure or the Hovercraft to 'plough in' - I hope that Hovercraft Floats! (don't be fooled, many don't).
But lets pretend that the Lift engine doesn't cause fume, or safety issues, now I'm back to my Helicopter flying days as I navigate a myriad of controls adjusting my lift engine speed and my thrust engine speed in order to drive the Hovercraft. Not only is it not simple, it's potentially expensive as I have to maintain two separate engines, fans and associated drive mechanism's.
-- The Hov Pod has only one engine for lift and thrust - since it is far easier and safer to coordinate one set of controls, more cost effective to service one engine, plus the noise footprint is lowered with only one engine. With only one engine to stow, the Hov Pod was deliberately designed without a gearbox assembly, allowing the engine to sit much lower in the craft, thereby lowering the centre of gravity, reducing the tendency to roll (I have seen other craft literally roll over in a simple low speed turn), and providing much greater ease of control. A lower engine also minimises airflow disturbance to the fan - clear airflow results in greater efficiency.
PERFORMANCE
Stopping on Land
Hovercraft should be considered as much a land-based vehicles as it is a water-based vehicle; stopping on a small rock shouldn’t cause the floor to crack, since cracks let in water. Most hovercraft have a single thin skin floor, made from glass fibre. It's important to find out just how durable your hovercraft is going to be, or you risk purchasing a complicated airboat and not a Hovercraft.
-- The Hov Pod hull is unique, manufactured from HDPE (High Density PolyEthylene). HDPE has been used to construct Formula 1 Race crash barriers and artificial joints; it is extremely strong, impact resistant and extremely buoyant. (One day, all hovercraft manufacturers will use this material). We add aluminium runners, impact sheets and wear bolts to protect the craft from the inevitable knocks that occasionally occur. There have even been Hov Pods in multiple car accidents where all cars and trailer have been written off, but the Hov Pod has been able to fly away.
Stopping on Water?
Apparently, many manufacturers tell their clients to avoid doing this. Believe it or not, some Hovercraft are not built to float!!! That aside, many hovercraft also have a problem with "starting on water" - this simply means coming to a stop (engine still running or not) and then trying to start moving forward again. You may sometimes hear the expression "getting over the hump", which is an industry term that describes the problem for Hovercraft to get back up onto the cushion of air so the Hovercraft can start moving again. If your Hovercraft cannot "get over the hump", you have once again purchased a complicated Airboat and not a true Hovercraft as you will now have to slowly chug back to shore before your vehicle will be able to fly again. In addition, many craft have a very severe tendency to spin and throw occupants when stopped quickly on water - not a safe day in the sun.
-- During demonstrations, I have seen a number of customers panick when we stop the Hov Pod on water, because of this reason. In response, I recommend fishing from the Hov Pod. The Hov Pod is designed to lift a payload of 290 kilos or 640 pounds (HP65) to 325 Kilos or 716 pounds (HP120 Turbo) for "on water" starts. The Hov Pod has been designed to quickly yet safely and smoothly stop in a controlled straight line - in fact safe, controlled stops on water are part of our demo and training manuals.
Buoyancy
Many hovercraft have poor buoyancy characteristics and can actually sink if swamped - remember that confusion about stopping on water! First engine trouble, then safety issues and finally, your Hovercraft starts to sink!
--The Hov Pod not only stops quite happily on water, but it has also been independently tested for flooded buoyancy approval. The difference in purchasing a professionally designed and manufactured craft is that it helps to overcome regulatory restrictions, where they apply. With an extremely buoyant hull, the Hov Pod is tested to take over one ton in weight before water regression is possible - at which point it still floats!
Sadly, we are at the end of our introduction to Hovercraft purchasing today! I hope it has been informative!! Keep an eye out for the next in this four part introduction to Hovercraft series. For more information visit: http://www.hovpod.com.au/

Lift engines are generally placed in front of the driver - This means that all the fumes and noise comes straight at the driver and the first wave that hits your Hovercraft may simply swamp the engine, thereby causing lift failure or the Hovercraft to 'plough in' - I hope that Hovercraft Floats! (don't be fooled, many don't).
But lets pretend that the Lift engine doesn't cause fume, or safety issues, now I'm back to my Helicopter flying days as I navigate a myriad of controls adjusting my lift engine speed and my thrust engine speed in order to drive the Hovercraft. Not only is it not simple, it's potentially expensive as I have to maintain two separate engines, fans and associated drive mechanism's.
-- The Hov Pod has only one engine for lift and thrust - since it is far easier and safer to coordinate one set of controls, more cost effective to service one engine, plus the noise footprint is lowered with only one engine. With only one engine to stow, the Hov Pod was deliberately designed without a gearbox assembly, allowing the engine to sit much lower in the craft, thereby lowering the centre of gravity, reducing the tendency to roll (I have seen other craft literally roll over in a simple low speed turn), and providing much greater ease of control. A lower engine also minimises airflow disturbance to the fan - clear airflow results in greater efficiency.
PERFORMANCE
Stopping on Land
Hovercraft should be considered as much a land-based vehicles as it is a water-based vehicle; stopping on a small rock shouldn’t cause the floor to crack, since cracks let in water. Most hovercraft have a single thin skin floor, made from glass fibre. It's important to find out just how durable your hovercraft is going to be, or you risk purchasing a complicated airboat and not a Hovercraft.
-- The Hov Pod hull is unique, manufactured from HDPE (High Density PolyEthylene). HDPE has been used to construct Formula 1 Race crash barriers and artificial joints; it is extremely strong, impact resistant and extremely buoyant. (One day, all hovercraft manufacturers will use this material). We add aluminium runners, impact sheets and wear bolts to protect the craft from the inevitable knocks that occasionally occur. There have even been Hov Pods in multiple car accidents where all cars and trailer have been written off, but the Hov Pod has been able to fly away.
Stopping on Water?
Apparently, many manufacturers tell their clients to avoid doing this. Believe it or not, some Hovercraft are not built to float!!! That aside, many hovercraft also have a problem with "starting on water" - this simply means coming to a stop (engine still running or not) and then trying to start moving forward again. You may sometimes hear the expression "getting over the hump", which is an industry term that describes the problem for Hovercraft to get back up onto the cushion of air so the Hovercraft can start moving again. If your Hovercraft cannot "get over the hump", you have once again purchased a complicated Airboat and not a true Hovercraft as you will now have to slowly chug back to shore before your vehicle will be able to fly again. In addition, many craft have a very severe tendency to spin and throw occupants when stopped quickly on water - not a safe day in the sun.
-- During demonstrations, I have seen a number of customers panick when we stop the Hov Pod on water, because of this reason. In response, I recommend fishing from the Hov Pod. The Hov Pod is designed to lift a payload of 290 kilos or 640 pounds (HP65) to 325 Kilos or 716 pounds (HP120 Turbo) for "on water" starts. The Hov Pod has been designed to quickly yet safely and smoothly stop in a controlled straight line - in fact safe, controlled stops on water are part of our demo and training manuals.
Buoyancy
Many hovercraft have poor buoyancy characteristics and can actually sink if swamped - remember that confusion about stopping on water! First engine trouble, then safety issues and finally, your Hovercraft starts to sink!
--The Hov Pod not only stops quite happily on water, but it has also been independently tested for flooded buoyancy approval. The difference in purchasing a professionally designed and manufactured craft is that it helps to overcome regulatory restrictions, where they apply. With an extremely buoyant hull, the Hov Pod is tested to take over one ton in weight before water regression is possible - at which point it still floats!

Purchasing a Hovercraft? Intro Series #1
Intro To Hovercraft Purchasing #1
If purchasing a hovercraft for the first time, there are quite a few items you need to be aware of in order to determine the right vehicle for your needs. This four (4) part series will guide you step by step through the important points to consider to ensure your safety, complete satisfaction and to that the hovercraft you choose is durable & strong.
Many issues affect Hovercraft performance, just as they do a boat, aeroplane or helicopter. Since the Hovercraft is partly all three of these vehicles, it is important that you consider a range of factors from durability, performance and safety, to the type of hovercraft skirts and hull materials used in construction. In addition, operational considerations and terms such as "ploughing-in" and "getting over the hump" should be understood and the manufacturer questioned on these items, before choosing the model and brand that will best fit you.
Introduction to Hovecraft Types
Small hovercraft can be classified as race craft, kit-build or leisure marine vessels. Depending on your needs, most buyers will fit neatly into one of these three categories, which can be delineated fairly neatly:
1. Race craft focus on speed
2. Self-build focus on low cost
3. Leisure craft focus on safety and reliability
Buyers should consider the Cost versus Performance, Safety and Reliability, when choosing the vehicle to best suit their requirements.
Race Craft
For Race craft, speed is the key objective, so weight is reduced wherever possible. For example, to reduce weight, craft have very thin GRP thereby compromising safety. Race craft are often designed for land use rather than on water. Due to the lack of durability, any impact causes expensive damage. Safety features such as the fan cage may restrict airflow and increase weight, so safety is usually compromised by speed.
-- The Hov Pod is designed for safety rather than speed.
Self-build Kits are usually favoured by folk who prefer the low cost approach and have the mechanical know-how to build their own. The backyard job often results in a lowering of quality, safety and performance. People spend considerable hours building hovercraft (200 to 400 hours) only to experience major disappointment on the first outing. That said, some people love a challenge, and are happy to spend hundreds of hours creating their own craft. But at what cost? Too much work and not enough play can make Jack a dull boy!
-- The Hov Pod has taken years of development to eliminate the pitfalls associated with Hovercraft design and manufacture.
Leisure Marine And Commercial Craft
The third type of craft appeals to people who just want to have fun. Leisure Hovercraft demand safety, reliability, and ease of use. Not all leisure craft are built the same. Some manufacturers sell new hovercraft with second-hand engines, purchased from a local salvage yard. Or produce craft that dig the nose into water and stop suddenly with dire consequences (see our 3rd blog in this series, for "Ploughing In"). Craft that do not contain enough buoyancy and sink! Craft that don’t restart on water (a paddle could be useful). Single-piece skirts that cost megabucks to repair. Hulls that crack and let in water, craft you can’t steer without throwing your weight violently into the corners.
-- The Hov Pod may not be the fastest craft in town, but we do like our customers to have fun in safety and 45 knots is enough for most. We don’t scrimp on quality either. Check out the build quality and many benefits such as stainless steel fittings to combat salt-water use, or the high spec electrical components, for trouble free operation.
Well that's all for now folks. Keep an eye out for the next in this four part introduction to Hovercraft series. For more information visit:
