Hovercraft and the Environment

For the majority of people hovercraft are new experiences. Our knowledge of them is usually gleaned from newspapers, television, magazines and the like, and consequently misconceptions are ripe.

For any vehicle to operate economically the drag, or resistance to motion, must be kept to a minimum. On water, the majority of drag arises from the motion of the vessels hull through the water; therefore we can reduce drag and consequentially propulsive power by minimising hull contact. The hovercraft achieves this by using low-pressure air to form an air cushion underneath it, thus actually lifting the hull clear of the water. In addition, by using air propulsion to generate forward movement, the hovercraft becomes amphibious, and able to traverse land, soft terrain or water.

Being amphibious, the hovercraft can use direct routes across sandbanks, marshes and flats, with no loss of speed or comfort. Channel dredging becomes unnecessary, whilst rivers and tidal estuaries present no problem for the passage of the vessel. Previously inaccessible areas may be accessed economically with little or no impact on their environment.

Damage to the shore environment, such as beaches, mudflats and vegetation is virtually nil because of the hovercraft's low pressure "footprint". For example, the average human being when standing on a beach exerts a pressure of some 3lbs per square inch underfoot, rising to 25lbs per square inch when walking. The average hovercraft by comparison, exerts a pressure of approximately 1/3lb per square inch on the surface regardless of speed. This "footprint" pressure is less than that of a seagull standing on one leg!

All Airlift Hovercraft are fully amphibious and create virtually no under water noise, just atmospheric noise levels that would be typical of a diesel truck or bus. The fact that there are no underwater protrusions or propellers eliminates the usual thrashing noise signature associated with conventional propeller driven craft, as well as negating any possible seabed erosion when operating in shallow waters. It therefore becomes obvious that fish and other marine life are in no way affected. This has been confirmed by independent scientific tests. The major noise factor with any hovercraft is the propeller noise, which in any case is largely directional in characteristic. Airlift Hovercraft's hovercraft propulsion propellers have been designed with low tip speed to minimise atmospheric noise.

All AirLift Hovercraft's hovercraft hulls are a "sealed unit'. This means that any accidental fluid discharges or leaks are fully contained within the hull structure, remaining there to be pumped out at an appropriate shore facility. There is no exhaust discharge into the water as with most conventional watercraft, thus eliminating the pollution of the marine environment by oil and fuel particles, particularly prevalent with outboard motor usage. Atmospheric pollution is also considerably less because of the inherent fuel efficiency of the modern four-stroke machinery utilised, as opposed to the very large percentage of marine propulsion units, which still utilise the two-stroke principle and discharge unburned oil into the water. In addition, because of the low friction with the surface, and subsequently low power requirements, the hovercraft is in itself a fuel-efficient mode of transport, thus lessening the pollution of the atmosphere even more. For example a fully loaded six-person hovercraft burns less fuel per hour than a typical jet ski, it does not pollute the water and does not disturb the bottom in shallow areas that many fish rely upon for food and breeding.

The wake created by the passage of a hovercraft is minimal, ensuring that riverbank erosion and damage to foreshore by the waves created is virtually nil. A study in the United Kingdom concluded that the passage of hovercraft over inter-tidal areas caused no damage to sea grasses or invertebrates. It was also noted that bird life rapidly adjusted to the presence of hovercraft. This has been confirmed on the Gold Coast in Australia, where a commercial operator passed over the same area of beach many times a day for more than three years without any affect to the 'Yabbie' population actually living in the sands directly under the flight path.

Most interesting

Sounds like a sales pitch

Are you manufacturing here?

Glad that you pitched in Wellinton. Exactly my sentiment ... a sales pitch (and it's a continualtion of another thread). No doubt 'phukethovercraft' will shoot me down, as he seems to dislike my previous commets on other topics .... :o

I asked him in another thread whether he owned a yellow mini hovercraft last seen at Chalong Bay .

He has not replied

If he does,then he is making the beasts.

Hi Guys

So what are you guys jealous or just want to complain about something/anything

The OP is not a question. The OP is an article. And the complaint is that the article might be a sales pitch. Clear enough for you.... :o

OOhhh yes sir, its clear, and i say,,, so what, dont you like if somebody try to sell something here??

if you dont like it dont read it, clear enough for you.....

Good luck to the guy at least he has some imagination and drive hope he does ok with his hovercraft, so there is some noise so what.

Some noise? Unless things have changed dramatically since I heard my last hovercraft, these will be louder than the unmuffled Longtails :D

There needs to be a serious environmental impact study as well. We don't need yet another vehicle for destruction now do we? :o

Read forum rule 7. That's my objection .... :D But I'll accept a mod decision .... :o no problem.

Hi

I dont know anything about the rules, but think there should be place for everybody here, be it selling something or not

This article about hovercraft & the environment it is not a "sales pitch". It is solely intended for the people of this island to understand the nature of these machines and the positive impact they have on the environment.

First I would like to clear up a few questions that was put to me.

1: No I do not have a yellow hovercraft.

2: These hovercraft have a four stroke engine not over 13 HP, and are quieter than a long tail boat/ jet ski/ some motorbikes/ some cars/ some boats/ and in some cases some people! ...

3: No I am not manufacturing them to sale to the local public.

4: I don’t claim to have four hovercraft, I have four hovercraft.

5: As for the need for a "serious environmental impact study". Try reading this thread first before commenting.

6: Thanks for all the positive comments on this thread.

I would just like to say that these hovercraft operate on a remote part of Phuket. I think that it will not affect anybodies lifestyle or sleep behaviour patterns whatsoever. So I think it would be good for tourism, offering a more diversity of sports & create more jobs for the locals.

As with any new business on Phuket or anywhere in the world, there will always be someone to oppose it.

Best Regards to all the readers of Thai Visa, even livinginkata.

Cheers!

So... You intend to make a business with hovercrafts on Phuket Island... ?

If so, you are using this forum as a platform to promote the business.

That's against forum rules... but hey, the mods don't seem to care, and just slam anyone who upsets the the status quo.... :o

If you don't like it, you can always do the " Funky Chicken Dance"

It works for me!

So it seems that livinginkata is a hypocrite as well as a whingger, after reading a quot by him on ( Why Build Dual Carriage Ways in Phuket?) Livinginkata quoted > No, not at waste of money. I just wizz along on the inside lane, passing all the traffic. The interesting thing it that passing on the left is completely accepted here in Thailand, no honks or finger ... don't you just luv it here, doubt whether I could ever go back to the driving discipline back home ...

IT seems that when he breaks the rules it is okay.... But if he thinks some other person breaks the rules, he is the first person to complain.

Why not just say you heard someone say it's so much a hour, I don't mind you getting a plug.
Well I have heard that if you can understand English and take note of the instructor, you can fly a hovercraft for an hour for ONLY 1,800 Baht.

You would have to sign a waiver and pay for any damages in the event of an accident caused by recklessness and careless flying.

Well it's about time this thread ends with a plug. :o

OK, so I am slightly confused

Are you or are you not renting out these units?

If so is the price 1800 per hour?

Is insurance included?

Can we rent them any day or just specific ones

Do we need to pay a security deposit?

Thanks

Alan

No security deposit is required just bring your passport with you, which we hold, just incase!

If you would like more information and to see one of these crafts in action click on the link below to see a resent interview that I had for Andaman News TV11.

Warning... Words my be muffed a little being that I have never had a camera stuck in my face and being asked questions. Even movie stars don’t get it right the first time.
