is important so let's start with a "Marty's note" about
When you look at a wind generator for your boat
there are many considerations and what you choose depends a lot
on what kind of sailing you do - and how far off shore you go
- because this determines exactly what you are looking for in
a wind generator. Here are a couple of accurate statistics for
Air compared to Ampair and Rutland for you to think about.
At the time of writing: Over the
last 10 years I have sold only around 15 individual blades for
Rutland and a single blade for an Aerogen 6 and none at all for
Ampair. All the rutland blades were sold to cruisers as spares,
the Aerogen blade was a replacement for a turbine that had an
altercation with an "object".
At the time of writing, Over the past 10 years, I have sold no
less than 950 sets of three blades for Air - that's 2850 individual
blades - that's more than 1 blade per working day. Most of these
have been sold to people who's blades had been broken or simply
failed without apparent reason.
Over the past 3 years there have been around 10 legitimate warranty
claims for Rutland and no warranty claims for Ampair.
Over that same period of time I have performed more than 150 warranties
on Air - that's one each week. That's around 12.5% of turbines
sold have come back for warranty service.
To be fair, there are some Air
out there that have been absolutely trouble free for years - but,
and it's a big but - there is a lack of consistency of quality
and I have had turbines back two or three times, especially when
they are in a windy location such as Tasmania. There are definately
less failures in the more temperate zones. Okay for the Barrier
Reef cruiser but not a lot of good for the more adventurous offshore
types - or people living in Tassie using Air for home power.
Another thing worthy of consideration
is the regulator. If something is going to go wrong with a mechanical
devise where electronics are involved, it will be the electronics
that fail almost every time. The regulator for both Ampair and
Rutland is external to the turbine. What this means is that if
you have the most vulnerable part of the set up go bung on you
- the electronics - you can fix or replace the reg but leave the
turbine up in the air and still giving power. Nice and simple.
With Air, the reg is built in, so if you have a problem with the
electronics, you have to take the whole shebang down. This is
a particularly accute pain in the rear end for people who have
mast head mounted their turbine as they need a cherry picker to
get it down, or land based people who have the turbine on a 50'
A snippet for owners of the lastest
Air Breeze wind generator with white blades, if it has been in
the air for more than 5 months, Check your blades, there is a
good chance they have been significantly degraded by the sun.
See pic further down the page Air Marine: This is a set of Air
Breeze blades from a turbine I installed on a yacht in Tasmania
last February. And this is only one example. With Rutland you
can buy a single replacement blade in the event of a problem,
whereas Air will sell as a "matched" set. I guess Rutland
have more confidence in their consistency of quality control.
Ampair blades come as a set but I've never had a request for them.
in the USA" it is claimed on the Air Breeze box. I reckon
it would be worth popping the question to the manufacturer as
to exactly what is "made" in the USA and what is made
elsewhere - and where.
For my money, being an offshore
cruiser myself, I would put reliability over style and "claimed"
output any day. The new boat I am building is named KISS, just
in case you don't know what that stands for, it is - Keep It Simple
Stupid. A good motto for the offshore cruiser and remote land
"There is hardly anything in the world that
someone cannot make a little worse and sell a little cheaper and
the people who consider price alone are this man's prey."
(John Ruskin [1819-1900]).
seems to be a little confusion between Air and Ampair that I would
like to clarify for you all.
There is a similarity with the
names that I should have noticed and addressed earlier because
Air and Ampair are very different animals.
Air are supplied by Southwest Windpower in Arizona, USA. These
turbines, in my experience, are built down to a price.
Ampair are manufactured and supplied
by Ampair Energy Ltd, a part of Boost Enery Systems Ltd, in Dorset,
England. These turbines are built up to a standard - a high standard.
There is no direct comparison to be made between Air and Ampair
turbines except for the fact that they are both wind generators
- there the similarity ends.
I am getting more and more people coming to me with broken Air
who do not want to travel that noisy and unreliable path again,
these people are changing to the quiet and reliable Ampair for
their new power supply.

Ampair 100 Wind Turbine - the
tough baby of the family.
The Ampair 100 wind Generator is a rugged, reliable,
install and forget, small turbine.
With a reputation for absolute reliability for charging battery
systems in harsh conditions. Although it only generates up to
100 watts of electrical power in practice it often outperforms
some of the so-called 400 watt machines because of its very
good low windspeed performance.
· Generates up to 100 watts
for 12, 24 or 48 volt battery systems.
· Designed to survive the severest marine environment.
· Heavy duty, all-weather generator, sealed to keep corrosion
· Permanent installation as a fit & forget unit.

Don't be deceived, this baby of the
Ampair family is tough and puts
Ampair SM- 1B and SM-3B Regulators

This little black box is the SM-1B or SM-3B regulator we usually supply with the Ampair 100. It's 155 X 105 X 55mm and nothing special - except in the case of the SM-3B - because it can handle 3 battery banks. I had a guy buy one of these recently and he said to me:
"Do you know how hard it is to find one of these"?
"No, I didn't realise that".
He said, "I have a work boat that has a start battery, a house battery and an electronics battery that I want to keep up with a small solar panel when I am not on board and this is exactly what I need".
While we normally supply these with a wind generator, there is no problem hooking up a solar array so long as the panels do not exceed 100 watt. So if this is wwhat you've been looking for, look no further.
Ampair Pacific 300 wind turbine
The Ampair Pacific 300 wind Generator system is a powerful and
reliable wind charger for larger yachts or any stand alone power
system on sea or land. The big brother to the Ampair 100, this
turbine shares the same rugged and reliable characteristics
but with the addition of the revolutionary PowerFurlTM blade
pitch control system, advanced aerodynamic blade design and
a more powerful generator.
Non intrusive operation with elegant modern styling.
Accurate aerofoil construction of each turbine blade
optimises performance, minimises noise and vibration, and improves
Rigid blade design avoids "whooping", "motorboating",
or "screaming", vibration, resonance and flutter.
Integral marine-grade sealing system protects internal
components from condensation and corrosion.
Operates with no thermal cut-outs, commutator brushes,
or complex electronics.
Revolutionary simultaneous PowerFurlTM blade pitch
control system reduces turbine speed in high winds whilst maintaining
Three phase AC output from turbine minimises voltage
drop and permits use of smaller cables; external DC rectifier
included in system.

Ampair 300 power curve
If you want to see how easy it is to install an Ampair A300 on your boat.
The Amair RG VS 50 regulator for Ampair 300 now comes in two versions.
The RG VS 50W for wind only applications. This is great for when you are adding your wind turbine to an existing solar system.
The RG VS 50WS for those of you who would benefit from have an ability to put up to 25 amps of solar input through the one regulator system. This is a great option if you are installing a new system or are adding solar that will overload your existing solar controller.
The other advantage of this regulator, even if you don't use the solar input, is that in the unikely event of a failure of the operational regulator, you have an inbuilt spare. This is something that offshore yachties would really appreciate.
Of course, if you opt for the wind only system but decide to later upgrade to having solar input also, you will be able to do this economically with the upgrade kit.
When Ampair say "Storm Proof"
they do mean it.

Ampair 600 - A powerhouse machine.
The Ampair 600 wnd generator is available in three versions. The battery charge
version for charging 24V or 48V battery banks and the grid-connected
version is available for 230V grid connection.
Ampair 600 is not your average wind turbine.
The Ampair 600-24 and 48 volt are designed for charging high
capacity DC battery banks, typically 800Ah or more. The correct
wind turbine and regulator must be purchased at the outset -
either the 24V version or the 48V version - as it is not economically possible
to change the voltage at a later date. The wind turbine must
be installed in conjunction with the Ampair 600 regulator which
includes the regulator itself plus the dump load, fuses, rectifier,
stop switch and heatsinks.
Ampair 600 - 230 for grid connection.
The Ampair 600-230 is designed for connecting to 230V 50Hz grid
systems operated by public utilities. It is ordinarily connected
on the client's side of the electrical utility supply meter
and is ideally connected into the consumer unit (fuse board).
Electricity generated by the wind turbine is then used in preference
to electricity supplied the public utility.
The Ampair 600-230 must be installed in conjunction with the
Ampair interconnect set which includes a G83 sine wave inverter;
stop switch; overloads; power conditioning; and isolation.

Okay, let's get "Serious". - Ask yourself these questions.
· Are you a "serious" cruiser?
· Do you have a "serious" problem keeping the
batteries up at sea?
· Do you need some "serious" power?
· Are you "seriously" tired of running the
engine 3 hours each day?
This baby can probably do it for you.
A tow generator is the most effective way to charge your batteries
If you average 5 knots, as most cruisers do, you can accumulate
75 amps @ 12 volt over each 24 hour period, probably enough
to run an efficient fridge and an autopilot - two big on board
Generates approx 1 amp per knot boat speed (12v) at average
Rope transmits power of spinning turbine to on-board generator.
Gimbal mounting of generator gives fool-proof operation &
Simple installation from stern rail - no permanent hardware.
Thousands in use worldwide. Hundreds of circumnavigations made.
Highly suitable for use on long distance blue water cruising
Wind turbine conversion available for use at anchor.
The Aquair pedigree
Proven over thousands of miles of ocean cruising. Reliability
is achieved by using a towed turbine on a 30 metre line directly
coupled to the alternator shaft. Totally sealed alternator. Stainless
steel gambol ring provides a simple and automatic alignment method.
Built to professional standards for long term endurance and backed
by full manufacturers warranty. The Aquair 100 is constructed
of marine grade materials for minimal maintenance. Only a spare
turbine is recommended to cater for accidental loss. Electrical
contact is direct to the battery using a simple on/off control
With the use of the optional wind conversion kit, this generator
can be used as a wind turbine when on anchor.
Able to produce a continuous output up to 7 Amps at 12 volts.
Permanent magnet alternator, has no commutator brushes, windings
cannot overheat so requires no thermal cutouts.

Aquair 100 Power Curve
Made by Ampair
How you supply your power really depends on what kind of sailing you do. If you are a serious sailor but a coastal cruiser, who rarely spends more than a few hours at sea and tends to day hop along the coast, perhaps a tow generator is not for you. This is when a good, powerful, wind generator comes into its own, something like the Ampair 300. The A300 will give you power at sea, in port, on anchor - no fuss, no bother.
However, if you are a serious cruiser who sails offshore, 4,5,6 days at a stretch, you will probably be trade wind sailing with minimal wind over the boat, but your boat speed will still be there and an Aquair
will use that powerful and viscous medium we love so much - water - to give you a consistent power supply.
As an offshore sailor myself, I will be fitting an Aquair water generator to my new boat along with an A300 and 2 X 60 watt soalr panels. I reckon that will keep me pretty well covered. The Aquair will be the key at sea, the A300 will be the key on anchor and the solar panels will be there to "sustain" on those quiet days on anchor.
Ampair UW 100
100 micro hydro generator
A submerged generator for fast flow zero head streams.
The UW100 is a submerged generator designed for charging 12/24-volt
battery systems from fast flowing zero head streams. Strictly
speaking it is a picohydro generator ideally suited to:
Water Supply Monitoring.
This unit stands out from the crowd in submerged generators.
Designed for us in fast flowing fresh water rivers, mountain
streams & water pipe systems.
Can be used with success on a yacht at sea but is not designed
to do so and may have a limited life span due to galvanic activity.
The UW100 offers the opportunity to generate up to 2.4kWh per
day from any 400mm deep (15") fast flowing stream. When the
stream flows at 8-knots (7mph; 15kph) the UW100 will produce 8
amps continuously, and when the stream flows at 6-knots (5mph;
10kph) it will still produce 1.5kWh per day. And remember that
a stream can be diverted into a narrow culvert to increase flow
Starts charging at flows below 1m/sec (2 knots) - generates up
to 8amps at 12v.
Proven to depth of 10m.
All water joints (mechanical & electrical) are double sealed.
The oil filled housing has a pressure expansion chamber to allow
operation at intermediary depths & in all temperatures.
UW 100 technical description
The UW 100 is a submerged water powered generator for 12/24 volt
battery charging. It is a self-contained unit, (on-shaft propeller,
streamlined housing, sealed alternator with pressure relief chamber),
operating to depths of 10m below the water surface. The UW 100
features low waterspread cut-in (1½ knots) and a high charge
rate (8 Amps) without sacrificing space for weight. The body is
filled with hydraulic fluid to eliminate corrosion and to equalise
temperature-induced pressure changes.
The forward facing 3 bladed propeller drives a permanent magnet
alternator producing up to 8 Amps output current for a 12 volt
system. The shaft rotates in double seals for optimum protection,
backed by twin O-ring static seals at the rear of the casing.
The cable exit is similarly double sealed by an internal moulding
and external gland. The alternator body is filled with hydraulic
fluid to eliminate corrosion and to equalise pressure changes
caused by ambient temperature.
UW100 electrical information
Four metres of 4-core cable connects to two external rectifiers
fixed on a heatsink which should be mounted in a suitable dry
location near the battery. The output control switch and fuse
are wired in the DC battery line. Any connector in the AC cable
needs 4 individual contacts.
There a variety of different propellors available in production
with the following three menu choices:
Shrouded or unshrouded
Shrouded propellors should be slected whenever the water may contain
rope or fishing line fragments, fine weed, or plastic debris.
Clockwise or anti-clockwise rotation
Normal propellors rotate clockwise. The anti-clockwise version
is to balance towed buoys with twin underslung units.
Standard pitch or coarse pitch
Standard propellors are ideal for low speed start-up (1.8-knots)
and thereafter produce approximately 1-amp per knot. Above 8-knots
(4 metres/second) the coarse pitch (low RPM) propellor should
be selected. This also reduces propellor drag at low speeds which
is useful for racing yachts.

The Rutland 913 is designed specifically for marine use on coastal
and ocean going yachts, so they say but, what I canot figure out, why is the tail steel and will rust. But rutland will be at home on your home or
campervan. The Rutland 913 has been a common sight in marinas
for many years and thousands are in use worldwide but are a pretty agricultural machine that will not cop sutained high winds. (See: The Ampair Difference). A quiet turbine that may give fair service in temperate conditions. In my opinion, not a wind generator for the serious cruiser.An economy wind generator that will spin in the lightest of breezes! Whether it is producing any power or not is another thing!

Breeze and Air X Marine Wind Generator.
At the time of writing, Air Marine wind generator had been around
for 13 years or so. Unfortunately, despite all their previous bad
experiences and many hassles with the Air range, the lastest turbines
are a long way from being hassle free.
If you are the type of yachtie who sits in a marina and does the
odd coastal passage, always in striking distance of a service point,
and want a turbine that looks "pretty" on your boat, then
Air Breeze may be for you. Certainly the best looking wind generator
currrently on the market. However, if you are a more serious cruiser
who is looking for a wind generator you can put up and forget about
for a few years, then, in our opinion, you will be better off to
forego the "good looks" aspect of your wind turbine and
go for something like an Ampair Pacific 300 and sleep at night when
the wind blows.
Too many problems with Air Marine so we no longer sell or recommend them.

more to think about!
This completely burnt
out Air Breeze was a result of some heavy winds, nothing real serious,
50 knots in the gusts. The coating and insulators have completely
burnt off the stator so you can rattle the windings like a tamborine.
And this is not an isolated case.
See these pics.
The rusty 913 tail was on a turbine less than 6 months old. The owner had the original tail rust and this one is the replacement he fitted.
The trubine on the right was set up in South Australia, after 3 months a big blow came through and destroyed this turbine - destroyed it. The owner called me and said, "Marty, what can I put up here that will go the distance"?
I said "Pay the money and out up an Ampair 300". He did and I haven't heard from him again.
Especially designed for the marine environment!
