Super-Chargers, Turbo-Chargers, NOS, Compressors…fast cars have their fair share of boosting speeds to keep speedoholics pressing down on the right pedal…

When it comes to boats…the Arneson Surface Drives are the catalysts that converts your boat into a SPEED-DEMON…and at the same time they are efficient and maintenance-free…

NEED FOR SPEED

Conventional propulsion systems (usually assisted by shaft transmission and immersed propellors) allow a good performance for top speeds of 30 knots…maximum 40 knots!

In order to reach speeds in the range of 40, 50, 60 knots at regular intervals and with ease…the Arneson Surface Drives have proven to be the best technology in recent years.

ARNESON AND ITS MODELS

The articulated system, developed by Howard Arneson and known as the Arneson Surface Drive (ASD), allows the driver to change the amount of prop in or out required as per draft conditions.

The Arneson Surface Drives are among the most efficient marine propulsion systems in the world. Their surface-piercing propeller design reduces underwater drag by 50% compared to conventional submerged propeller drive systems. The only surfaces to contact the water are propeller blades and a protective skeg. This results in higher overall speed, quicker acceleration, and a better payload to power ratio… AND… 50% less drag significantly improves fuel economy while lowering operating costs.

For work, pleasure, gas, diesel, or turbine power systems capable of torque outputs exceeding 30,000 ft. pounds, the Arneson Surface Drives come in ten model sizes and various configurations for each model. Available in, Aluminum or bronze castings, straight or drop-center models, 12 or 24 volt compatible systems, plus the new Arneson Dual-Fin surface drives available in the ASD8 and ASD10 models.

BENEFITS

Some of the benefits commonly associated with Arneson Surface Drives are :-

1) More Speed – 15% to 30% speed increase over conventional systems

2) More Efficient – 15% to 30% increase in fuel efficiency

3) Easy to maintain – Corrosion resistant

4) Flexibility – Propellors can be adjusted when underway.

5) Comfortable – Less Vibration than Inboard or I/O applications

6) Platform-Independent – Adaptable to a wide range of engine applications, whether gas, diesel, or turbine; and of various outputs.

INDUSTRY SPEAK

Pershing – one of the most famous makes of Italian luxury yachts, has the Arneson Surface Drive on almost all of its range – from the Pershing 50 to the Pershing 90!

Alessandro Diomedi says “Arneson is simply a more efficient system, that means going faster with the same gas, therefore arriving to destination earlier, therefore burning less fuel.

Or going at the same speed at but with less RPM as compared with a conventional shaft system.

In all, more efficient means saving on gas too, and it’s more and more important nowadays.

On top of that there are great advantages in terms of handling of the craft, maintenance and usage in shallow draft, that come with the Arneson system.

Which is why we install only Arneson on our range and not as an option but as a standard.”

The fact that Pershing use various models of the Arneson Surface Drive over their range should put a lot of misconceptions to rest.

We will be see more and more extensive use of this technology as the Indian market matures for the kind of boats that use the Arneson Surface Drive.
