Overall from a Surface Drive system, you can expect greater fuel efficiency for a boat capable of achieving a cruising speed higher than 35/45 knots, zero cavitation and shallower drafts, less maintenance and exceptional astern performance, making Surface Drives the smart choice.

ARNESON SURFACE DRIVES. The tacking effect achieved by surface drives is nearly double by comparison with that obtained from the effect of a rudder blade abaft an immersed prop. Most people think this system does not like manoeuvres at low speed and on a short sea, but it is sufficient to consider that is possible to trim the drives …

The Arneson @ Twin Disc 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.

Propellers are located aft, behind the hull, increasing steering leverage and improving maneuverability at all speeds. here

Unlike conventional systems that vector prop thrust off of a rudder, the Arneson Surface Drive angles in the direction of motion, maximizing steering control and response. [links]

If you are looking for a boutique Italian performance yacht builder like Baia, we also have a 43′ Baia One for sale down in Miami. This boat is also arneson drive so it is perfect for coastal cruising. For a 43′ boat, I was really surprised how beamy this boat was and the second you see the cockpit deck it is stunningly spacious and wide. She has a great layout for entertaining with a social helm location, convertible dining / bar area, and lots of space. Down in the cabin, she has contemporary styling and solid functionality. We just reduced the price by $25k and we are now asking $399,000. more

I have a 50′ Baia Classic for sale which is a 2000HP arneson drive boat. She can hit speeds up to 50MPH which allow her to cruise from Marco Island, FL to Key West, FL in about 2.5 hours at 0.6 mpg. She has been lovingly maintained by her owner over the past eight years but he doesn’t use her as much as he used to and he would like to get her sold to another loving owner. She handles great and has a full maintenance record. She has been refit, inside and out, her soft goods are in excellent condition, she has a custom hard-top, large sunbed, extreme stereo system and is really clean. One master stateroom and one guest stateroom with two berths along with a nice dining area and galley. The wood looks great and is in excellent condition. We just reduced our price to $295,000 and I encourage all offers! Check out the video below!

So why haven’t surface-piercing drives replaced inboards and stern drives? One reason is the presence of the propellers well aft of the transom, a problem that many boat designers address with large swim platforms. Another issue is that the efficiency advantages of this drive system increase as speed increases; the drive works best on deep-V and catamaran performance boats. Slow-speed steering response is also not as good as with stern drives, inboards, and pods.  [links]

No one would really argue with the assertion that the azimuthing pod drive—commonly referred to as IPS and Zeus (the Volvo Penta and Cummins versions, respectively)—has revolutionized pleasure boating. While some argue over the precise degree of improvements in speed and fuel efficiency, virtually no one disputes the fact that this drive system represents a significant improvement in performance over conventional inboard propulsion.

[vroycehesterb]

As with any engineering breakthrough, there are those who exaggerate the magnitude of the impact. I recently read an article in which the author stated that until pods came along pretty much nothing significant had occurred in the development of marine propulsion since Archimedes invented the screw. Obviously this individual had forgotten about the Arneson Drive. 

[4u2guess]

The Arneson Surface Drive (ASD) is actually a version of what is referred to as the surfacing-piercing drive, and the name derives from its eponymous inventor Howard Arneson, an engineer and inventor who earned some 45 patents. In the early 1960s he invented a device that automatically cleaned pools. He sold the Arneson Pool Sweep to Castle and Cook in 1969 and retired from there in 1981 to pursue his real passion, high-performance boating.

[nsamiramcmillanw]

So, how much more efficient is a surfacing drive? As with pods, there’s a range of estimates depending on whom you talk to, but most experts feel 15 percent is a fair average. Note that while efficiency typically translates into more speed, it can also mean increased fuel efficiency. [links]

[sstsf]

In actuality, no. The key to the success of any surface-piercing drive is that it reduces hydrodynamic drag. Since it mounts to the transom like a stern drive and extends aftward there are no underwater appendages like struts, shafts, and rudders to create drag. In the ASD, steering is effected by a relatively small skeg that protrudes beneath the propeller housing. Because the specially designed surfacing propellers affixed to these drives are designed to work half-submerged, there is virtually no loss in “bite” or prop efficiency compared to a fully submerged prop, and propeller drag is halved. more
