Some marine propulsion systems use two propellers mounted at some distance from one another along the stern edge of a watercraft.  Other dual prop systems take a different approach entirely, placing two propellers onto a single engine.  This is the case with Volvo duo props.

First introduced in the early 1980s, Volvo duo propellers were a true leap ahead in marine propeller technology.  Volvo propellers using duo prop technology feature twinned propellers that rotate in opposition to one another in order to cancel out any lateral forces that may be acting on the watercraft.  This essentially means that all the forces left tend to drive the boat forward instead of allowing it to veer to one side or the other.

Advantages of Volvo Duo Propellers

Because lateral forces are no longer an issue, these duo props provide boating enthusiasts with a faster rate of acceleration even as they optimize fuel use for better efficiencies.  In addition to acceleration that may be more rapid by as much as a full third of the previous rate, Volvo duo props also increase the top speed that is possible for a watercraft.  In some cases, this improvement has measured as much as 5%.

Improvements in fuel consumption are equally impressive.  When only a partial load is in play, fuel efficiency may be reduced by as much as 10%.  At the same time, boaters will experience lowered levels of both noise and vibration, which helps to create a more pleasant atmosphere for everyone aboard.
