Answering the "Single Prop vs. Dual Prop" Question
(Back to Top)

There seems to be a lot of misinformation these days when it comes to the single prop vs. dual prop question. As you might expect, some competitors who only offer single prop thrusters may use slick, sometimes even deceptive "spin" to make it seem that "single prop" is the only way to go. We guess it just makes sense since that's all they sell or maybe have the technology to produce.

WESMAR on the other hand has long been an innovator, not a copier. WESMAR invented the revolutionary counter-rotating dual prop design in the early 1990's, and since then several competitors have tried to copy it. So the question that must be asked is, "Why are they copying it if it isn't a better design?" The answer is simple, it is!

Two solid reasons why the counter-rotating dual prop design is better:

  1. When a single prop is used, a lot of the energy is lost in the "swirling" motion of the water. However, when a second prop spinning in the opposite direction is used, the swirling water is redirected back into straight-line thrust, effectively recapturing and refocusing that otherwise lost energy into real, useable thrust.
     

  2. Another advantage of the more efficient counter-rotating dual prop design is that smaller props and tunnels can be used to produce the same thrust. This allows the tunnel to be placed lower and more forward in the hull (on new installs). With better tunnel position, increased turning leverage and more precise control can be achieved.

The Bottom Line . . . Tests have proven 40% more thrust per input horsepower with WESMAR's innovative dual prop bow thruster!

bow thruster test tank WESMARWESMAR created a one-of-a-kind world-class testing lab to develop the most powerful thrusters possible. By testing each design for power, prop size, pitch, clearance and configuration, WESMAR is able to offer bow thrusters that are optimized to provide the most power possible in a given size. (click to enlarge photo)

While others talk about how much power their bow thrusters make, WESMAR is actually testing, optimizing and proving it . . . how many other companies can say that!? Single prop versions are still available from WESMAR for situations when space does not permit a dual prop, or for the economy minded boat owner, but the WESMAR counter-rotating dual prop bow thruster IS the thruster of choice for serious boat owners!
