Benmar has been an award winning world leader in marine autopilots for more
than forty years. During that time, Benmar engineers have gained valuable
insight into the needs and expectations of boaters in regard to autopilot
performance and longevity.
Unique Design -  No
Rudder Feedback Device
Benmar autopilots are unique by
design. No other autopilot uses Benmar’s proprietary
proportional rate system, the
smooth, precise control method that steers your boat like
you do, constantly making the gradual and intuitive rudder
corrections necessary to keep on course. You can feel the difference, especially
when encountering heavy following seas. Since Benmar’s
proportional rate system does not require rudder position feedback, automatic
trim and counter rudder are inherent to all Benmar autopilots. As sea
conditions, boat speed and side loads change, the Benmar autopilots
automatically compensate for those factors. The result is a smoother,
straighter course, time after time.
Proportional Rate
Benmar’s proportional rate
autopilots are easy to install and highly adaptable to a variety of applications
including stern drive and outboard powered boats because there is no need for
clumsy and fragile rudder feedback devices. On-course accuracy is additionally
enhanced due to Benmar’s specially designed magnetic card compass that is uniquely engineered for supervising autopilot operation.
Benmar is the world’s most experienced manufacturer of marine autopilots.
Each Benmar autopilot is designed and manufactured at Benmar’s facility in
Idyllwild, California.
Benmar . . . dependable, reliable, accurate and responsive . . . the best
autopilot for your boat.
