How does Duffy power compare to trolling motor power?
Duffy drive systems are designed to be the primary power system for the boat, developing up to 220 lbs. of static thrust. The Duffy 21 Old Bay weighs about 4,000 lbs. with 10 adults aboard and can still maintain a top speed of 6.5 knots into wind and current. The Advanced DC Motor develops tremendous torque and is equivalent to about a 10-hp gas motor.
