Massachusetts steering system manufacturer Edson International constructed its largest modern-day quadrant for sailing yacht builder Royal Huisman.
Carrying a Lloyd’s certification, it features a radius of more than 51 inches and includes a bore to fit a 17-inch-diameter sleeve on a carbon rudderpost.
Edson’s multispeed mechanical steering system for this yacht directs the helmsman’s touch of the wheel through a gearbox with an integral wheel clutch, and then to the quadrant through a chain and wire arrangement.
The gearbox allows the helmsman to adjust the steering-wheel sensitivity and power to the conditions at hand and clutch out the wheels when the autopilot is in use. Edson’s system places bearings throughout the arrangement, giving the helmsman “feel” in the wheel.
Founded in 1859, Edson has outfitted sailboats from 18 to 220 feet with steering systems. The company makes classic chain and wire, as well as CD-i geared systems, as standard production options.
