Pendulum Wiper

A pendulum wiper is a marine windscreen wiper with a single pivoting arm that sweeps the blade through an arc across the glass. The blade changes angle as it moves, clearing a fan-shaped area of a wheelhouse, bridge, or helm window.

For boaters, a reliable pendulum wiper helps maintain visibility in Rain, sea spray, and salt build-up, especially when manoeuvring in harbours, crossing bars, or keeping watch offshore. The sweep area depends on the Wiper Arm length, blade size, and the torque and speed of the Wiper Motor.

Pendulum systems are simpler than a Pantograph Wiper, which keeps the blade more upright and often clears a squarer area. Before heavy weather, check blades, spindle seals, wiring, and washer fluid; PredictWind rain, wind, and wave forecasts help anticipate when reduced screen visibility may affect safe navigation.
