Boom Angle Indicator
Harken’s boom angle indicator comes as a simple-to-install retrofit kit for custom and megayachts to help crew keep the boom angle correct while furling. It is far less costly and much easier to service than other angle indicators, which are integrated inside the hydraulic cylinder.
As the boom moves up and down, its angle changes relative to the mast. This information is sent to the Program Logic Controller (PLC) where the crew views the data, adjusting the boom for uniform distribution of the sail stack. Analog or digital output from the PLC connects to the yacht’s computer system for remote display.
Kits come with a PLC, two IP 69 inclinometers, and cable. Power-in and signal-output cables required.
Use on custom and megayachts 18 m (60 ft) and up.
The system is easily calibrated onboard by a professional rigger.
