INSTALLING AN INTERCEPTOR TRIM AND STABILIZATION SYSTEM

( PART II)

Complete the second half of installing a Humphree interceptor system.

Installing an interceptor trim and stabilization system is not necessarily difficult, depending on how much access you have to the inner transom and wire runs. However, this Weekend Workbook does require a greater number of steps, and so we chose to cover it in two parts.

This is Part II. Our first phase (boatingmag .com/interceptors-1) in the October 2020 issue covered installation of

the Humphree X300 interceptors on a 27foot runabout with a single sterndrive. Unlike conventional trim tabs, interceptors not only trim the bow down and correct for a list, they can also add stability and dampen pitch. They can do so automatically or manually, using advanced sensors, integrated microprocessors, and ultra-fast actuators driving the interceptors’ composite blades that

deploy vertically to create hydrodynamic lift.

Here, we will complete the project with installation of the interceptor servos that drive the X300 interceptors (each 1113∕16 inches wide), the HCU501 control module, the GPS antenna, and the CP501 control panel at the helm, as well as the plug-and-play cable connections. Before you start, make sure the interceptor blades are fully retracted.
