Allows the USM base unit to be recovered inboard of the gunnel and stowed when not in use while maintaining calibration.
There needs to be approximately 14″ of clearance inboard of the gunnel.
A block&tackle is a good way of hinging the unit in, we sell a kit under options.
Depending on what sonar you are using a more robust solution for hinging the unit may be required like a davit and winch setup. We also have a davit and winch kit that is designed to bolt on/off a base plate. Electronic winch with wireless control and an height and reach adjustable davit.
Hinge kit option adds a larger fixed plate, 11"Wx20"L, a carrier plate for the base unit and marine grade knuckles designed and built by USM
