1. A boat trim control system that includes a boat having a hull, sensor means for mounting on said hull to provide electrical sensor signal as a function of actual boat attitude, and means coupled to said sensor means and responsive to said sensor signal for determining attitude of said boat hull, characterized in that said sensor means comprises:

  • a housing containing a dielectric fluid, and means for mounting said housing to said boat hull,a plurality of capacitance probe means positioned within said housing in a planar parallel array of diagonally spaced pairs, each of said capacitance probe means comprising a pair of spaced electrodes immersed in said fluid that such level of fluid between said electrodes and electrical capacitance between said electrodes vary as a function of attitude of said housing and said hull, andmeans coupled to said electrodes and responsive to variation in electrical capacitance between said electrodes for determining attitude of said housing as a function of relative capacitance among said plurality of capacitance probe means.
