SP-38 Commercial Autopilot System



The new SI-TEX SP-38 is a feature-packed professional autopilot ideal for a wide range of powerboats and commercial vessels up to about 150’ LOA.  


SI-TEX’s Intelligent Steering Technology (IST) learns vessel characteristics over time and fine-tunes itself for optimum performance.   The SP-38 offers pre-defined operational parameter sets for full- or semi-displacement hulls, sterndrives and sailboats.  It also offers a special Work Mode designed for commercial fishing boats, towboats and workboats.    Proportional Rate Control (PRC) provides gentle and smooth steering response. 


Other professional features include Nav Mode for adaptive and precise track steering and Automatic Leeway Compensation (ALC) that adjusts for the effects of drift, tide and wind.  An optional bow-thruster interface is available for precision drift fishing and hands free station keeping.
