SI-TEX SP-38 Commercial Autopilot System with Flux Gate Compass & Rotary Feedback
Description
The SI-TEX SP-38 is a feature-packed professional autopilot system engineered for a wide range of powerboats and commercial vessels up to approximately 150 feet LOA. Designed with serious captains and professional mariners in mind, it delivers precise, adaptive steering performance in demanding conditions. SI-TEX's proprietary Intelligent Steering Technology (IST) learns your vessel's characteristics over time, continuously fine-tuning itself for optimum handling and response.
With pre-defined parameter sets for full- and semi-displacement hulls, planing hulls, sterndrives, and sailboats - plus a dedicated Work Mode for commercial fishing boats, towboats, and workboats - the SP-38 is ready for virtually any vessel and operation type. Proportional Rate Control (PRC) ensures smooth, gentle steering response, while Nav Mode with Automatic Leeway Compensation (ALC) keeps you precisely on track regardless of drift, tide, or wind. This core pack includes the Flux Gate Compass and Rotary Feedback unit, but does not include a hydraulic pump.
Key Features

FAQ
Does this pack include a hydraulic pump?
No - the SP38-2 is a core pack that includes the autopilot control head, Flux Gate Compass, and Rotary Feedback unit. A compatible hydraulic steering pump must be sourced separately. If you need a complete pump-included package, please contact us to discuss the other SP-38 model configurations.
What size vessels is the SP-38 designed for?
The SI-TEX SP-38 is designed for powerboats and commercial vessels up to approximately 150 feet LOA. It supports a wide range of hull types including full-displacement, semi-displacement, planing hulls, sterndrives, and sailboats, as well as commercial workboats, fishing vessels, and towboats via its dedicated Work Mode.
Is the SP-38 compatible with my existing NMEA devices?
Yes. The SP-38 is fully compatible with onboard NMEA 2000 (N2K) network devices and supports NMEA 0183 input and output as well. It also connects via Ethernet, making it compatible with most modern marine electronics systems and chart plotters.
Can I add remote control stations?
Yes. The SP-38 supports multi-station capability with up to 4 stations, and includes a security station lock feature. A selection of remote-control units is available and can be connected via the NMEA 2000 network. An output for an optional analog rudder angle indicator is also included.
What is Intelligent Steering Technology (IST)?
IST is SI-TEX's proprietary adaptive steering algorithm. It monitors your vessel's steering behavior over time and continuously adjusts autopilot parameters for optimal performance. Rather than relying solely on manual tuning, IST learns your specific hull's response characteristics, resulting in smoother, more accurate course-keeping the more you use it.
What is Automatic Leeway Compensation (ALC)?
Automatic Leeway Compensation (ALC) is a feature in Nav Mode that automatically detects and corrects for the effects of current, tide, and wind pushing the vessel off course. Instead of requiring manual heading adjustments, ALC continuously trims the course to keep the vessel precisely on its intended track.
