{"product_id":"navico-nac-d-ordinateur-pilote-automatique-nmea2000","title":"NAC-D Autopilot Computer","description":"\u003cp\u003e\n    Designed for modern electronic steering systems, the Navico NAC-D autopilot computer (part number 000-15621-001) is a dedicated \"steer-by-wire\" solution. It provides direct integration with electronic engine control systems (EVC) from brands such as Volvo IPS\/EVC, Yamaha Helm Master\/single engine, SeaStar Solutions Optimus, and Yanmar VC10\/JC10. Unlike traditional autopilot computers like the NAC-2 or NAC-3, which require a hydraulic pump and rudder angle sensor, the NAC-D significantly simplifies installation by connecting directly via NMEA 2000 without the need for additional hydraulic components or in-harbor rudder calibration.\n\u003c\/p\u003e\n\n\u003ch3\u003eAdvanced integration and connectivity\u003c\/h3\u003e\n\u003cp\u003e\n    The NAC-D stands out with its NMEA 2000 connectivity, featuring two Micro-C ports and 2 LEN for seamless integration into the vessel’s electronic ecosystem. Its design excludes NMEA 0183, Bluetooth, or Wi-Fi support, focusing on reliable CAN-bus communication for Optimus steering systems. The device is powered via the CAN network (9–16V) with a typical consumption of 40mA, making it energy-efficient. Control can be managed via dedicated controllers such as the AP 44 or AP 48, or integrated into compatible Simrad multifunction displays.\n\u003c\/p\u003e\n\n\u003ch3\u003ePerformance and steering features\u003c\/h3\u003e\n\u003cp\u003e\n    This computer integrates Navico’s Continuum Steering technology, ensuring precise and reliable course-keeping. The SteadySteer™ function optimizes rudder performance across different points of sail by automatically switching between two speed profiles. The NAC-D offers an extensive range of advanced turning patterns, including U-turn, spiral turn, zigzag, C-turn, box turn, S-turn, and depth tracking (Depth Counter Tracking). With an IP44 ingress protection rating, a weight of 0.1 kg, and compact dimensions (86.5 x 20.0 x 11.5 mm), it installs discreetly inline with the cable, requiring a 0.5-meter safety distance from the compass.\n\u003c\/p\u003e","brand":"Navico","offers":[{"title":"Default Title","offer_id":53723891728724,"sku":"000-15621-001","price":1008.76,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_f53f175c-101e-4be3-be9a-630a7f1ba223.jpg?v=1772639546","url":"https:\/\/skysat.fr\/en\/products\/navico-nac-d-autopilot-computer-nmea2000-8","provider":"Skysat","version":"1.0","type":"link"}
