IRC entry
B&G H5000 CPU Hydra (1 424 € HT) yra pigiausias IRC įėjimo bilietas. Įgimtas NAC-3 suderinamumas, 10 Hz dažnis pakankamas mėgėjiškai pakrančių regatai. Apribojimai: nėra integruotų poliarų (pilotas laikosi kurso, bet nepasiūlo optimalaus kampo). Siekiant aukštesnio lygio (RORC, taktiniai skaičiavimai), rinktis Hercules.

„B&G Hercules“ (2 992 € be PVM) yra mūsų standartinė IRC klubo lygio sistema. Poliarinės kreivės importuojamos iš ORC (Offshore Racing Congress), realaus laiko layline skaičiavimas, Wave refined režimas. Jei reguliariai lenktyniaujate IRC klubo / RORC lygiu, tai tinkamas investicija — 1 500 € be PVM skirtumas, lyginant su H5000 CPU Hydra, atsipirktų per dvi sezonus grynosios naudos atžvilgiu.

Skaitmeninis Madintec MAD Brain Box (3 911 € be PVM) yra privalomas prancūziškosios lenktyninės įrangos standartas mėgėjų offshore programoms. Wave režimas yra rinkos etalonas (dažnai kopijuojamas, bet retai pralenkiamas), dažnis 50 Hz, atviras ekosistema (NKE / B&G / individualūs jutikliai). Tai dažniausias pasirinkimas daugumos mėgėjų Class40 ir IMOCA „pirminės kainos“ jachtoms. Dažniausiai derinamas su NKE Gyropilot 3 — šis derinys yra prancūziškos lenktyninės įrangos standartas.

Pixel sur Mer Exocet (9 990 € be 990 € HT bazinės centralės) yra standartinis profesionalus prancūzų kursinių architektų (Verdier, Lombard, Cammas Yacht Design) sprendimas. Modulinė sistema su individualiomis I/O sąsajomis (analoginė, serijinė), patentuotu Wave režimu, jutiklių duomenų rinkimu (korpuso deformacija, stiebo apkrova). Šio lygio įranga jau nebe „autopilotas“, o taktinės navigacijos centrinė įranga + struktūrinis monitoringas. Komercinis pasiūlymas pagal specifinį techninį užsakymą.
Budget for complete Exocet system (central unit + interfaces + custom sensors + integration): €30,000 to €80,000 ex. VAT depending on program
View Pixel ExocetThe 3 mistakes that come up when a customer chooses their racing autopilot processor without a workshop program audit.
The MAD Brain Box is designed for regular offshore racing programs (minimum 4-8 regattas/year, trained crew, polars used). On a sailboat that does 2 coastal regattas + cruising: the Hercules (€2,992 ex VAT) is more than sufficient, and the €920 ex VAT saved can fund WS720 sensors. Always match the processor to the actual racing usage frequency.
Pixel Exocet is a pro-level modular acquisition system — it requires calibrated sensors with custom calibration curves. Plugging in standard WS320 sensors without a custom analog interface means losing 80% of the system’s precision. If you want Exocet, budget for custom sensors and curves (€5,000–15,000 VAT excluded extra) — otherwise stick with MAD Brain Box or Hercules using standard sensors.
The H5000 CPU Hydra (€1,424 ex VAT) is deliberately firmware-locked (no polars, no advanced Layline). To unlock the Performance firmware, you need an unlock code (~€1,585 ex VAT). Total cost: 1,424 + 1,585 = €3,009 ex VAT, which is slightly more expensive than buying Hercules directly (€2,992 ex VAT). If you know in advance you need polars, buy Hercules directly.

NKE Marine Electronics is distributed by Skysat — 141 references in the catalog. The full online listing on the store is in progress (most NKE products are currently in draft and accessible via quote request). The Gyropilot 3 NKE is the French racing standard alongside the Madintec MAD Brain Box (often used together: Gyropilot 3 + MAD Brain Box + NKE 3D HR II sensors).

The cruising autopilot comparison tool covers Raymarine Evolution + Garmin Reactor 40 + B&G NAC-3 + B&G H5000 CPU Performance — for cruising segment + IRC club. This racing comparison tool goes further: H5000 Hydra + Hercules + MAD Brain Box + Pixel sur Mer Exocet — for offshore racing programs and tier pro. The key difference: here we discuss central navigation processors (tactical + polars + multi-source data acquisition), whereas there we discuss autopilots (pure heading control).
Wave Mode is a control algorithm that anticipates the effect of 3D swell on the boat's heading. Without Wave Mode, the autopilot reacts to heading deviation after the swell has already caused drift (1-2 second delay = 5-10° of heading lost). With properly configured Wave Mode, the autopilot anticipates wave arrival and adjusts preemptively, reducing average heading deviation by 50% in moderate to rough seas. 2026 market reference: Madintec MAD Modes (Super-pilot). Good alternative: B&G v3.5 refined (Hercules). H5000 Hydra has a basic version (more limited effect).
The 3D HR sensors (3D high resolution) measure wind in 3 axes + compensate heel + heel/heading to provide accurate true wind to ±0.3°. NKE 3D HR II: French racing standard, compatible with Madintec MAD Brain Box and NKE Gyropilot 3. B&G WS720 / WS730: vertical ultrasonic 1.1 m / 1.4 m, compatible with H5000 + Hercules. Pixel sur Mer Exocet: accepts custom calibrated sensors (proprietary analog acquisition). Sensor selection must be made before the processor — not the other way around.
Pixel Exocet is a modular system — the base central unit at 9 990 € HT includes the processing unit + WiFi/Ethernet + I/O acquisition protocol. The complete system adds: expansion modules (Digital In 16 channels ~ 1 200 € HT, connection boxes ~ 500 € HT each, control keypads ~ 320 € HT, custom cables ~ 300 € HT/m). On a full IMOCA, we’re talking about 30 000 to 80 000 € HT for an integrated Pixel system, with optional structural monitoring (Luna Technology fiber optic interrogator at 25 573 € HT for Vendée Globe programs).
The used market for MAD Brain Box exists (Madintec hardware, highly reputed for its longevity; units from 8-10 years old are still seen in Class40s). Mandatory checks before purchase: firmware version (advanced MAD modes require firmware ≥ v4.2), condition of I/O connectors (sensitive to corrosion in humid environments), is the warranty still valid (Madintec typically offers 12 months on certified used units). Our recommendation: buy through an authorized dealer (Skysat provides a certification service + 6-month warranty on racing used equipment).
Skysat has distributed B&G/Navico, Madintec, Pixel sur Mer, and NKE Marine Electronics since 2018. Comparator based on 60+ race autopilot installations from 2020–2026 — regattas (IRC cruising, offshore racing, IMOCA, Class40, TP52). 2026 indicative distributor prices (HT) for processor only (excludes 3D HR sensors, actuators, displays, custom interfaces, installation labor, and calibration).
