IRC entry
B&G H5000 CPU Hydra (1 424 € HT) er ódýrasti valkostur fyrir IRC-keppnir. Hefur innbyggt NAC-3, 10 Hz tíðni sem dugir fyrir strandakappakstur á hálfgerðum áhugamönnum. Takmarkanir: engar innbyggðar vindstefnur (stýrimátturinn heldur stefnunni en gefur ekki uppskeru bestu áttanna). Fyrir efra stig (RORC, taktískar útreikningar), skipta yfir í Hercules.
Budget H5000 CPU + WS320 sensors + NAC-3 + T1 actuator installed: ~ 7 500 € HT

B&G Hercules (2 992 € HT) er okkar staðla viðmiðun fyrir franska IRC klúbba. Pólur innfluttar frá ORC (Offshore Racing Congress), rauntíma layline reikningar, Wave refined módus. Ef þú siglar reglulega í IRC á klúbbastigi / RORC, er þetta rétt fjárfesting — 1 500 € HT munurinn gagnvart H5000 CPU Hydra endurgildist á tveimur tímabilum í hreinni afköstum.

Madintec MAD Brain Box (3 911 € án viðskipti) er franskur viðmiðunarval í kappakstursforritum fyrir áhugamannastig og upp fyrir. Wave-staðall (oft eftirmyndaður, sjaldan jafn góður) með 50 Hz tíðni og opið vistkerfi (NKE / B&G / sérsniðnir nemar). Val hjarta flestra Class40 áhugamanna og IMOCA "fyrsta verðlauna" bátanna. Oft notað með NKE Gyropilot 3 — staðlað kappaksturspar í Frakklandi.

Stjórnborðið Pixel sur Mer Exocet (9 990 € HT fyrir grunnstjórnborðið) er franskur atvinnustandard hjá skipshönnuðum í kappsiglingum (Verdier, Lombard, Cammas Yacht Design). Breytanlegt kerfi með sérsniðnum I/O tengingum (analóg, raðtenging), eigin Wave-stillingu, og skynjun á byggingarskynjun (skrokkurbreyting, seglspenna). Á þessu stigi fer maður fram úr einfaldri "stjórnborðsstýringu" og inn í taktískt siglingastjórnborð + byggingargagnvirki. Tilboð gefið út samkvæmt sérstökum verklýsingu.
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 a racing 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 modular pro-level acquisition system — it requires calibrated sensors with custom calibration curves. Plugging in off-the-shelf WS320 sensors without a custom analog interface means losing 80 % of the system’s precision. If you want Exocet, budget for custom sensors + calibration curves (€5,000–15,000 VAT excluded extra) — otherwise, stick with MAD Brain Box or Hercules using off-the-shelf sensors.
The H5000 CPU Hydra (1,424 € VAT excluded) is intentionally firmware-limited (no polar diagrams, no advanced Layline features). To unlock the Performance firmware, you need an unlock code (~1,585 € VAT excluded). Total cost: 1,424 + 1,585 = 3,009 € VAT excluded, which is slightly more expensive than buying Hercules directly (2,992 € VAT excluded). If you know in advance that you need polar diagrams, buy Hercules directly.

NKE Marine Electronics is distributed by Skysat — 141 references in the catalog. Full online listing on the store is in progress (most NKE products are currently in draft, accessible via quote). 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 — 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 third-party pro setups. The key difference: here we discuss central navigation processors (tactical + polars + multi-source data acquisition), whereas there we discuss autopilots (heading-only control).
Wave Mode is a control algorithm that anticipates the effect of 3D waves on the boat’s heading. Without Wave Mode, the autopilot reacts to heading deviation after the wave has already pushed the boat off course (1–2 second delay = 5–10° of heading lost). With Wave Mode properly tuned, the autopilot anticipates wave arrival and adjusts preemptively, reducing average heading deviation by 50% in rough seas. 2026 market reference: Madintec MAD Modes (Super-pilot). Good alternative: B&G v3.5 refined (Hercules). H5000 Hydra has a basic version (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 sensors 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 unit at 9,990 € HT includes the central processing unit + WiFi/Ethernet + I/O acquisition protocol. The complete system adds: expansion modules (16-channel Digital In ~ 1,200 € HT, connection boxes ~ 500 € HT each, control keypads ~ 320 € HT, custom cables ~ 300 € HT/m). On a full IMOCA, the Pixel system alone can easily reach 30,000 to 80,000 € HT, with optional structural monitoring (Luna Technology fiber optic interrogator at 25,573 € HT for Vendée Globe programs).
The used MAD Brain Box market exists (Madintec hardware highly reputed for its longevity; units from 8-10 years old are still in service in Class40). Mandatory checks before purchasing used equipment: 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: go through an authorized dealer (Skysat offers a certification service + 6-month warranty on used racing equipment).
