Cabling: the invisible art of onboard connection

Cabling is the backbone of any onboard electronic system. A well-designed and properly installed cable network is essential to ensuring the reliability and performance of your navigation, communication, and entertainment equipment. At Skysat, drawing on our experience in offshore racing, we offer a carefully curated selection of cables, connectors, and accessories for a durable and high-performance installation. Here you'll find proven solutions to meet all your needs, from simply connecting an instrument to setting up a complex NMEA 2000 network.

Choosing the right cable: the importance of specifications

Selecting the right cable is crucial. Marine environments (humidity, vibration, corrosion) demand specific materials and construction. The cable type (power, data, video) also influences the choice, as do the length and cross-section required to prevent voltage drop and ensure optimal signal transmission. Compliance with standards (RoHS, CE) guarantees quality and safety.

• Marine power cables: Designed to resist corrosion and vibration, with reinforced insulation for added safety. Check the maximum amperage rating and the appropriate cable cross-section based on the connected load.
• NMEA 2000 cables: Essential for communication between instruments and compatible displays. Choose NMEA 2000 certified cables for guaranteed interoperability.
• Ethernet cables: For connecting radars, IP cameras, and other devices requiring high data rates. Shielded cables (FTP or STP) are recommended to minimize interference.
• Coaxial cables: For VHF, AIS and GPS antennas. The impedance (50 ohms) must match that of the antenna and the transceiver to avoid signal loss.

Connectors and accessories: a reliable and durable connection

The quality of the connectors is just as important as that of the cables. Corroded or poorly crimped connectors can lead to failures and malfunctions. Choose waterproof and corrosion-resistant connectors suitable for marine environments. Appropriate tools (crimping pliers, wire strippers) are essential for making clean and durable connections.

• Waterproof connectors: Provide protection against moisture and water splashes. Deutsch DT connectors are particularly valued for their robustness and watertightness.
• Terminal blocks and connection strips: Facilitate power distribution and cable connections. Choose models with vibration protection.
• Heat shrink tubing: Protects and insulates electrical connections. Choose tubing with internal adhesive for optimal sealing.
• Cable ties and fasteners: To secure cables and prevent them from dragging or tangling. Use UV-resistant ties for increased durability.

the importance of structured cabling

Well-organized wiring makes maintenance and troubleshooting easier. Use labels to identify each cable and connection. Group cables by function and use cable trays to protect them from chafing and damage. A clear and accurate wiring diagram is essential for documenting the installation.

• Cable trays: Protect cables from friction and mechanical damage.
• Cable markers: Facilitate the identification of cables and connections during maintenance.
• Electrical diagrams: They document the installation and facilitate troubleshooting. A clear and precise diagram is essential.
• Junction boxes: Allow connections to be grouped together and protected from the elements.

💡 Skysat's advice

Before beginning any wiring work, disconnect the power supply. Then test each connection with a multimeter to check for continuity and the absence of short circuits. Paying close attention to the quality of the crimping and the sealing of the connectors will ensure the longevity of your installation.
