La electrónica del velero: esquemas e ideas para una instalación eficiente.

Overview of Sailboat Electronics Installation

Introduction to Sailboat Electronics

• The discussion focuses on creating a simple schematic for the electronic installation of a sailboat, emphasizing the integration of modern tablets with Wi-Fi receivers as essential accessories.

• A protective case is recommended for tablets to withstand harsh marine conditions.

Structure and Comparison to Neurons

• The speaker compares the electronic installation of a sailboat to a neuron, illustrating how sensors and antennas are positioned at the ends while processors and displays form a network in between.

• This analogy helps simplify understanding the basic structure of an electronic network on a boat.

Terminal Placement Considerations

• Key considerations include where to place terminals and what types are necessary, focusing on two main areas: the cabin and the helm (timón).

• The cabin serves as a stable area for calculations and communications, often referred to as "la derrota" in professional settings.

• The helm is crucial for real-time navigation; it requires instruments that can be easily viewed despite external conditions like darkness or weather.

Essential Components of Sailboat Electronics

Primary Equipment

• The radio is identified as the most critical component for boats navigating near shorelines; specifically, VHF radios are highlighted.

• A secondary terminal may be installed at the helm for communication purposes, ensuring safety through effective listening capabilities.

Antenna Placement

• It’s important that radio antennas are placed at elevated positions (e.g., top of the mast), which enhances signal reception.

Integration with GPS Systems

GPS Configuration

• An ideal setup includes a VHF radio connected to an internal GPS unit with Wi-Fi capabilities, allowing access to network data from various devices.

Additional Sensors Required

• For comprehensive navigation equipment, additional sensors such as depth sounders and speed transducers must be installed. These can either function independently or together within one unit.

Network Connectivity

Establishing Connections

• A network cable connects all instruments back to a central display where vital data can be monitored by the helmsman.

Navigation Technology Overview

Essential Screens for Sailing Navigation

• A minimum of one screen is necessary, but two are recommended: one for real-time wind data (apparent and true wind angles and speeds) to enhance sailing navigation.

• The second screen, referred to as "multi," displays various parameters related to wind speed at the surface and depth, which are frequently presented in this format.

Integration with Tablets

• The integration of a tablet with the navigation system is highlighted; both devices can connect via Wi-Fi, allowing for remote control and monitoring from anywhere on the boat.

• A 7-inch tablet priced around 700 euros serves as a modern tool that enhances navigation capabilities by providing graphical presentations and operational controls.

Safety Features in Navigation

• For safety in maritime traffic areas, installing an AIS Class B device is advisable. This device emits signals through an antenna positioned as high as possible.

• The AIS Class B includes a GPS antenna that can be placed under deck, enhancing positioning accuracy while maintaining connectivity with tablets.

Data Presentation and Compatibility

• Multiple GPS antennas (three total) provide diverse positioning data during navigation, which can be displayed on tablet screens using compatible applications like avionics.

• Avionics software allows linking various devices (e.g., Bianchi or McMurdo), facilitating real-time data reception from instruments displayed on navigational screens.

Advanced Navigation Tools

• Real-time information from the AIS Class B enables identification of nearby vessels by name and navigational parameters directly on the tablet interface.

• Incorporating an autopilot system significantly enhances comfort during long routes by reducing reliance on crew members for steering tasks.

Autopilot System Components

• A good autopilot system may cost between 5,000 to 6,000 euros; it’s essential for efficient long-distance sailing despite its high price tag.

• Key components include a processor acting as the system's brain, which connects to various elements such as servomotors for steering control and electronic compasses for orientation tracking.

Feedback Mechanisms in Autopilot Systems

• The feedback mechanism involves sensors that track the position of the rudder blade; without this data, the autopilot cannot function effectively.

Control Unit Placement and Design Considerations

Importance of Control Unit Location

• The control unit must be logically positioned next to the helmsman, as it is common for the pilot to alternate between manual steering and using autopilot features.

• The design ensures that the helmsman's hand can reach both the steering wheel and the control screen simultaneously, which is crucial for effective operation.
