Yacht-engineering is a job that requires a lot of skills. And one of the major tasks yacht marine engineers have to do on board is to deal with the yachts electrical system and electronic systems. This includes designing and fabricating this electrical system, documenting, testing and troubleshooting this system before installing it, observing changes in the production process and providing input on how to change the electrical system accordingly.
The ability to do all this is key in order to provide a safe yacht with no fire hazards or electric shocks for the people on board. In addition, these different levels of expertise will help yacht marine engineers not only avoid mistakes and problems onboard but also come up with innovative ideas that may be implemented in the production process of yachts, making them more safe and efficient.
Most marine engineers around the world have at least a basic knowledge in yacht-engineering. However, there are also some specific techniques that may be required only for certain jobs or areas of expertise. For example, on board construction relies heavily on 3D modeling software such as Catia and Solidworks in order to help the engineers build a wireframe of the yacht’s electrical system. This can either be done from scratch or as a modification of an existing model in order to match some new specifications. In addition, marine engineers must have good working knowledge on basic electronics since they will make connections between sensors, computers and actuators.
Some of the top yacht-engineering techniques every marine engineer should master include:
– Designing and fabricating the yachts electrical system. This includes choosing between different wire types (such as copper, aluminum or fiberglass), cable types (e.g. twisted pair) and insulation materials (e.g. polyethylene). It also includes choosing the right circuit breakers, wires and fuses.
Small boats usually have a simple electrical system with only one DC wiring. This type of electric power supply uses one positive wire (called “Hot”) and one negative wire (called “GND”). The Hot wire is connected to all the devices in order to provide them with electricity. The GND wire is connected to the ground and to every device that has metal parts in order to prevent electric shocks. In addition, marine engineers must be careful when using DC circuit breakers since DC current flowing through fuses will heat up the wires until they burn down or melt.
Upgrading from a simple single-wire system may be a good idea in order to provide more power and to also be able to monitor some devices (such as the wiring and other sensors). Using multiple wires enables the use of AC current, which is more efficient than DC current. This means that most electronic components don’t have any problem functioning with 50 or 60Hz.
Traditional AC systems use three wires: a positive one (Hot) and two negative ones (GND). This type of electrical system is called “Three phase”. It can be used to provide more power for devices, such as the engines or air-conditioning units. Another benefit of a Three phase system is that it allows monitoring and managing each wire separately, which is not possible with a single-wire system.
This is what the layout of a three-phase AC current looks like:
The use of this type of wiring enables monitoring not only by voltage but also by amperage, which helps detect electrical problems and understand how much power each device draw from the power supply (which is important for smaller yachts).
But what happens if a wire fails or there is an overload? It would be impossible to use breakers with this type of system, since the problem can show up only at certain times (e.g. some phases may stop working but not others). This is why instead of using them, marine engineers must choose circuit breaker panels that disable individual wires. This is not as efficient for the power supply, but it will save your boat from fire just in case one of the panels malfunctions.
Using large boats as an example, a good combination of wire types and insulation material may mean more safety and less maintenance over time:
– Documenting, testing and troubleshooting the electrical system before, during and after installation for adherence to safety standards. This includes:
– Verifying the compliance of an electrical system with a yacht’s class rules by comparing it with the corresponding certificate of compliance (CoC). – Measuring each wire and cable as well as each circuit breaker (in order to make sure they are not overloaded) – Verifying that DC system fuses or breakers are in accordance with the standards. – Checking that bus bars and all wiring installations are insulated by observing insulation continuity (e.g. resistance must be within limits)
– Measuring the impedance of each wire and cable using an electric tester, which will help determine if there is water penetration through cable sheaths. – Testing and troubleshooting each circuit breaker panel by measuring its impedance in order to verify that it is not defective or overloaded.
– Monitoring the power distribution system over time using a digital voltmeter, which will help detect spots with low voltage (caused by resistance) or high voltage (caused by electrical faults).
– Sizing the electrical system in order to estimate how much power the yacht requires, which will help determine if all breakers are of adequate size. This means that you must know:
– The total energy and power consumption of each device (which can be found on its technical sheets or by multiplying volts times amperages) – How long each device is used during a day and how many days a year (this is needed to estimate the total power consumption of each device)
– Calculating if the electrical system has enough capacity by dividing the power required by the number of hours it will be used
– Checking if there are any gaps in devices wiring which could cause an overheated wire or open switch.
– Checking if the wires and cables are properly installed (e.g. verifying that a wire is soldered correctly, at the correct place and orientation)
They use even more ways to monitor systems on large yachts nowadays, but then again you can always hire an engineer to check your boat or maybe read some books about yacht electrical engineering.
All of these techniques and procedures are vital for your yacht’s health, not only because they ensure safety and compliance with standards, but also because they help you save money by preventing future damage to your boat (since repairs will be less expensive if an electrical system is well documented).
Although the first two techniques mentioned above can be learned in a few days, it may take years to master them. One of the most important skills in yacht engineering is the ability to troubleshoot electrical problems (e.g. when the lights don’t work or a breaker suddenly trips). In order to do so, you must be prepared:
– Make sure that there are no signs of water penetration (e.g. condensation signs, rust on the fixtures). – Make sure that all connectors are tight and in place. – Make sure that there is no loose wiring or damaged parts (e.g. burnt wires, broken cabinets)
– Test each circuit breaker by turning them on one by one to see if they trip properly or if any lights dim. To troubleshoot an electrical problem you must be able to:
– Locate the faulty part (e.g. burnt wire, broken cabinet) – Understand how a circuit breaker works in order to know which part of it is faulty – Understand which devices use what circuits by noting their location and using common sense – Know how to test the circuit breaker and which part of it is faulty without having to look at its inner working (e.g. test all the switches, make sure that they are in place, etc.)
– Know how to repair or replace a broken wire or component – Understand what each device does (e.g. what a light switch does in the restroom, where this switch is located, how to turn it on and off) – Check the wiring diagram of each device in order to understand what components are used for (e.g. read a light switch’s schematic drawing)
– Know that a circuit that has power going into “A” and out of “B” will always have power in “B” even if you open “A”, since the wiring is double-insulated – Make sure that all wires and cables are properly insulated (e.g. make sure that there are no bare wires which could be tripped on) – Replace broken components with the same type of component (e.g. replace a light switch with a new light switch)
Since you’re a yacht engineer, you’ll likely need to replace electrical and electronic parts.
Yachts must have some sort of navigation equipment in order to find their way. The three most important navigation equipment are the chart plotter, the radar system, and the GPS system. All three of these devices can be found on any size or make of boat that could fit a water craft. All boats need at least two working systems per device as well as a spare when one fails. Many captains prefer to add additional equipment such as AIS, TargetX2, radar reflector, and DSC to be fully prepared for any eventuality when out on the high seas.
AIS allows vessels to identify other ships that may not be broadcasting a VHF call sign or an MMSI (unique ID) number. This allows for avoidance of collisions in areas where AIS is mandatory to use or when required by law. Also, AIS can help verify a number of regulated parameters such as exact speed. This set of competences is absolutely mandatory when you are looking for yacht jobs.
The chart plotter displays the boat’s position on charts and uses GPS data to pinpoint that location at any given time. The plotted path also gives a captain the opportunity to determine how far he/she is from a certain area or if sailing in an incorrect direction.
GPS, which stands for Global Positioning System, assists yachts to accurately determine its exact location and provides precise speed and position using satellites. GPS was initially introduced for use by commercial vessels but have since been integrated into personal use navigation systems. GPS equipment can be used in conjuncture with radar and the chart plotter to further navigate the boat. An additional feature on GPS is DSC (Digital Selective Calling), which will send a distress signal with the yacht’s exact position, if needed.
AIS, TargetX2, radar reflector, and DSC are optional but highly recommended when operating a yacht on open waters.
Today’s modern yacht needs to be equipped with GPS, chart plotter, and AIS. All three of these tools are a must when traveling on the high seas in order to avoid any accidents or mishaps along the way. Equipping a boat with these items can help prevent yacht owners from becoming victims of a maritime disaster.
ECDIS stands for Electronic Chart Display and Information System, which is a navigation system that uses electronic maps to show the position of the vessel. It can be installed on any ship or boat, and provides accurate information about the ship’s position.
ECDIS has many benefits associated with other high end technology systems like radar and GPS as it will generate a list of other nearby vessels. One additional benefit is that ecdis does not require visual contact with land or aids in order to accurately determine one’s location. The ecdis also has some drawbacks such as increasing fuel consumption, but with careful use can maintain accuracy while decreasing fuel costs by using an ecdis instead of traditional means to navigate through hazardous environments like fog, pelagic drift or ice.
Other methods of navigating a ship have been used for centuries, and ecdis is only the latest in technological advancements to make navigation safer. A few of these previous technologies include the use of sight by eye which can be inaccurate due to visibility as well as mathematical and geometric solutions such as using a compass or astrolabe. As technology advanced, ships started to realize the benefits of using innovative technology for navigation systems, and ecdis is a prime example of this.
This ecdis system consists of 4 main components: an electronic chart which displays information that is presented based on user preferences such as depth contours, shoreline information, port names and numbers and other navigational data including wrecks, obstructions and tide information. The ecdis can be connected to the ship’s autopilot or steering gear with a digital interface allowing for electronic communications between ecdis and the hardware.
The ecdis has two display options: one is an interactive touch screen that can be installed on the bridge of any vessel, whereas the second display option is an electronic chart that can be installed on a network along with other ecdis screens. The ecdis screen can also be connected to GPS, radar and gyro systems which adds further information about the surrounding environment like traffic, weather, hazards and narrow waterways.

2. The benefits of ecdis in comparison to other navigation systems
The benefits of ecdis in comparison to other navigation systems include ecdis’ easy integration between radar, GPS and the ecdis itself. Another benefit is that ecdis does not require visual contact with land or aids in order to accurately determine one’s location and has an increased probability of collision avoidance among vessels.
ECDIS also provides port information which allows for easier arrival and departure from ports, as well as providing information about the water depth at docks. The ecdis has an increased probability of collision avoidance among vessels and it increases safety at sea due to ecdis’ ability to provide real time information.

3. Drawbacks ecdis may have when used on a ship or boat
One drawback ecdis may have when used on a ship or boat is that ecdis increases fuel consumption. However, ecdis saves money by reducing the number of personnel needed to navigate a vessel manually, thus ecdis can save money in the long run. The ecdis also requires knowledge from users working with the ecdis system. Inacc
4. How ecdis was created and how its use has changed over time as technology advanced. The history of ecdis is long and winding, but ecdis first came into being in the early 70s after the development of microprocessors.
ECDIS was made possible thanks to several German IT developers who were engaged in a system approach for navigational data processing using computers. In addition, ecdis was also developed thanks to French engineers who were working on digital cartography, who also worked on the ecdis system. ecdis has been around longer than most people realize, and ecdis paved the way for modern day navigation systems like GPS.
However, ecdis has changed slightly over time as technology advanced and ecdis started to be used in combination with more recent technologies. For example, ecdis can now be used in combination with radar.
5. Other methods of navigating a ship that are still being used today, even with the advent of ecdis, manual method cannot be forgotten ecdis is only a complement to other means of navigating a ship or boat like radar and GPS. ecdis can also be used in conjunction with these older systems, but ecdis cannot replace them.
