Protect your marine electronic or Stacked While mooring

For some reason, when the time comes, it helps to know how to protect your electronics marine, while the detention or stack your boat. Anyone who has been around electronics for any length of time knows that one of the most common states after the discovery of an electronic problem is "that was working when it went out." A large percentage of failures occurred in electronics at the moment you switch it on. This can be attributed to a number of factors including exposure to moisture, abnormal voltages, static electricity, and temperatures extreme. When vessels are inactive for long periods of time of the incidents of electronic equipment failure seems to increase significantly. However, there are steps and precautions that owners, operators and technicians can take that can greatly reduce the potential for equipment failure that often accompany periods of non use.

Before entering today's electronics could be a good idea to play something else that ties directly into this topic. The battery system must be considered in the development of a plan or stacking mooring your boat. If you will not be operational (ie, pumps, fire systems …) during the down time then you should consider simply disconnect the battery fully. Anyway, should be fully charged before storage and not go more than several months without recharging. The best practice is to recharge the batteries before falling below a level of 70% load. Avoid extreme temperatures and prolonged exposure to moisture. An uncharged lead acid battery that allows the freezing damage may be irreparable. Make sure to fully charge the batteries before use. Starting the generator and convert the whole charging time of batteries is a bad practice and could result in equipment damage.

Indoors in a pot that contains the electronics, installing a dehumidifier is an excellent way to control condensation. Not only will it help protect your electronics, but a long way towards controlling corrosion in the wiring and connectors. In confined spaces where the installation of a dehumidifier not possible, using silica gel packs can significantly reduce moisture. Large gel packs are available that effectively cover several hundred cubic feet. Placing smaller containers in radar, satellite domes, and any other enclosed space, which houses the electronics is a very inexpensive way to help in controlling moisture. As mentioned above, the elimination of 100% humidity is impossible, but application of each method and tool at their disposal must be a top priority.

Another area of concern is the potential for damage due to static electricity, including the guy who is worse, a lightning bolt. Boats and all that stands of these are magnets for static electricity and does not take much to cause serious damage to your electronics. There is absolutely nothing you can do to prevent damage if your boat, or anything in it holds direct or indirect lightning. However, reducing the amount of static buildup on the antennas will reduce the likelihood of a strike. Even without a flash, simple static buildup the antennas and cables can cause potentially serious damage to electronic equipment. As with humidity control, take an active role in preventing of damage caused by static electricity and will be much better for him.

Longer and SSB VHF antennas that are configured on a lay-down are flat foot deck. Be sure to properly secure their "low" to maintain the position of being blown around by wind or disturbed by the rocking his ship. Disconnect coaxial cable at the end of radio prevent any static electricity that builds up in the passage of equipment. Labeling is never a bad cable idea. What is obvious today may not be as obvious a few months down the road. Devise a method of grounding the cable shield (outer conductor / braid) provides a constant flow path for all the electricity they are on their way to the wire. For those of you that I like that dot I and the T junction, shorting the center conductor of the coaxial cable shield of land that fall into this category. Obtaining a connector that mates with the one at the end of the cable can make the process earthing and short-circuit much easier. Bonds all the electronics to vessels of common ground (water) is also recommended. It is not necessary for their equipment is functioning properly, but it reduces the chance of static electricity and may also serve to reduce the paths of the leakage current flows that can promote electrolysis. metal-hulled vessels that this work very easy since almost everything is a good basis. However, the ships will not require significant hardware effort and attention when grounding. Volumes have been written on this subject so that's where I'll leave it for now.

Excessive temperatures can be devastating to electronics. Although most of the quality of marine electronic equipment manufacturing today is designed to withstand the harsh environment, reasonable precautions still make sense. Take steps to avoid direct exposure to light the sun for long periods of time. Lock windows and provide shade when needed. If your computer came with the addition of plastic caps, use them. Most of us have been around electronics enough to understand how damaging heat and prolonged exposure to direct sunlight can be. If you use the sense common and do everything possible to minimize exposure to extreme temperatures, your electronic equipment (and your pocketbook) will thank you.

Once is ready to revive the electronics after a long downtime are a few things to consider. The best to stabilize the environment before turning the computer on. Do not run the air conditioning on a summer day, hot or heating in winter and immediately turn on the electronics that are in the same area. That only promotes condensation that has been trying to avoid. Make sure the batteries are fully charged and visually inspect everything, including the antennas. Once they become electronics, give some extra time to radios and radar before transmitting. If you disconnected the antenna cables, but decided not to soil them, remember why you did it first. He tried to keep static electricity out of their electronics, so be sure to land the end of the cable before connecting it to discharge static electricity that may be on the line.

Although the main purpose of this article is for when The boat will be out of service for an extended period of time, some of the practices and procedures here can be applied to everyday activities, care and maintenance of your electronics. Not all failures can be avoided, but with a better understanding of your computer and the application of some relatively simple procedures, you can go a long way toward extending the life of your electronics and save a lot of money. Smooth Sailing.
