With so many similar models on the market, it is sometimes rather hard to pick the right fishfinder GPS combined unit. There are several important features which one has to consider when buying such unit, including personal preferences and of course, the budget. Buying the most expensive one in the nearest store is rarely a proper solution ...
Newport Vessels NV-Series of saltwater/freshwater electric trolling motors ranges between 36 and 86 pounds of thrust and is excellent choice for most of the applications where such propulsion is required.
These motors are lightweight, affordable, come with many features required for safe use and are easy to use. If you need such motors, consider these electric trolling motors as one of your possible choices.
Marine lead acid batteries are still going strong as main boat battery, for trolling and similar, but in many circumstances they are replaced by other types of batteries.
Jump starters are devices that enable one to 'jump start' the internal combustion engine, when the main battery (or battery bank) fails.
Regardless if it is boat, car, lawn mower, forklift, truck or any similar vehicle, jump starters can be of great help.
Fish finders are often used on kayaks and small one- or two-man boats and choosing right battery with maximum performance and minimum weight at acceptable price can be confusing thing to do.
When describing features and performances of marine and automotive batteries, cables, generators etc. many abbreviations are used commonly. Knowing these abbreviations is of ultimate importance for understanding what one unit actually can and what cannot do. Here is the list of the most common abbreviations used on our site.
With various standards around, it is important to know how to convert proper cable sizes from one standard to another. Also, voltage drop and power losses depend on the cable length, thickness and current flowing through the cable.
Warning: no math in this article, seriously :)
Electrical demands on modern boats are much higher than decade or more ago. Nearly all fishing boats have electrical devices such as lights, radios, sonars, refrigerators, laptops, electric trolling motors, electric watermakers etc.
Electric golf carts use deep cycle lead acid batteries as energy source for their motors.
Selecting the right battery can be daunting task, especially with lithium batteries being more and more present in everyday life.
Marine battery boxes, trays and mounting kits enable placing and storing of the marine battery and its use in a safe manner.
During the operation, battery or battery bank should be kept safe, with an easy access if and when required.
Marine battery monitors are simple electric and electronic devices that monitor various parameters of marine battery and display them in a simple and readable manner. Built-in alarms can warn the user that certain parameters are out of desired range and can save the day. And often much more ...
Electric trolling motors are commonly found on smaller and medium boats for propulsion during trolling. When compared with internal combustion engines, they have both pros and cons that one must be aware of.
Mains chargers allow the batteries to be charged while the boat is in the port. Also, when in use, these chargers power entire boat's electric grid - lights, electronics, refrigerators etc.
Since larger boats can operate in different areas and in various countries, it is important that these chargers accept various voltages (110V, 220V, 380V), phases (single-phase or three-phase electric power), various sockets etc.
Solar panels convert sunlight into electricity. Their power output depends on many things like sun radiation strength, angle of the solar panels, their type and age.
Unlike wind turbines, they have no moving parts, they produce no noise during operation and can be positioned more closely to the passengers and onboard equipment. They operate during the day, but during the night, they produce no electricity.
Wind turbines harness the energy of the wind. Blades are connected to the shaft that is connected either directly or over transmission box to the electric generator.
Wind turbine generators start to produce electric energy even during low wind speeds, but no wind, no electricity.
Fixed or portable diesel or gas generators are commonly found on medium or larger fishing boats when electricity is in demand.
They have low fuel consumption, relatively low noise levels, can be easily repositioned (at least portable versions), for example, on-shore when required, or transported for maintenance etc.
Manual power generators provide power to the most basic equipment in need - radios and radio beacons, cell and smartphones, navigation lights and similar.
They provide tens of watts of power and they are not suitable for charging the main boat battery - while able to provide 2-3 Amps, they would require 10 hours to charge the 12V battery with 20-30Ah.
Electric systems commonly found in fishing and recreational boats are very similar to the electric systems found in recreational vehicles (RVs). Boat and RV batteries must power various devices ranging from tablets and smartphones to refrigerators, TVs, microwave ovens, AC units, etc. when main engine(s) are powered down and not producing electric energy.
Such batteries also must supply enough energy to avoid issues with power spikes when the RVs are powered via solar panels and/or wind turbines and some larger unit is turned on.
100 Ah AGM batteries provide best balance between size of the battery in terms of mass, capacity, reserve capacity, cranking amps and of course, the price.
These batteries are commonly used as cranking batteries for smaller gas and diesel engines, as dual purpose batteries in electric systems where they are used as both cranking and deep cycle batteries for powering the electronics, pumps, lights and similar devices, and in the end, as deep cycle marine batteries for powering various electric and electronic devices, including electric trolling motors.
