Marine instruments enable the sailor to measure and plot various aspects of his on-the-water experience in real time. Typically these include performance indicators such as wind speed and direction, boat speed and heading, and depth. More sophisticated systems can then take these basic measurements and calculate and display additional information such as true and apparent wind speed, course over ground, speed over ground and much more. Marine instruments are generally a combination of sensor, processor and a relatively small display unit or dial which can be mounted both above and below deck.

Prices and capability vary widely depending on capability. Top end systems can interface with sophisticated tactical software programs to use the performance data to calculate the most efficient way to navigate a race course in any set of prevailing conditions.

Good quality marine instruments are rigorously tested to withstand all environmental and climate conditions. They are silicone sealed to guarantee water tightness and come with sun protection covers to reduce glare and prevent over-heating. These unobtrusive yet essential instruments are generally easy to install in any type of craft and sailors find them invaluable - whether sailing, motor cruising, fishing or racing.
