GPS Marine Navigation

The first question to be answered is:
What sort of sailing do you do?
Having answered this the amount of data you require from your marine navigation instrument can begin.
Racing Sailors Need:
- Boat speed
- Wind speed and direction
- Depth
- GPS data
Cruiser Sailors Need:
- Boat speed,
- Wind speed
- Depth
With a little help from space, you can get accurate fixes
However many boaters want the best of both, so why limit yourself to less information?
To help to learn more about the data received on your screen have a look at these definitions:
Boat speed:
is generated by the knot log or knotmeter. Once you know your speed you can start tweaking the sails to improve!
Wind Speed:
knowledge is generated from the wind instrument. This tells you the angle from which the wind comes. Throughout the information allows you to take advantage of conditions and adjust point of sail or choice of sail.
A transducer measures the distance between the hull and seabed. This helps with your inshore navigation
GPS Data:
This is a triangulated point of reference from satellites that orbit earth. Accurate within feet.
