Marine GPS’s are very similar to a Outdoor GPS the only difference is that it is based around the water, it shows things like docks shipping lanes and navigation markers. You can place your own way points for fishing spots and so on as well, there is usually very little data on land based locations on the units, they also tend to give you Marine units of measurement such as the Knot instead of Km/h
