Practice using the radar in good visibility. In Antarctica it is particularly difficult to use because of the floating ice, so a consistent radar watch is helpful, including a formal handingover between watches, so the new hand fully understands what is ice and what is land, and how it relates to the paper chart. Personally, we would never go to sea without paper charts, although the trend seems to be toward electronic images.
The fastest method for fixing position is to use the VRM to gauge distance off three distinctive points, then strike the arc on paper with a draftsman's compass to get a "cocked hat" fix. Radar watch alarms are a must for watching squalls, icebergs, or ship traffic.

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
