Question: What is your preference regarding the best place to mount a radar antenna? As far as we can tell from the pictures of Morgan’s Cloud you have mounted yours on a pole aft. Our previous experience with radars tells us that the antenna should be as high and free as possible. Wouldn’t a radar antenna mounted on the mast just above the first spreaders give better range and a more detailed radar picture than if it were mounted lower? It also appears from the pictures that your antenna isn’t mounted in a way that makes it able to tilt so that it can compensate for heel of the boat when sailing. Answer: First off, we should say that we view radar as the most important piece of electronic equipment on Morgan’s Cloud—yes, more important than GPS, since we can find our way with a compass and sextant but we can’t see unlit objects at night or through fog—so we have given a lot of thought to the position and installation of our radar scanner. We prefer a pole mounted aft for the scanner over mast mounting.

Converting cave survey notes into a finished map With a set of cave survey sketch notes in hand, the next steps for converting those notes into a beautiful and accurate map can be daunting. Some cave cartographers spend more time in front of a computer screen than they do underground. Historically survey data was compiled with a calculator, and maps were drafted on mylar sheets with pencil and rapidiograph. Virtually everyone today is using cave survey data management and digital drafting software for the improved efficiency, quality, and ability to make changes and updates. In most cases the data management and drafting are handled by different applications. I recommend developing an efficient workflow for handling new survey data.
