Radar - attitude changes

I cruised and raced for many years without radar, even once passing under the bridge on Eggemoggin Reach without ever seeing it in the fog. Then we bought our first serious powerboat 10 years ago which had a nice Raytheon unit already installed. We quickly learned to appreciate it at night and in inclement weather. Several years later I had another breakthrough moment while riding on the excursion boat from Boothbay Harbor out to Monhegan Island. That boat had the same type of radar with one additional twist. They could point at a target on the screen using a trackball, punch a few buttons, and get back an on-screen data box showing the speed, course and estimated CPA of the other vessel. Meanwhile the radar display drew a vector line on the display showing relative direction and speed of the target. I was immediately hooked and had to have one. Since we were about to buy a new electronics package for our trawler I made some inquiries about what was required. Depending on who makes your radar it is either called an ARPA or MARPA option. It adds a few boat bucks to the cost but is really useful and has given my wife the confidence to stand radar watches at night by her self. Priceless! |
