Need?
Ed,Maybe "need" is the wrong term. I sailed Long Island sound and the islands for 16 years without radar. Yes, there were times that I wished for radar, but I never bought it.However, I now have a Raytheon RL70H 4KW unit on my 40.5 that I keep in Westerly, RI. I use the radar all the time, and I consider it a very valuable tool.I purchased it before a Maine cruise so I could deal with the legendary fog. However, now that I am used to having it, I would always want it.In addition to seeing other vessels, it can be used for thunderstorm watchs and tracking rain cells that are in your area. Interfacing to your GPS will allow your waypoint to be plotted on the radar screen. This is a really neat feature since it helps indicate which of the targets on the screen is actually your intended point.Why don't you talk to Fred at Dockside Electronics at the Noank Shipyard. He has demos set up with different equipment. If you wish more info on installation of the radar, or if you want to see my system in person, email me.Rich
