Going RADAR!
Hi,
Well, after thinking about it for several years, I'm biting the bullet and buying radar for Far Cove. I just want a Simple one that will tell me if a freighter is bearing down on me 2 miles away in the fog. So I'm getting the JRC 1000 - Steveston Marine has it for $1200. This weekend, I'm just gonna duct-tape(?) the antenna to the dodger or something, but I'd appreciate suggestions on where to mount on a 36ft sailboat. Mast? Or separate mast on the stern? Or should I get a "radar arch" and mount my VHF antenna, GPS antenna, radar, and solar panels on it? Also, where should I mount the display? I steer Far Cove from all over the cockpit, rarely from behind the wheel, so a pedastal mount may not be the best (maybe OK if it swivels...). And I'd have to remove it when I'm leaving the boat. Or maybe under the dodger? Lloyd Sumpter "Far Cove" Catalina 36 http://www.bcboatnet.org/ |

Some say the jury is still "out" regarding any harmful effects from exposure to radar at close range, but when it comes "in" it might be too late to do anything about past exposures. |

I have my new Furuno mounted on a mast bracket about 25 feet above the water which gives excellent range at a distance, and goes down to about 50 ft close in. I am very pleased with the overall performance. My old boat had the radar about 10 feet above water and I always regarded range as marginal even though it had a bigger scanner than the new one. |

Thanks for the input!

Or maybe under the dodger? Lloyd Sumpter "Far Cove" Catalina 36 http://www.bcboatnet.org/ The Furuno 1623 is twice the radar for about the same price. Just the better display alone is enough to put them miles apart. The antenna is a little better too. Maybe true (I do like my Furuno GPS31 GPS), but I need it for this weekend and Steveston's has a JRC in stock... As far as temporarily mounting the unit on your dodger... DON'T! The antenna needs to be mounted high enough that it's beam will not hit you unless you are at least 8-10 feet away. Putting it on the dodger means it will be burning what's left of your eyes to a crisp. Just forget it! Wait until you have it properly mounted. I was thinking of all the little hardtop powerboats I see with the antenna on the roof. Guess they don't run the unit unless they're in the cabin. How about a PVC pipe attached to the stern rail with a plywood plate on the top? Just long enough to get it well overhead. (I have to get it installed tonight) I have a tiller, so I mounted the display on a 1 foot square of Starboard that I can plunk down on the seat beside me. Sounds like my "sounderbox": I have a plastic box that has a sounder and GPS, (with rechargable batteries and solar cells on the top in the future...) that I use in my small boats. Everything I need close at hand... You also want the display close at all times because you will be needing to make adjustments on a continual basis. I have the cables coming up from inside a cockpit locker. I can move the display wherever I want it by feeding out more cable from the locker. When not in use, the display goes into the locked locker. I made a bracket that it slides into on the wall of the locker. Interesting arrangement. Do you have holes in your locker where the cables come out? I deal with fog frequently, and I also sail in heavy rain (Hey, if you don't like water, you really should find another hobby!) and at night. Hey, I sail the West Coast - donno how to sail if its not raining! I practice often during good visibility. I can sail into my harbor, find the channel, make the tight 90 degree turn between the two close rocks and make my way up the river to my slip on instruments only. I kinda do the opposite: try to avoid depending on electronics. (ie I use the GPS, laptop charts, etc. but still rely on compass and paper charts) Lloyd Sumpter http://www.bcboatnet.org |

One other thing: Am I correct in assuming if I have MY unit on, it shows up on other peoples radar's too?

The display should be mounted at the main helm area. All your electronics should be mounted in a central area. All displays should be removable and taken off the boat when you leave. How do you steer the boat from "all over the cockpit, rarely behind the wheel.."??? |

The vast majority of commercial fishing boats that I see are using Furuno's, and the day time visibility on mine is excellent, even in bright sunlight on the flybridge. The big crowd pleaser on mine however is the ARP function. It will track up to 10 targets simultaneously and display a speed and direction vector for each. For any one selected target you can get a data window showing target speed, course, closest point of approach (CPA), and time of CPA. Very useful running at night with seriously large shipping traffic near you, and that is when I most appreciate the longer range afforded by height. I've never tried threading my way between rocks 30 ft apart but have no difficulty resolving pairs of closely spaced channel markers at close range. Since the ARP function requires a digital heading sensor the unit has one other cool trick. It has a mode where the chart from the course plotter can be overlayed with the radar image. That function is particularly useful for quickly determining whether a radar target is a navaid or not. |

JRC makes good stuff. I picked up the 1800 a while back for Cruis'n
Rulz!. Killer radar. Just think, Lloyd, for another $400. you could have a color LCD and split screen CmapNT+ chartplotter, and twice the range.....
