Other than manual vs automatic tuning, I think there is very little difference between older vs newer radars.


I think the issue isn't the model radar on your dash, it's your willingness to learn how it works.

They apply inland too....slightly modified from offshore.

The Inland Rule 7(b) governing the use of radar that is fitted and operational is identical to the COLREGS.

I'd rather have a 30 year old radar that works than a receive only AIS. THE MANUAL will tell you how to set it up, but you need to use it often to be able to use when its really needed. It's not hard.
One thing I see from your signature photo that may give you trouble is the canvas top bows being in front of the radar. This will cause strong echo returns to stretch out from distinct "blips" to partial circles. Again a simple reduction in GAIN will pick the target out of the noise. On the older sets, its a knob, like turning down the volume. On the new radars, its a menu item that you need to be able to find on demand. As others said, the time to learn to use radar is in clear weather.

Modern doppler radar simplifies radar. I have a Garmin 18 fantom radar on my boat and have it on continually even in the sunniest, clearest day of the year. It will track 10 targets in your area that are closing with you or are close to you but not a threat. The target has a tail with a dot at the end. If the dot is green, no threat, if the dot is pink, pay attention but not a threat, if the dot is red, the vessel is closing on you and is a threat.

Garmin's radar is designed for people who don't like manuals and just want to stumble around until they figure it out. I like it because I don't have an autopilot. When my guests come on and ask if I have an AP I say yes - you. So I can take a radar illiterate, plunk them down at the helm and tell them about target acquisition and colours, and ask them to tell me when any target is red, and we are good to go.

For me, one of the main functions of my radar is to let me know what is behind me. I find I and my guests just don't many head checks to the stern. This way some fishing boat with 4 outboards can come screaming by and not startle me. I will see it on the radar.

BTW, not meant as a criticism, but add me to the list of the someones who would never have anything larger than a ski boat without functioning radar of some sort. I was brought up on analog radar but appreciate modern units. I’m always amazed at those willing to boat in the dark without the proper tools to keep the boat on the right side of the water surface.

Toocoys, on another note. You mentioned replacing your radar display with remote engine monitoring camera. That seems like a huge waste of money for your type of cruising.

He says he's gone for now. We will see.

While I understand but don't agree with his concept of radar for his cruising style, (if`day, fair weather, limited cruising) is all he plans to do and is good at monitoring weather and sunset, I would agree that remote cameras are a wonderful tool.

My take is that radar is just another tool in our navigational toolbox. There will (may) be times when it's helpful, and others when it's not. Just like using a chart plotter instead of paper charts, there's a leaning curve, and still a place for each.

Well, if one doesn't care about nav rules, then I can see how a radar would add very little value.

This.
Someone earlier posted that he/she should get a houseboat. Myself and others initially thought the comment out of hand. But anyone who feels they can disregard the rules of navigation should never leave the slip. Just my $.02.

You asked about the usefulness of radar and got many helpful answers. You scoffed at colregs and received some legitimately critical comments. Now you quit and go home?

You are acting like a kid looking for attention. Be a grown-up and have a discussion. You might learn something.

There are some large container ships that make a very large and potentially damaging wake. I can see those wakes trailing the ship on radar and have plenty of time to prepare for them.

Here's an example of how radar can help. I was anchored in a cove on a beautiful sunny day when the wind changed direction 180* and started howling. I raised the anchor and headed toward our marina which was about 5 miles away. This is the view we had as we were coming out of the cove.


I could see a small boat headed toward us from about 3/4 mile away. I knew I was not going to be able to see when that rain hit us so I flipped on the radar. It timed in just about the time the rain hit.

We slow cruised along the lee side of the river as we headed home. I couldn't see 50 yards but the radar kept track of that other boat even as it passed us.

About 3/4 of the way home we took a lightening strike that blew out all the flybridge electronics and the winds ripped up my upper bimini. I found out later that the winds were clocked at 70+mph.


All of this happened on the Columbia River, with no open waters anywhere around. Never underestimate the need for a radar. You never know when it's going to be needed.

I've got the same Garmin (first time radar). I haven't stumbled around using it enough to get the color-coded tracks on radar targets. I do get irritating warnings when an AIS target is headed "at me" (even if there are 10 finger piers between us). I also saw something invisible ripping up behind me and passed really close. Turns out it was a cormorant at about 20 foot elevation.

Some of the safety features remind me of Mrs. Bucket in the British series Keeping up Appearances. "Mind the lorry, Richard." "It's parked over in the lot, Hyachinth." Still, I need to learn all the system can do if only to figure out how to turn things off.

Somebody mentioned a book on radar usage (since the Garmin manual is useless). Any suggestions?
