From my table of radar performance 10 ft from the waterline gives you a 4 nm range to a buoy


Whereas the 20ft up the mast option gives you over 6nm.

A radar guy from the airforce said the wires break down from metal fatigue over time.

"A radar guy from the airforce said the wires break down from metal fatigue over time. "

I can see that happening just when the radar was really needed! That is a good enough reason to go with the fixed mount.

If you sail single handed without Radar or AIS, this looks good to me, low power consumption and a buzzer to let you know you've been painted.

EchoMax Radar Reflectors -EchoMax Products

The usual disclaimers.

False sense of security. This device and the other similar one work on a single frequency band used by merchant ships for coastal navigation. Most merchies use a different frequency band radar when out of sight of land, and this device does not work on that!

Gross Negligence is intentionally undertaking an unjustifiable risk, such as deliberately going to sleep, when in command of a vessel.

According, I suspect that the Lawyers amongst us might make a prima facie case that even undertaking any significant voyage single handed is grossly negligent.

There are those who take chances, then there are those who refuse to live, but simply choose mere existence.
Living by the dictates of lawyers is living ones life in an ever tightening straight jacket.
Who elected them to rule over us?
What do you calll a lawyer with an IQ less than 50? "Your Honour."

Brent,
Very well said, thank you.

unfortunatly, we elected the lawyers to rule over us, we changed their title to politician.
As I quoted before from Pogo's comic strip: "We have met the enemy, and it is us"

John

Isn't there a "large vessel signal simulator" that can electronically make a small sailboat appear on a merchant's vessel radar like a large "something" that needs to be avoided?

sleeping at sea

Hi All well first things first. Admiralaty rukes for officer of the watch. If the officer of the watch is found to be asleep on watch he shal be hanged by the yard arm.

Now the good news I saw on the net yesturday that the makers of the AIS system are now offering an AIS transponder for yachts that works just like the ones on merchant ships. It sends a signal just like they do which shows on their AIS receiver and their radar. If you cant find it on the net I will try to find it again for you.
Regards Pete
