LOL I'd say that ended years ago. I've seen some smaller yachts with better
equipment than larger ships.

Motor yachts maybe but sailboaters don't have a clue.

I've seen many a radar on small sailboats that the owners
brag about and these units are more suited to big ships than
yachts, especially sailing yachts that heel.

Sailboaters are stupid when it comes to choosing radar.
They favor the wrong features. One example is the range
they choose. Booby is a good example. He keeps his
unit on 24 mile range so he can keep track of thunder
storms while he should be using 1/4 mile range to keep
track of things that will affect him sooner rather than
later. Big and powerful is really stupid for a slow speed
boat that heels. Small and accurate at close range is
what a sailor really needs. Radar also needs to be
mounted high up - the higher to better so it can 'look
down'. This isn't possible on a sailing yacht because
the higher up the worse the heel. You end up with a
gimballed mount lower down that's garbage.

My wife doesn't. She doesn't use the mirror at all! She recently
reversed into the bloody house - and broke a rear light!!

25 years ago, I tried to teach her how to drive. Geeeze, that was a
disaster! We had a MAJOR row after she refused to look in the mirror before
pulling out into the road. She *knew* that there wasn't any traffic because
it was a quiet Sunday afternoon.


After that, she got a driving instructor.

Simple Simon wasn't doing too bad until he got down to:

Look down? First of all, if you mount too high you can see over close in things - at the
top of a 0 foot mast, you'll miss small buoys 250 feet from the boat. Second, higher up
you'll get more sea clutter.

This isn't possible on a sailing yacht because
the higher up the worse the heel.

Are you saying the heel angle on your mast is more higher up? I thought only my old
Nonsuch did that!

You end up with a
gimballed mount lower down that's garbage.


I think some of them are too low, and I don't like having it on the stern, but I don't
think thy're garbage.

Gawd you're funny!! You don't have a clue as to what's going on, on the
bridge
of a ship, do you?


I do, too - ask me anything.

S.Simon - a Captain who knows plenty enought to really worry
the tugboat captains.


Never been a tugboat Captain ..... not qualified.

What watch does the Captain stand?
Who is the designated "Navigation Officer"?
Who steers the ship at sea .... in port?
What are the 3M's duties?
Who maintains the radio log?
What is a deadmans switch?
How many whistle controls, on the bridge?
How many EOT's?
How many methods of steering on the bridge?
What are "Noon slips" and how many are there?
Who keeps the Bell Log?
What's in a Bell Log?
How often do you have to wind the course recorder?

G just a few, Neal .... let's see how you do

That's a relief.

Why? Were you worried? Feeling confused?

ROFL .... Your lack of knowledge in another area, is screaming at us.
At sea, there is nothing wrong with using the 24mi range (though I'd admit for
his size boat, that's a bit far). You can still see targets that are closer to
you, so you can easily shift your range down for a better view .... course,
that should be a normal procedure.
Normally for Boobie, I'd suggest, in the Sound, running on the 6 or 12 mile
range, depending on conditions and what his major use is. Minimum would be 3
miles, shifting to lower (1.5 or 0.75) for a closer look at a particular target
for short periods, but NEVER leaving his radar at 0.25 mi, unless he was doing
some close in navigation, within a harbor area.
You always want to be on the longest range that allows you the best overall
picture of your area, be it traffic or navigational.
Whenever you switch to the real low ranges (0.75mi and below) you are creating
a situation of "tunnel vision" and Highly limiting your overall view of
surroundings.
Are there times that you want to be on these lower ranges? Of course, but,
these are normally only within harbor areas, or close situations in fog
(traffic) or close navigation problems .... even then, stay on the higher range
as long as possible (question of G spatial awareness).

Radar also needs to be
mounted high up - the higher to better so it can 'look
down'. This isn't possible on a sailing yacht because
the higher up the worse the heel. You end up with a
gimballed mount lower down that's garbage.

Frankly, I think you should have left is on so that you can learn more about
radar, while
Suzy learned the serious stuff.

We had quite a messy bit of sea coming in and my hands were full. Suzanne had
the nav down right. The radar was on standby and not needed.

Just out of curiosity .... What's the whistle signal, if any, to open a
draw bridge, in your area?

I haven't seen this... most units are about what you would find on a

I generally keep mine to about the 2 mile range... that's plenty of warning.
I'll drop to a tighter radius if in close proximity to shore. I have mine
mounted just above my Steaming Light /Deck light fixture on a ridged mount.
I found it operates well to 15 degrees heel even in rough water and showers.
Even in a storm it consistently showed a minimum of 4 buoys in a line of 10
buoys that delineated the foul ground from safe water. I have an older model
Furuno with CRT screen and 16 mile capability. I hardly ever use it beyond
the 8 mile range. When the guard zone alarm is set... the buzzer that goes
off will wake the dead. It has picked up float planes and a wooden 18 foot
sailboat miles off. We even used it to locate a missing inflatable dinghy
with the kicker still attached one dark night after it snapped it's painter
on my friend's boat which was accompanying us on the trip.

I like my radar....
