I differ with Neal on this there may be some scatter on the deck of your
vessel but the main thrust of radar is focused much in the way light is with
a trouble lamp.

It goes out where it is pointed.
Unless you are in the bonsuns chair stairing into the horn!!
Then you will start to drip like a good humor in July!!
Holding the colregs up as some sort of disadvantage..... I believe the one
to avoid trouble first is the best of Captains.... The one taking liberty
because he/she can or is too cheap, will be an ex-scoundrel.... under the
ferry someday!!

The best way I believe is to set a safe perimeter on your radar to give
yourself enough time to manuver and plot around most obsticles. Plot stuff
that is pertinant in your field of interest.
Stay away from other boats and you dont need to plot!

Neal do you still have the 27 foot coronado?

Another thing to consider as well. According to the COLREGS
any vessel that has operational radar installed is required to
use it at all times when underway - even with unlimited
visibility. Do you really want to be washed with microwaves
the whole time you're sailing?

Then there's the COLREG requirement that in restricted vis.
if you have radar you must plot and ascertain the course of
all traffic you see on the screen. This is a lot of work and
very difficult on a small sailboat that is being tossed around
by any seas and wakes that may be evident. Once you do
get the coursed plotted it is up to the vessel with radar to
use that information to avoid a collision. This makes the
radar-using vessel a defacto give-way vessel where as
a small sailboat without radar can simply stand-on.

So, I'm wondering... For coastal sailing in LIS and very occasional
forays to
open ocean points north of there, do I need anything more than Furuno's
model
1623?

Need: If you're sailing in areas where you are doing night time or
occasional
sailing in fog, you could make points for and against radar.
Certainly, radar can make things easier.

Afford: You need to look at many things here, not the least of which, is
your
wallet, but you also need to know what you can afford to put on your
boat,
considering space for components and power requirements, coupled with
your own
comfort level of viewing and using the unit .... you may end up being
able to
go high end, or have to settle for low end .... only you can say.
Once you decide on a set (if you're thinking about it, you'll probably
end up
getting it), keep in mind that the installation, to suit your needs or
financial requirements, is only the beginning ..... now you need to
learn how
to use it.
My quess? 90% of those with small boat radar, get a maximum of 50% of
the
capabilities/ advantages, that a radar can give.
Between not knowing how to tune for conditions, not being able to
interpret the
display, not understanding relative motion and plotting, and thinking
that
since they have radar, they are now safe, a high percentage of those
with
radar, are more dangerous, now, than when they didn't have radar.
It's a great tool, but you need to understand it and know how to use it
..... if
you don't, it's a waste of money.
