The problem for merchant ships is that small sailing vessels are just
hard to see. VERY hard to see. They usually present a poor RADAR
target and have dim or no navigation lights.

Could you tell us what is a sufficient RADAR target?
I found an old article:
http://www.ussailing.org/safety/Stud...eflector_2.htm
according to which my Mobri "does not perform well".

They say that in my area many commercial ships from a certain country do
not really keep RADAR watch, only listen to a possible radar warning
while reading magazines and having tea. Does that seem possible?

Where would you like the yachts to have their navigation lights?
Masthead or deck level? Masthead is seen from further away, but misleads
with regard to distance.
