I won't waste brain cells getting involved in the theoretical part of this conversation other than to point out that all the stuff that MIGHT reflect, rather than scatter radar
beams on your boat, other than the mast
, is how high above the surface of the water
? How many meters of freeboard do you have? This is going to do Sweet Fanny Apple for you if you are hull
down in a seaway, lost
in the swell, don't you think?
That just leaves your mast
, and as others have said, if you are heeled, the surface of your mast looks a lot like the side of a stealth aircraft. I somehow doubt you're going to get a good radar
reflection off that.
I have a great big fender-shaped passive radar reflector at about the level of my third spreaders, so probably 60 feet above the water. I know from talking to the bridges of different ships (I sail in the busiest shipping
lanes in the world, so have plenty of opportunities to ask) that I am well visible from 10 miles off plus, heeled or not. I feel pretty sure that that's not the reflection from my davits
rollers, they're seeing from 10 miles away, when they are still hull-down to me.
Of course if you are transmitting AIS
the whole conversation is probably moot. I'm installing AIS
as we speak, but I still don't think I'm going to take down my radar reflector. I couldn't do it, anyway -- radar reflectors are required for UK flagged vessels of any size.
