I don't know if the aluminum layer in a CD is thick enough to reflect a radar signal...given that the mast on a sailboat does a pretty piss poor job of it, and is generally much thicker aluminum... BTW, the reflective layer is aluminum, not silver. Silver is probably a better radar reflector than aluminum, as it is a heavier element. Lead is probably even better.
Granted, angle of reflectance matters, and corners seem to generate a much larger return than smooth rounded surfaces...I'd still go with a Davis Echomaster over a pile of AOL CDs—but they might work if glued in a shape made of multiple tetrahedrons...

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
