In other words, if you took $50 of aluminum foil crunched it a bit and wrapped it around 5 huge cardboard boxes that were used to ship refrigerators, and then hoisted that aloft, it would probably relfect about as well as the modern $50 reflector - and maybe not.

It's $50 well spent and you may even be able to pick one up on eBay or Craigslist for cheaper than $50.

This looks like a useful article. It's about radar reflectors for kayaking - but I imagine that the info would be comparable to sailboats (just the ranges would be longer).

It seems as though the tin-foil hat I wear anyway would also work to reflect radar...

Visualize the vastness of the oceans; the infinity of the heavens; the fickleness of the wind; the artistry of the craft and the frailty of the sailor. The oneness that may be achieved through the harmony of these things may lead one to enlightenment. - Flying Welshman
