Sand under raised beds?

I have a large sandy spot in my front yard in central Maine. Since I
need more garden space, I'm thinking of building raised beds over the
sand. Nothing will grow there anyway and I'm thinking a sand base would
allow the raised beds to drain well.
As Dan has also posted, raised beds drain extremely well already. On
top of that, voles like them, increasing drainage further. If you then
add coarse organic matter they will drain so much you will have to
water every day at least.(all this from personal experience). Here is
my advice:
1) make sunken beds in the sand. Dig up the sand, replace with fine
organic
material only, so that the beds are slightly below the sand.
2) mulch heavily to above the sand line with coarse organic material.
In time
your beds will grow higher than the sand, as the mulch composts, so
start
6 inches below at least. Bad for your back but good for your
veggies. I wish
I had done this when I made my beds in my sandy soil. My in laws
have sandy
as well, they have sunken beds in full sun, and their productivity
is far
higher than mine.
Is this a workable idea?
Thanks for any advice.
I live by the beach and had tried to grow veges with not much success.
I laid down polythene, then old carpet on top of the sand and used
compost, grass clippings, recycled potting mix from a farm, basically
anything I could get, and made a new garden all together, and now have
veges growing like theres no tomorrow. Found that when i added stuff
to the sand, the sand would just keep coming back.
