This company supplies HD polystyrene.
You can see that they supply in Dow Surfboard foam at density 2.2 lb/ cu ft
You could choose a symmetrical foil and have the taper you chose, to make the top thicker - for the mast.
There are a range of aerofoils to choose from and you could make the wings tapered, but they only make them as straight tapers.
You can specify wing length, chord and thickness.

Thats a great site, I just pumped in some quick spec's for a mast and it came back w $14. That's an awesome deal.
Question, on the forward foil, are the high AR foils running w flat bottoms or semi-symmetrical?
