A friend of mine just bought a Dix boat, and it looks like a great
boat. It's had a lot of sea miles and is still in good shape. Lots of
clever design features as well.
You can get CNC cutting files from for this boat from Dix .

This is a cutter rig, not a sloop, BTW, but sails fine without the
staysail.
