If you import a 21SC from the Houston area, I have a 21SC box I will throw in for free. Don't ask how I ended up with it in my backyard.

There were some similiar British boats built in the 70's -80's. I remember seeing pictures and thinking, how strange.

There was a British boat called a Strider(?) 20-21 ft like a Reynolds 21.

You could convert a H21 into a kinda of cruiser by building a custom (small) sail set and adding storage. A 10 wide H21 with a 240 sq ft rig would be real stable. Keep in mind those things are heavy 500-550 lbs.
