[1][3][4] The Edel 820 is a recreational keelboat, built predominantly of fiberglass, with teak wood trim.

It has a masthead sloop rig, a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a wheel or tiller and a fixed fin keel or stub keel and centreboard.

Some boats have been retrofitted with a small outboard motor in place of the inboard diesel, for docking and maneuvering.

The galley has a two-burner gimbaled propane-powered stove an ice box and a manually-pumped water system.

There is also a navigation chart table and a head with an 18 U.S. gallons (68 L; 15 imp gal) tank.
