[1][3] The Edel 665 is a small recreational keelboat, built predominantly of fiberglass, with mahogany wood trim.

It has a fractional sloop rig, a raked stem, a vertical transom, a skeg-mounted spade-type rudder controlled by a tiller and a fixed fin keel.

[1] Features include a lifting eye on the keel to facilitate winching the boat in and out of the water with a crane, opening foredeck hatch, a mainsheet traveller and genoa tracks.

Accommodations can sleep four people on a "V"-berth, a convertible settee and quarter berth.

Factory options included jibsheet winches, a hydraulic "pop-top", a recirculating head and a spinnaker.
