[1][2][4] The Sovereign 20 is a recreational keelboat, built predominantly of fiberglass, with wood trim.
It has a masthead sloop rig; a spooned, raked stem; a plumb transom; a transom-hung rudder controlled by a tiller and a fixed fin, shoal draft keel.
[1][2] The boat is normally fitted with a small 3 to 6 hp (2 to 4 kW) outboard motor for docking and maneuvering.
We think that as new boats they were grossly overpriced (particularly near the end of their production runs); they were poor sailers relative to their comp[etitor]s; and their marketers made wild claims.
A quick look at the specs ... shows that except for her two-foot fixed keel, which effectively ruins whatever upwind sailing performance she might otherwise have had, she is very similar in size and weight to her comp[etitor]s—all of which sail better than she does, are easier to handle at a launching ramp, and cost a lot less to buy when new.
