The quick verdict

The Oceanis 411 is a roomy, well-built family cruiser from 1997 to 2005 that sails well in moderate breeze but is slow in light air. Used asking prices in listings run from about $75,000 to $145,000. Before buying, have a surveyor check the forward cabin door fit, the rudder bearings and the stern tube.

Interior volume, easy handling and finish; Solid construction for a production boat; Extremely maneuverable under power; Good turn of speed under sail in breeze; Stable, comfortable cruiser for families

Not quick in light airs; Shallow draught limits windward pointing; Dark blue hull shows scuffs and scratches; Heavy for its size; Forward cabin bulkhead door hard to close or jams; Stiff rudder reported, with bearing wear; Stern tube problems, including a detached steel sleeve; Engine may need replacing
