Illusion class

The Illusion is a one-design keelboat, based on a scaled version of Lionheart, the British 12 Metre Class yacht and designed by Jo Richards and Neil Graham in 1981. These peformance single-handed boats offer superb racing in nearly any conditions, by sailors of all weights and ages - with tested racing performance up to Force 6! Boats are equipped with a standard main, roller furling genoa and spinnaker, plus running rigging
