CALLIOPE 405 Was conceived as a serious, self sufficient cruising yacht combining strength, beauty and sailing ability. The clients idea was to leave the UK, not necessarily to return. It is known she has cruised both the Caribbean and parts of the Pacific Ocean. Fully self sufficient having a substantial generating capacity. Ketch or cutter rigs; centre cockpit with pilot house for inside/outside steering.
