Castle 650
Description
The Castle 650 is a popular Australian trailerable sailboat (often called a trailer sailor or trailable yacht) with a fractional sloop rig, lifting keel (lead daggerboard for better efficiency than typical iron), and pop-top cabin for standing headroom when raised, designed by Steven Douglas (an Australian naval architect known for performance-oriented small boats in the trailerable class), built by Yachtworks (Mordialloc, Victoria, Australia) starting in 1980; production has been ongoing or intermittent since then (still referenced in active class associations and recent sales), with hulls constructed in fiberglass for lightweight yet durable performance; quantity manufactured is around 120 (per SailboatData and builder/historical reports, though some sources suggest up to ~200 or fewer due to limited large-scale output and class rules tracking).
