About the Young 12M

Produced by Young Boats, an Australian builder with a long-standing reputation for crafting capable and accessible sailing vessels, the Young 12M is a cruising yacht that reflects the practical design philosophy the brand became known for across the Australian market. Built with family and club sailing in mind, this boat strikes a balance between comfortable offshore capability and manageable day-to-day sailing, making it an appealing option for those looking to explore coastal waters or participate in local racing events. The Young 12M carries the hallmarks of a well-rounded cruiser-racer, offering enough performance to keep sailing engaging without sacrificing the livability that weekend sailors and cruising couples tend to prioritize.

Prospective owners are encouraged to seek out individual vessel surveys to assess condition and any modifications made over the years.

Performance Ratios
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
17.1
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
