Designed by Dixon Yacht Design and built by Saturn Yachts Ltd. in the UK from 2010 onwards, this 45-foot cutter represents a thoughtful approach to modern cruising yacht design. The Saturn 47's generous beam of just over 14 feet provides excellent interior volume while maintaining seaworthy proportions, making her well-suited for both coastal cruising and offshore passages.
The fin keel with rudder on skeg configuration offers a good balance between performance and directional stability, while the substantial displacement of over 24,000 pounds ensures comfortable motion in seaways. Her comfort ratio of 26.47 suggests she'll provide a stable, predictable ride for extended cruising, though she won't be the fastest boat in light air conditions.
The cutter rig configuration is particularly noteworthy for cruising sailors, offering excellent versatility in varying wind conditions and the ability to balance the sailplan effectively. With a capsize screening formula of 1.94, the Saturn 47 demonstrates good stability characteristics appropriate for offshore work.
The fiberglass construction and relatively recent introduction to the market mean these boats typically feature modern systems and layouts. Her 8.54-knot hull speed indicates respectable passage-making potential for serious cruising sailors seeking a capable, comfortable platform.
Displacement/Length
Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy

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.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore

Capsize Screening Formula
The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended

Hull Speed
Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions.

Pounds/Inch Immersion
Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline.
