About the Atlantis 36

Designed by renowned South African naval architect Angelo Lavranos, this 36-foot sailboat represents a thoughtful approach to blue water cruising from the mid-1980s. With only 23 hulls built since 1985, the Atlantis 36 remains a relatively rare find in today's used boat market. The yacht's substantial 11,243-pound displacement and deep 5.91-foot draft signal serious offshore capability, while the generous beam of 11.35 feet provides excellent interior volume and initial stability. Lavranos configured the boat with a modern fin keel and spade rudder arrangement, offering responsive handling characteristics that balance cruising comfort with respectable performance. The masthead sloop rig keeps sail handling straightforward for shorthanded crews, making this an appealing choice for couples planning extended passages. With a capsize screening formula of 2.03, the Atlantis 36 falls well within the range considered suitable for offshore work, reflecting the designer's emphasis on seaworthiness over outright speed. The fiberglass construction and robust ballast-to-displacement ratio of 35% create a stiff, stable platform that should inspire confidence in challenging conditions. While not common in North American waters, those fortunate enough to encounter an Atlantis 36 will find a capable passage-maker built for serious cruising adventures.

Performance Ratios
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
173.87
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
21.01
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. 7.42 kn
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. 7.46 pounds/inch
