About the Atlantic 23 Gade

With limited documentation available, the Atlantic 23 Gade represents one of the more elusive entries in the small sailboat market. This 23-foot vessel appears to be designed primarily for coastal sailing and day cruising, fitting into the popular category of trailerable weekend boats that dominated certain segments of the recreational sailing market. Based on its size class, the Gade would typically appeal to sailors seeking an accessible entry point into sailing or those wanting a manageable boat for local waters. The Atlantic brand name suggests European origins, though specific details about the designer and builder remain scarce in readily available records. Small boats in this size range generally offer straightforward sailing characteristics, making them suitable for both novice sailors learning the ropes and experienced sailors wanting a simple, responsive platform for recreational outings. The compact dimensions would make the boat relatively easy to trailer, launch, and maintain compared to larger cruising vessels. Without extensive documentation, potential buyers should seek out existing owners or sailing communities familiar with the model to gain insights into its sailing characteristics, build quality, and any particular strengths or considerations specific to this design.

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
17.51
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
10.15
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
2.52
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. 5.85
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. 559.33
