About the Deltania 27

With limited documentation available, the Deltania 27 represents one of the more elusive entries in the 27-foot sailboat category. This relative obscurity suggests either a small production run or regional distribution that didn't achieve widespread market penetration during its era. Based on typical design conventions for boats of this size class, the Deltania 27 would have been conceived primarily as a coastal cruiser suitable for weekend adventures and day sailing. The 27-foot length positions it in the popular small cruiser segment that emerged as manufacturers sought to balance affordability with basic accommodation needs for couples or small families. While specific design details remain sparse, boats in this category typically feature modest cabin layouts with basic galley facilities and sleeping arrangements for four. The emphasis would likely have been on straightforward sailing characteristics rather than racing performance, making it accessible to recreational sailors seeking an entry point into cruising. The scarcity of available information makes the Deltania 27 something of a curiosity for boat researchers. Potential buyers considering this model would benefit from thorough individual inspection and surveying, as owner experiences and maintenance histories become particularly valuable when manufacturer support and parts availability may be limited.

Performance Ratios
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
22.86
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
135.18
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
15.82
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. 6.68 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. 4.5 pounds/inch
Rig Dimensions
I (Foretriangle Height) 1.48 ft / 0.45 m
P (Mainsail Luff) 301.39 ft² / 28.00 m²
E (Mainsail Foot) 7.28 ft / 2.22 m
