About the Deltania 20 5

Designed by Andre Skrzat and built by German manufacturer Deltania Yachts from 2006 to 2015, this compact cruiser represents thoughtful European engineering in the trailerable sailboat category. At just under 22 feet overall, the fractional sloop rig and fiberglass construction deliver a capable platform for coastal sailing and weekend adventures. The swing keel configuration stands as the boat's defining feature, allowing access to shallow waters while maintaining sailing performance when fully deployed. This versatility makes it particularly appealing for exploring protected bays, lakes, and coastal areas where fixed-keel boats cannot venture. The substantial ballast-to-displacement ratio of approximately 30% provides reassuring stability despite the compact size. With a sail area to displacement ratio of 20.09, the boat offers spirited performance without being overpowered, making it suitable for sailors transitioning from smaller dinghies or those seeking manageable cruising speeds. The beam of 8.2 feet creates reasonable interior volume for overnight accommodations while maintaining trailerable width. The capsize screening formula of 2.44 indicates this design is best suited for protected waters and coastal sailing rather than offshore passages. For sailors seeking an easily transported boat capable of comfortable day sailing and occasional overnight trips, this German-built design offers European build quality in a practical package.

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
 20.09
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
 166.01
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
 11.48
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. 5.79 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. 3.28 pounds/inch
