About the Deltania 25

Launched in 2020 by German builder Deltania Yachts, this modern 26-footer represents a fresh approach to coastal cruising and day sailing. The fiberglass construction combines contemporary design elements with practical features that appeal to both weekend sailors and those seeking a capable small cruiser. The swing keel configuration stands out as the boat's defining characteristic, offering exceptional versatility for sailors who want to explore shallow waters, launch from trailer ramps, or find protected anchorages inaccessible to fixed-keel boats. When raised, the keel allows access to shoal waters and simplified trailering, while the deployed position provides adequate stability for coastal sailing. With a fractional sloop rig and moderate sail area, the Deltania 25 balances performance with ease of handling. The sail-to-displacement ratio suggests spirited performance in light to moderate conditions, making it well-suited for day sailing and coastal cruising rather than serious offshore passages. The capsize screening formula indicates this boat is best kept in protected to semi-protected waters. The outboard rudder design enhances maneuverability and simplifies maintenance compared to inboard systems. For sailors seeking a modern, trailerable cruiser with shallow-water capabilities and straightforward systems, the Deltania 25 offers an appealing package for coastal exploration and weekend adventures.

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
19.94
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
174.85
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
16.62
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. 6.29 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. 3.9 pounds/inch
