Dehler 25 Fin keel

Sailboat specifications

The Dehler 25 is a 24’11” (7.6m) cruising sailboat designed by Van De Stadt Design (Netherlands). She was built between 1984 and 1995 by Dehler (Germany). The Fin keel version adopts a classical fin configuration, the easiest option to provide a low center of gravity.

The Dehler 25 is as well listed, on Boat-Specs.com, in Centerboard (Trunk) version (see all the versions compared).

Dehler 25's performances

Upwind sail area to displacement iThe ratio sail area to displacement is obtained by dividing the sail area by the boat's displaced volume to the power two-thirds. The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size. Upwind: under 18 the ratio indicates a cruise oriented sailboat with limited performances especially in light wind, while over 25 it indicates a fast sailboat.: 315 ft²/T29.28 m²/T
Downwind sail area to displacement iThe ratio sail area to displacement is obtained by dividing the sail area by the boat's displaced volume to the power two-thirds. The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size.: 497 ft²/T46.17 m²/T
Ballast ratio iThe Ballast ratio is an indicator of stability; it is obtained by dividing the boat's displacement by the mass of the ballast. Since the stability depends also of the hull shapes and the position of the center of gravity, only the boats with similar ballast arrangements and hull shapes should be compared. The higher the ballast ratio is, the greater is the stability.: 34 %
Righting moment @ 30° iThe righting moment is a moment (torque) that tends to restore a boat to its previous position after heeling. Its value corresponds to the torque needed to heel the boat for this angle. Higher the righting moment is for an angle, greater is the stability.: 5786 lb.ft800 kg.m
Maximum righting moment iThe righting moment is a moment (torque) that tends to restore a boat to its previous position after heeling. Its value corresponds to the torque needed to heel the boat for this angle. Higher the righting moment is for an angle, greater is the stability.: 6871 lb.ft950 kg.m @ 50.00 °
