Keel

The Dehler 34 Nova Top is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

The boat can enter even shallow marinas as the draft is just about 1.45 - 1.55 meter (4.76 - 5.06 ft) dependent on the load. See immersion rate below.


Engine

Dehler 34 Nova Top is typically equipped with an inboard Yanmar 3GM30F diesel engine at 27.0 hp (20 kW).

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.
