Interior

The boat is equipped with 6 berths.


Keel

Fin keel

The Jongert 20s 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 keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can only enter major marinas as the draft is about 3.00 - 3.10 meter (9.84 - 10.14 ft) dependent on the load. See immersion rate below.


Engine

Jongert 20s may be equipped with an inboard Mercedes-Benz diesel engine
