Rig

The Ohlson 29 is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

Keel

Fin keel

The Ohlson 29 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 most marinas as the draft is just about 1.58 - 1.68 meter (5.18 - 5.48 ft) dependent on the load.

Engine

The boat may be equipped with an inboard Volvo Penta MD6A diesel engine at 10 hp (7 kW).
