Interior
The boat is equipped with a galley and toilet facility.

Keel

The Finncraft 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 keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.


Engine

The boat is typically equipped with an inboard BMW D 35 engine at 35.0 hp (26 kW).

The fuel tank has a capacity of 120.0 liters (31 US gallons, 26 imperial gallons).
