The headroom is above average
The Sun Odyssey 479 has been built with more than one type of keel.
One option is 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.
Another option is a L keel. The keel is an L-shape and therefore less exposed to seaweed, fishing nets and lines.
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.
The boat can only enter major marinas as the draft is about 2.44 - 2.54 meter (8.01 - 8.31 ft) dependent on the load.
