The hull is made of wood.
Full keel
The Nyyc 40 is equipped with a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.
The boat can only enter major marinas as the draft is about 2.62 - 2.72 meter (8.60 - 8.90 ft) dependent on the load. See immersion rate below.
