The boat is equipped with 9 berths.
The Mason 43 has been built with different keel alternatives.
Unknown keel type
The boat can only enter major marinas as the draft is about 1.85 - 1.95 meter (6.07 - 6.37 ft) dependent on the load. See immersion rate below.
Full keel
The Mason 43 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.
Mason 43 can only enter major marinas as the draft is about 1.91 - 2.01 meter (6.27 - 6.57 ft) dependent on the load. See immersion rate below.
