Yacht description

Built in 2008, nr 5, by King Marine, Buenos Aires. Designed by Mark Mills.
First race June 2008: Commodores Cup,Cowes, Solent

Active racing in The Netherlands, Belgium, UK, Ireland and France untill 2015. 

In 2017 she had a total refit and was transformed in a cruising yacht to sail doublehanded. Since 2017  sailing in the Med. On the moment lying in Marina St Elmo, Cagliari, Sardinia.


The KING 40 is a true dual-purpose cruiser/racer which can compete successfully offshore or around the cans, yet still offers a comfortable cockpit and interior for relaxed family sailing. The KING 40 builds on the two most successful designs of this size in recent years, the IRC 39 Mariners Cove and the IRC 40 Tiamat: both UK IRC Champions in 2006. With winning in its genes, the KING 40 has been positioned to ensure that it has the widest possible performance band, with particular focus on light and medium airs racing. High stability is encouraged by the IRC rule and ensures pace all the way up the wind range. The KING 40 easily surpasses existing stability requirements for the world’s great ocean races.

This is a turn-key IRC race boat that allows the new owner to immediately get out there and be at the top of the leaderboard.

This Mills design still is one of the most competitive IRC boats in this size bracket

The King 40 is built in accordance with the European CE-certification and meets the CE-Directive 94/25/CE Category A “Ocean” for recreational vessels.
