Introduced at the Annapolis Boat show in October 2006 (model year 2007) the LAGOON 420 was advertised as 'the first series-produced sailboat with diesel-electric drives as standard equipment'.
A number of layouts available with owner or charter versions.
Offered for sale/charter from the Moorings company.
An updated version is the LAGOON 421, equipped with the more conventional twin diesel power.
Replaced with a new (2015) LAGOON 42. (listed here as LAGOON 42-2).
