Lagoon 420 - Duo


Duo is a very well presented Lagoon 420 now exclusively for sale with the team at YOTI on the Gold Coast.

The innovative Lagoon 420 combines great liveaboard accommodation with modern sailing and power systems. Duo was initially earmarked when built in 2007 to be fitted with electric motors as part of the initial Hybrid version of these vessels. The vessel remained at the yard, uncompleted, as Lagoon evaluated the Hybrid choice. Duo was only launched in 2009 after having installed two 75HP Yanmar diesel engines (2009).

The Lagoon 420 has the trademark vertical windows that create tremendous saloon volume with headroom all around and great undistorted views. "Eyebrows" limit the solar heat that enters the accommodation and additional permanent shades have been installed to enhance that for the tropics.

The saloon has an L shaped well-appointed galley, with which is within an arm reach of the cockpit. Besides the forward-facing navigation station, there is an L shaped Settee and bench to seat 8 people around interchangeable tables.

Duo is the 3-bedroom owners' version. The port hull is dedicated to the owners, with a large luxury bathroom and outstanding living areas. The starboard hull incorporates two double cabins, both with an Ensuite. All cabins feature Lagoon's large hull windows, which flood the accommodation with light and allow great views of the sea.

Her spacious cockpit can seat 8 around the dining or coffee table, with great access to the saloon through the large sliding door and window. The helm is raised to starboard, which allows good all-round visibility, whilst still in full contact with the cockpit and close to the saloon. A much-preferred layout by cruising couples and families. Furthermore, all sailing control lines come back to the electric winches and line stoppers, positioned next to the helm.

The deckhouse provides solid handholds for getting around the vessel, with the flat decks with recessed hatches offer firm footing.
The exterior storage on this vessel is huge with two full-height bow lockers, three forward deck lockers and two large lockers just forward of the deckhouse. Cockpit cushions transform this foredeck in another social area.

This vessel is equipped for world cruising with everything needed to cruise in comfort and safety: full Raymarine instrumentation with plotter screens at helm and nav station, including radar, AIS receiver and Iridium Sat phone. 800W solar panel is installed on the solid bimini top and a 17.5Kw Onan Genset provides ample power for air conditioning, the 100l/h Watermaker and a washing machine.

Duo has just been antifouled incl propspeed, and polished at the Boatworks, Gold Coast Marine Precinct,
