Bold explorer yacht: 85.3 m SilverYachts, aluminium hull, helideck and hangar, 5,500 nm at 12 kn

In short

Bold takes a different route to expedition capability from the steel, ice-classed explorers: an 85.3-metre aluminium hull with a 2.7-metre draught, a top speed of 23 knots and no ice notation in her Lloyd's Register class (SilverYachts). Her owner and Espen Øino built her as a “sports activity vessel” around a 400 m² open main deck that can take a helicopter, a 15-metre tender or loads of up to 12 tonnes, with a certified helideck and a hangar (Boat International, SilverYachts). The shipyard gives 5,500 nautical miles at 12 knots and 60 days of autonomy (SilverYachts). Her broker reports a five-year circumnavigation of more than 120,000 nautical miles, from the South Pacific to the Mediterranean (Ocean Independence).
