Cost: around $2,000,000

Lagoon catamarans started out in 1984 and are now part of Groupe Beneteau, the luxury French yacht maker. The uber marine architects Marc Van Peteghem and Vincent Lauriot Prevost (VPLP) are the designers for the Lagoon range and it’s the design elements that really set this boat apart from the rest.

The vertical salon windows and ‘eyebrow’ roof overhang give the whole Lagoon range a very distinctive look (somewhat similar to the Fountaine Pajot windows). If you are not familiar with this look you may initially prefer the raked windows of other cats, but the Lagoon design is all about function, maximizing internal space and keeping the sun out of the salon. Most people end up loving this design although it is a rather ernest and somewhat boxy look.

The 620 is the top of the standard Lagoon range (they also do custom builds) and at 18.90 metres (62 feet) this is one huge yacht.

The list of features is too numerous to mention here, suffice to say there is a huge rear deck (cockpit), massive internal living area (salon) that is more like a luxury apartment than a yacht, a sensational fit out, incredible sleeping cabins and all the marine navigation equipment you could wish for.

For the ultimate ocean-going catamaran that will take a big family anywhere in the world in total luxury, it’s impossible to go past the Lagoon 620.
