World's 100 Largest Yachts 2007 #66: Aviva
The third same-named yacht for a European owner whose business interests include leading-edge technology should be delivered around the time you're reading this. Her profile deftly blends yachty style with expedition lines, most notably at the knife-like bow. Some of her interior features include a large observation lounge, a conference room, a cinema, two dining rooms, a gym, and a massage and beauty salon. A circular glass elevator (surrounded by the main staircase) connects all six decks and brings daylight down below.

Aviva's owner had some pretty specific objectives in mind before building her. Here, in his own words, is how they developed: "[I] required a combination of speed, efficiency, and passenger comfort at sea that set an altogether new standard....Time was booked at a full-size motion simulator, and some 30 people were pitched, rolled, and wobbled around to definitively establish the characteristics which are found most agreeable by the human body. [I] then worked with the yard to agree on a design that could produce the type of motion that met this ideal....By incorporating a very fine, near vertical "knife" bow, the extra 9 meters (29'5") of waterline length gained not only greatly increases crew accommodation and storage space, it also requires a similar lengthening of the superstructure for visual balance, thus liberating significant extra space throughout...
"As for the performance of the 'knife' bow, which, incidentally, should not be added to an existing hull form but requires sections right through to the stern adjusted to work in harmony with it, the results are dramatic. Despite an overall length only 6 meters (19'7") more than the original Aviva, the new hull achieves a cruising speed that almost matches the previous maximum and at much lower fuel usage. In head seas, the 'knife' bow is a revelation, reducing accelerations forward from approximately 1g of a normal super yacht down to a mere 0.6g. There were initially concerns that such comfort might come at the expense of wetness, but this is not the case, as the bow has more time to rise due to the longer waterline and extra buoyancy forward. Despite pushing the testing tank until water was coming over its sides, the foredeck of the model remained resolutely dry."—Diane M. Byrne
