This volume includes a selection of truly groundbreaking yachts and noteworthy design developments. Tom Perkins' three-masted schooner Maltese Falcon is perhaps the best example of how owner-driven demand can result in a quite extraordinary vessel – in this case probably the most significant development of a sailing yacht's propulsion system since the introduction of the Bermudan Rig. In other yachts illustrated in this volume you will see how access to the sea for the owner and his guests is being improved by the creation of 'beach club' sterns, where the traditional working lazarette is replaced by a waterside relaxation area. Such an area is also seen in the CRN-built Ability, which picks up the latest trend for terraces by having a private balcony built into the master suite. Mirgab V, too, has a side-terrace that opens from the main saloon, uniting it with the outside world and providing the ability to place a deckchair on an otherwise too-narrow side deck. Sun deck design is also evolving. Hard-top biminis seem to be replacing canvas and wire structures. Sailing yachts, too, feature new layouts – with the Wally-built Esense, Pink Gin from Baltic Yachts andMystere designed by Bill Tripp all showing new thinking in this respect.
