The SL78 is the entry-level model in the SL range, Sanlorenzo‘s fleet of fiberglass, planing-hull motor-yachts. Sanlorenzo has channeled its decades of experience into both the new SL78 and the next in line, the SL86, combining signature styling with new innovations and an unparalleled level of customisation within its category.

Key Features

Like her bigger sister, the SL 86, the new SL78 features now bigger windows on the main deck, so the main saloon is bathed in natural light, making the entire space seem even bigger than it already is.

The layout is offered in two options: one places the galley on the main deck, the other sees the galley on the lower deck, adjacent to the crew quarters, which allows for an even larger entertaining and guest area on the main deck and also keeps the main deck private for the owner’s living space entirely.

An interior floating staircase, a beautiful design feature, leads up to the flybridge, which is covered by a smartly operated hardtop for ample shade and also has plentiful space where guests can enjoy the views. Or perch at the huge shaded lounge area on the bow and take in the views ahead.

The yacht was awarded with Best Exterior Award in 80-120 feet category at the 2016 World Yacht Trophies held in Cannes during the yacht show with several SL78s already cruising around Hong Kong.

  • Internal “floating staircase” to flybridge, a piece of art on its own
  • Large tender garage that can house a 3.85 metre Williams jet tender
