Extended Transoms for a Better Circulation

Step effortlessly aboard the Lagoon 51 thanks to the large and wide transoms. This feature provides safe and practical access to the dockside.

In association with the Tenderlift, this represents a super large balcony by the sea. At mooring, this large bathing platform is an invitation to swim and relax with your feet in the water!

For easy circulation on board, there are only 2 very small steps between the cockpit and the transoms. The level between the two is considerably low, making it the most accomplished solution on the market. Practical and design, it meets a real need.

Welcoming Forward Cockpit 

Walk along the side-decks to reach the forward cockpit.

This beautiful space has an unobstructed view over the ocean and is designed to meet your every need: whether sharing sundowners or laying back comfortably in the middle of the day under the shade sail.

Forward cockpit hosts nice amenities like plenty of cupholders, a nice coffee table, and sun protection to enjoy every moment.

New Generation Interior

Step into a spacious salon- Discover the innovative concepts of space. Thanks to the mast being stepped on the fore-end of the saloon, the view is continuous. The great luminosity, coming from the 360° vertical windows, and the new wood finishes “Alpi sand oak” simply reinforces this feeling of space.

Wherever you are, the volume of this salon is impressive, allowing for easy circulation. In addition, it offers all the practical solutions you would expect on a Lagoon.

Always more comfort for the owners-The owner’s cabin benefits as well from this layout optimization and proposes, as standard, a large walk-in dressing.
