Verdict

The Lagoon 46 Grand Blue is a well-sorted charter catamaran with strong volume, a practical 4-cabin/4-head layout, and the comfort features expected of a modern cruising platform. It is better suited to relaxed coastal cruising and entertaining than to spirited sailing, but its systems and layout make it a versatile an

Pros

  • +Large beam and open saloon/cockpit layout
  • +4 cabins and 4 bathrooms for charter privacy
  • +Strong cruising amenities: generator, air conditioning, desalinator
  • +Shallow draft supports accessible anchoring and coastal cruising
  • +Good standard nav and dockside equipment for charter use

Cons

  • Sailing performance is moderate rather than lively
  • Twin-hull cruising comfort comes with substantial beam in marinas
  • Charter-focused layout can trade storage for guest volume
  • Listed engine specs vary across public listings

The Lagoon 46 is a full-size cruising catamaran designed around space efficiency and easy living. At 45.9 ft with a 7.96 m beam, it offers the broad platform and open-plan layout that have made the Lagoon line popular in charter fleets and among owners who prioritize livability over performance.

On the water, it should be judged as a capable cruiser rather than a sporty sailing boat. Public references consistently show a shallow draft around 1.3–1.37 m and twin diesel power, which supports confident maneuvering and access to lighter anchorages, but the design is still aimed at stable, forgiving passagemaking rather than high heel-angle excitement.

Comfort is the strong point here. The verified 4-cabin, 4-bathroom arrangement for up to 8 guests gives each couple or family group useful privacy, and the listed equipment set is unusually complete for a charter boat, including air conditioning, generator, desalinator, wifi, and entertainment features. That makes it well suited to warmer cruising grounds and longer stays aboard.

Value is solid if the buyer or charter guest wants a modern, fully equipped catamaran with broad appeal. It is not the cheapest or most performance-oriented option in the class, but the combination of reputable build, generous volume, and charter-friendly systems makes it an easy boat to understand and a practical one to use.
