Interior

The interior of the 3-cabin owner's version Lagoon 42 is bright, spacious, and highly livable. 

The salon features a comfortable U-shaped settee with a dining table to port and a forward-facing navigation station to starboard. Sliding glass doors connect seamlessly to the aft cockpit, effectively creating one large indoor/outdoor space. The galley is positioned aft for easy access to both the salon and cockpit, and is well-equipped with ample counter space, refrigeration, and storage for extended cruising.

The port hull is dedicated entirely to the owner's suite, offering a full-beam layout with an island berth, desk/vanity area, generous storage, and a large private head with a separate shower. The starboard hull includes two comfortable guest cabins, each with double berths, good natural light, and storage, and two heads with showers.

Thoughtful details like wide companionways, good ventilation, and clean, modern finishes make the Lagoon 42's interior especially comfortable for liveaboard use or extended passagemaking.
