2025 Lagoon SEVENTY 8

The Lagoon SEVENTY 8 is a 78-foot fiberglass catamaran designed around generous living space and privacy. Twin diesel engines producing 1,020 horsepower support extended cruising with the range and stability that the catamaran platform delivers. The broad 36-foot beam maximizes interior volume and on-deck comfort, creating distinct areas for relaxation, dining, and socializing across the bridgedeck and hulls.

The layout emphasizes a cruising lifestyle with room for the activities that make extended time aboard rewarding—swimming from the platform, reading, and gathering in comfortable social spaces. The catamaran's shallow draft and twin-hull design provide the stability and seakindliness needed for confident passage-making while maintaining the ease of handling that appeals to owner-operators and small crews.
