About the LAGOON SEVENTY 7
Hull length: 23.28m / 76.42 ft Exterior design: Patrick Le Quément Interior design: Nauta Design Also available with John Deere N5-230hp engine
The Lagoon Seventy 7 is a large performance catamaran designed by VPLP Design and built by Lagoon, with production starting in 2017. As a flagship model, it represents the upper echelon of the builder's range, though exact total hull counts remain unspecified in available data.
- Best for:
- This vessel is ideal for experienced multihandlers seeking high-performance coastal cruising and short offshore passages, prioritizing speed and spacious living areas over heavy bluewater isolation.
- Bluewater capability:
- With a displacement of 139658.0 lb and a capsize ratio of 2.79, the boat offers reasonable stability for coastal work, but its light comfort ratio of 23.86 and high sail area indicate it is tuned for performance rather than heavy offshore comfort.
- Comparables:
- Comparable vessels include the Fountaine-Pajot Astrea 42 and Lagoon 42, as they share similar performance-oriented hull forms and target the same market of active cruisers seeking modern amenities and speed.
