Lagoon 420 | Extensively Modified Performance-Oriented Cruising Catamaran
Rollercoaster is a highly customized Lagoon 420 that stands apart from any standard example on the market. Designed for owners who value the legendary comfort, layout, and livability of the Lagoon 420-but want significantly improved offshore performance, motion, and safety-this vessel has undergone a professionally engineered hull transformation and comprehensive systems upgrades.
Following extensive research and consultation with experienced fabricators and naval design principles, Rollercoaster was lengthened both aft and forward, resulting in a dramatically increased waterline length, reduced pitching, improved speed, and a noticeably smoother motion in a seaway. All structural modifications were executed by Cracker Boy Boatworks (Riviera Beach, FL) and inspected during construction by a marine surveyor (survey documentation available upon request).
The result is a rare opportunity: a proven, comfortable cruising catamaran with the waterline length, reserve buoyancy, and wave-piercing characteristics typically found on much larger performance cats.
Rollercoaster is not a typical Lagoon 420. It is a thoughtfully re-engineered cruising catamaran that retains the exceptional interior volume, cockpit-galley flow, and liveaboard comfort the model is known for-while delivering the speed, motion control, and offshore confidence of a much longer vessel.
For sailors seeking a proven, long-range cruising platform with meaningful structural upgrades, serious energy independence, and professional execution throughout, Rollercoaster represents a rare and compelling opportunity.
