2007 Lagoon 420

SummaryLagoon 420 | Extensively Modified Performance-Oriented Cruising CatamaranRollercoaster 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 420but want significantly improved offshore performance, motion, and safetythis 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 forwhile 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.Hull & Structural ModificationsExtended Transoms Approx. 5 ft (1.5 m)Eliminates submerged transoms for reduced dragSubstantially increases reserve buoyancy aftGreatly reduces hobby-horsing in short-period seasImproves boarding, swimming access, and deck spaceFinished with Plasdeck Cool Teak (cooler underfoot, no maintenance)Extended Axe Bows Approx. 3 ft (1 m)Narrower, wave-piercing entry inspired by modern axe-bow researchImproves comfort and safety when motoring or sailing into head seasEnhances overall seaworthiness and offshore capabilityNet EffectApproximately 49 ft effective waterline lengthImproved passage speedsMore controlled motion in inlets and offshore conditionsRig & Sail InventoryFull-batten, large-roach mainsail (stock)Furling headsail (stock)Quantum A3 Asymmetric Spinnaker (~1,200 sq ft)Ground Tackle & Deck Hardware60 lb Ultra Anchor with flip swivelFortress FX-85 secondary anchor200 ft of 3/8″ chain (2020)Lofrans Project 1000 windlassCustom heavy-duty davitsDual swing-arm lifting davits (~300 lb each)Integrated into solar archCockpit & ExteriorFull cockpit enclosureCockpit dodgerAft roll-up cockpit shadesStandard Lagoon cockpit cushionsExterior sun screen curtainsAft bench seatingKayak / SUP carrierElectrical & Energy SystemsThis vessel is designed for true off-grid cruising with a highly efficient 24-volt lithium system.House Battery Bank4 ReLion 10.2 kWh RB24V100 LiFePO batteries (2019)Total capacity: 12.8 kWh @ 24 voltsSolar6 Kyocera 250-watt marine solar panels (1,500 watts total)Panels integrated into davits and bimini for shade and efficiency2 Outback 60A MPPT solar charge controllersInverter / ChargingOutback 3500-watt inverter/chargerSeparate 120V / 20A circuit for high-draw galley appliancesOutback MATE network monitoring systemStarting & Legacy Systems3 Napa 775 starting batteriesOriginal 12V system retained for lighting, windlass, winches, electronicsVictron step-down converters supply 24V 12V efficientlyGeneratorOnan 21.5 kW generator (approx. 4,730 hours)Plumbing & UtilitiesSpectra Catalina 300 watermakerQuick electric water heaterPanda portable washerElectric hot water capability via solar under favorable conditionsGalley & InteriorIsotherm CR130 refrigeratorIsotherm CR90F freezerDual-burner induction cooktopSunbeam microwaveEdgestar icemakerLagoon blue upholsteryLagoon standard curtainsAccommodations & Climate Control3-cabin / 3-head owners version layoutManual Jabsco heads4-zone air conditioning:(3) 8,000 BTU units(1) 24,000 BTU unitNavigation & ElectronicsRaymarine HD color radar (2017)Raymarine Axiom 12 chartplotter (2020)Raymarine SmartPilot autopilot (hydraulic)Raymarine AIS Class B transceiverPlastimo compassBahamas Explorer chartsMaptech charts for U.S. East Coast & Puerto Rico(2) Handheld VHF radiosHelm steering wheel lock tied to autopilot hydraulic valvePropulsion & MechanicalTwin Yanmar diesels with SD-50 saildrivesSaildrive thrust bearings upgraded to non-wearing needle bearings (2017)Gori 2-blade folding propellersExcellent sailing efficiencyReduced dragLine-shedding designStanding rigging replaced with Staylock / Norseman fittings (2017)Safety & TenderACR Global EPIRBWalker Bay console tender w/30 HP Tahatsu outboardDisclaimerThe Company offers the details of this vessel in good faith but cannot guarantee or warrant the accuracy of this information nor warrant the condition of the vessel.
