"Serenity Cat" is a highly desirable, exceptionally well-maintained 3-cabin Owners Version of the popular Lagoon 420.

My Opinion

New Rigging (Feb 2024) and New Ground Tackle (2025): Standing rigging replacement is an expensive, mandatory insurance requirement every 10 years in Australia, making this a major cost-saving bonus for buyers. The inclusion of a top-tier Excel anchor paired with a brand-new Quick windlass provides immediate safety and anchoring reliability. Massive 2200W Solar / 980Ah Lithium System: This is a top-spec power upgrade that completely modernises the vessel's electrical capacity. It allows the future owner to run the 240V air fryers, watermaker, and lifestyle electronics directly off the sun without constantly idling the generator.

The Australian catamaran market remains highly resilient for well-priced, turnkey "Owners Version" hulls because buyers heavily favour avoiding the shipyard wait times and high costs associated with refitting an older boat. Dropping the price to $450,000 puts this vessel at a very competitive entry point for a Lagoon of this size class. A buyer seeking an immediate Queensland liveaboard will snap it up within 30 days for close to the asking price, recognising that the new rigging, lithium package, and Excel anchor save them at least $40,000 in immediate refit costs. Worst Case Scenario: The combination of the desirable Owners Version layout, clear "ready to cruise" status, and a fresh $450k starting benchmark will appeal strongly to a cruising couple who wants to avoid a project boat and wants to get moving north before the season shifts. My Opinion: The $450,000 list price is perfectly positioned to stimulate immediate traction. The 2024 rigging and massive lithium/solar infrastructure hold genuine market value that will separate this hull from cheaper, poorly maintained alternatives on the market.
