Price: AUD $625,000

Diamond B is a beautifully presented 2013 Lagoon 421 that is now listed exclusively for sale with the team at YOTI in Sydney.

Significantly upgraded by her current owner since their purchase in 2020, Diamond B is now a very capable, safe, and self-sufficient Bluewater cruising catamaran. Her upgrades were designed to allow her owners to monitor and control her onboard systems remotely and achieve absolute 'off the grid' cruising capability.

Some of these improvements include the addition of a 4 x 200 a/h Victron Lithium house battery array, with Lynx Smart BMS, powered by 3 x 270W Solar Panels on an adjustable Stainless-Steel frame plus 4 x 185 SunMan eArc Solar Panel on her cabin top all controlled by 2 x Victron 150/85 MPPT smart solar controllers. In the past two years, she has also been fitted with a new inventory of Raymarine sailing instruments, which include 2 x Axiom 2 Pro plotters, 2 x i70 multifunction displays and only this year, a new Raymarine Evolution - EV1 course computer with P70s autopilot at her helm.

A 9.5Kw Onan genset helps run her full Cruisair air conditioning system, and a 120l/h Watermaker allows this Lagoon to be extremely self-sufficient. All her standing rigging was replaced in November 2023, and just for good measure, her running rigging was also replaced in June 2024.

She is powered by 2 x Yanmar 40hp diesels that were serviced in November 2024, and at the same time, she was antifouled and polished.

As the three-cabin owner version, the port hull is dedicated to the owners, with large heads and a standing shower in the bow, outstanding living areas and a huge master suite aft with a large island double berth. The starboard hull features two double cabins, both with an ensuite. Her spacious cockpit can seat eight around the dining table, and the large sliding door and window provide excellent access into the saloon. The helm is raised to starboard, which allows good all-round visibility while still being in full contact with the cockpit and close to the saloon.

Diamond B is located in Sydney Harbour and worth inspection. She is a beautifully presented and exceptionally well-specified Lagoon 421, now listed with YOTI. Don't hesitate to contact Tim Vine to discuss Diamond B further.
