This Lagoon 450 F, owner’s version, presents the elaborate chic typical of Lagoon Catamarans. Spanning 13.96m in length the 450 F is an obvious progression from the preceding 440 model, which itself was a fantastic piece of craftsmanship. The 450, however, is a worthy successor, leaving little to nothing to be desired. 

 L'Obsession is aptly named and a beautifully presented example of one of the most popular Lagoon Catamaran ever built. She is the only Lagoon 450 for sale in the Southern Hemisphere and one of the only ones in the world that is both owner's version and which has never been chartered, being a cherished member of the same family since they placed their order directly with Lagoon France in 2010.

Her owners, a family from California, took delivery in 2011 to enjoy around the San Fransisco bays, (she provided an ideal base to watch the 2013 America's Cup) and eventually sailed her across the Pacific to French Polynesia, Tonga and Fiji, which then became L’Obsession’s idyllic base these past 5 years between trips to Vanuatu and New Caledonia.

Safely tucked into a cyclone-proof marina when in summer storage, her owners returning each year for the 6 months sailing season to enjoy Fiji's world renowned surf spots and to  the South Pacific.

Regularly updated and lovingly maintained, this Lagoon 450 F is simply stunning. Our team has crawled all over her and inspected her in every details, improving where needed in consultation with the owner. A few very small list of cosmetic imperfections are listed in more details below, but the yacht is in remarkably good order and was independently assessed by an accredited marine surveyor.

Available at a very attractive price due to the owner's current circumstances this beautiful yacht should make her new owners very happy indeed. She is fully set up and ready to continue sailing anywhere in the world.

Rarely available on the market as a one-owner, owner’s version and never chartered option, the Lagoon 450 F l’Obsession is sure to be highly noticeable to anyone looking for high quality pre-owned multihull at the price of an ex-charter vessel. She has also been further improved with full standing rigging replacement 2 years ago, a recently updated comprehensive suite of electronics and comes equipped with everything you need to move on board today without further expenses necessary. 

L’Obsession was fully surveyed in February 2020 by an independent Australian surveyor specialising in multihulls just before travel restrictions were imposed in Fiji. She was slipped, antifouled and polished in late February.

Everything on board has been further tested by our representative in Fiji, who will continue to supervise her caretaking and maintenance until sold. Please contact us at any time if you wish to organise a video walk-through at your convenience via Zoom or Whatsapp.

Improving on the immensely successful Lagoon 440 was not an easy task, and Lagoon put a lot of thought into perfecting what was already a winning formula. 

With regards to their unbeatable status as roomy, robust and elegant cruising catamarans favoured by families all around the world as the perfect choice for their adventures on the high seas,  Lagoon paid close attention to Lagoon owners suggestions and revisited the LG440 with a view to keep what made the design so popular, while at the same time improving on the areas that were especially important to live-aboard families and with additional focus on safety at sea.

To begin with the ‘serious’ end of the boat, a significant transformation from the LG440 is the flybridge and it’s accessibility. The flybridge, around which the entire deck layout is centred (the “F” in “450 F” actually stands for “flybridge”) has been redesigned.

A major improvement is that you can now quite easily access the bridge, with its steering station, navigation equipment, engine controls, sheets, etc., giving you full control of the boat at your fingertips, while staying close to your family and guests with a long, convivial lounge and direct access to the giant sunbathing lounge just before you on the upper deck. The flybridge is accessed by a set of stairs on either side incorporated directly into the cockpit to port and starboard. Not only this is a better use of space, but it is also a much better approach from a safety standpoint. 

The cockpit itself has been reorganized, with a new wrap-around settee and dining to port and an inviting lounge or daybed to starboard that significantly opens up the floor plan. There is also an overhead opening hatch in the hard dodger that can offer ventilation and sunshine in good weather, and protection from the elements under harsh conditions. This hatch also gives view of the port side aft corner to help when docking short-handed. There are abundant locker spaces, including a huge space below the double which currently holds an entire workshop of tools and spare parts, opposite a large cabinet housing more storage and a 100L fridge / freezer perfect for cooling drinks and keeping you well supplied with ice. 

Designed to be the second most used living space on board and virtually where you are likely to spend most of your time relaxing at anchor or while under way, the cockpit seamlessly opens onto the interior. The coffee table can be swapped for the large diner table currently inside the salon, whichever set-up suits you best. A dedicated storage space hidden into the cockpit hardtop is designed to store a additional full size table should you wish to have two full size tales on board as well as somewhere to stow whichever one is not in use. 

Frontward of the distinctive cabin house, sporting the typical Lagoon rounded corners and big windows, there is a second cockpit/lounge area with a pair of colossal seat lockers. The whole forward section of the boat  can be kept shaded by a brand new shade cloth specifically designed and installed by local sail makers out of durable and lightweight material.

Forward again are two very large lockers designed to keep your water toys and spare sails out of the way. They are independently accessed via a deck hatch and sealed off the rest of the boat.


Flawing seamlessly from the outdoor to the indoor area, L’Obsession is designed around a wonderfully bright and inviting salon with a markedly wider traffic areas when compared to the Lagoon 440. If in theory the two models, LG440 and LG450 are only one foot apart, the usable space found on both models is noticeably more generous on the larger vessel. As well as a roomier interior, the added storage space is also significant. The boat is clearly designed for life on board and for those who enjoy exploring the world’s far reaches in absolute comfort.

The salon is large enough to comfortably accommodate 6 /8  people. The lovely Sunbrella washable suede fabric was recently replaced and presents in great condition. Opposite is the tastefully hidden flat screen TV, which is installed on an electric lift system.

To the left of the salon, L’Obsession has been fitted with the enviable inside control station, compete with electronic engine controls, access to all your instruments and navigation equipment, and from where you can control the entire ship at your fingertips just as easily as you would from the bridge. (Please note that the engine controls have been recently replaced and needs syncing. Our technician has not yet been able to get them to work but we will keep trying).

The galley is U shape and equipped with everything needed for gourmet dinners. The stove / oven / broiler is brand new. There is a triple stainless sink and three taps, one hot and cold fresh water mixer with extendable shower-type faucet, a second tap is connected to a salt-water pump and the third one feeding directly to the Spectra Newport water-maker, perfect for those who want the freshest water going straight from the desalination system to their drink bottle. 

To the right is are the four steps down to the owner’s stateroom, which is a veritable apartment in itself and which can be enclosed for privacy behind a sliding companionway door. The spacious double bed is at a great height to provide a great view over the ocean out of the large picture window. Each bed on L’Obsession is fitted with good quality mattresses in washable covers raised over customised slats for air flow.

Forward is a good size settee, home office and multiple storage lockers.

The master’s head area could rival what you would expect in an stylish apartment. 

L’Obsession was deliberately equipped by her owners with 3 manual toilets as opposed to electric because of their silent operation and durability. Each is attached to a holding tank for use when in protected areas.

The port side is designed as two stateroom, each with it’s own door. Both are pleasant, bright and well ventilated little apartments with their own generously sized ensuite head with separate shower.

The forward facing overhead hatches provide air flow that is easy to regulate and which will keep you cool at night. Thanks to Lagoon's great design with regards to air flow, L'Obsession's owners never felt the need to add air conditioning in spite of their 5 years in the tropics. These same hatches are fitted with a retractable blind and mosquito net which slides away when not needed.

Something that is striking on L’Obsession is her stunning presentation and lack of wear and tear, even in traffic areas. The timber fit-out is in great condition, there is no mildew or smell and every surface presents almost new. The teak copckpit and bathroom floors are in beautiful condition and were gently brightened by our team just last week without the use of chemicals. 

The only blemished we could find on this beautiful boat is water damage to the cockpit coffee table, which needs to be re-varnished. (The protective cover for that table had trapped water, which over time this summer degraded the varnish.) There are some rust spots in the two fridges, and the Perspex of a small overhead bathroom hatch on the portside is cracked, although it does not leak. The mainsail and Genoa are serviceable but original, so may need replacing in a couple of years. Lastly, the outdoor upholstery is original and could do with being replaced, although it is not holed or damaged other than showing a few stains and discoloration here and there.

Our team is currently attending to some last-minute detailing, such as removing a few rust stains on the deck, polishing the stainless-steel fittings etc. L’Obsession’s owners are now back home in the US but we will continue to care for this beautiful yacht until she has found a new home.
