About
Step aboard “Monaco Blue,” a beautifully equipped and extensively upgraded Lagoon 450 F that is truly ready for her next adventure. Widely regarded as one of the most successful cruising catamarans ever built, the Lagoon 450 F earned its reputation through an exceptional combination of comfort, performance, and livability, with more than 850 hulls produced during its celebrated production run.
Designed for effortless long-range cruising, the 450 F offers an open, light-filled interior with excellent ventilation, spacious accommodations, and one of the most functional layouts in her class. The expansive aft cockpit flows seamlessly into the saloon, creating an inviting social space for entertaining or relaxing at anchor, while wide side decks and secure access forward make moving around the boat safe and easy underway. Up top, the flybridge helm delivers outstanding visibility and a comfortable command position in all conditions.
“Monaco Blue” is a proven bluewater cruiser with an impressive cruising pedigree. Originally based in the Mediterranean, she successfully crossed the Atlantic and has spent recent years exploring the Caribbean. She has clearly benefited from attentive ownership and thoughtful upgrades throughout her life, and she presents as a vessel prepared for immediate cruising.
Notable equipment and upgrades include:
Configured in the desirable owner/family layout, “Monaco Blue” offers exceptional storage capacity and flexible accommodations ideal for extended cruising, liveaboard life, or hosting family and guests comfortably aboard.
For buyers seeking a properly equipped, well-maintained cruising catamaran with proven offshore capability, “Monaco Blue” represents an outstanding opportunity. The best-surveying cruising cats are often the ones actively used and continuously cared for by knowledgeable owners—and this vessel is an excellent example of exactly that.

Great Service, Great People
Helped me through the process.
I would go through them again in a future purchase.
The Multihull Company made the process of buying our boat easy and predictable. Both our agent (Francisco Montaner) and Andrew Holland communicated well and educated/informed us of each step in the process. I highly recommend The Multihull Company for those shopping for a catamaran!
Chuck at The Multihull Company is the real deal.
He helped us find our Lagoon 40 after genuinely listening to what we needed, not just what he had to sell. He let us visit the boat multiple times, answered every question honestly, and helped us make a confident decision on a major purchase.
What impressed us most was the post-sale support. Once the paperwork was signed, Chuck was still picking up the phone, offering referrals, and helping us work through the early stages of liveaboard life. That kind of follow-through is rare.
If you are looking for a multihull and want someone who knows the boats and actually cares about the outcome, Chuck is the person to call.
We just purchased a 2025 Nautitech 44 Open with The Multihull Company. The process of getting here has been great, and we could not have asked for a better agent. We worked with Conor, whom we met at the 2025 Cannes Boat Show. We started our search for a cruising catamaran in Florida at the beginning of the year. We spent a couple of months looking at different boats/models within our price range and quickly narrowed it down to what really mattered to us, in part thanks to the wealth of knowledge and expertise our broker provided. When we found a perfect match in Montenegro, Conor and The Multihull Company did not hesitate to continue supporting us and to lead the efforts from start to finish with great care and transparency. Communication and support have been outstanding throughout this entire process. Conor, in particular, showed great compassion and care, going above and beyond to ensure that no stone was left unturned and that we would be able to safely and happily sail off into our big adventure.
A sale well handled. No inflated expectations and an honest opinion throughout. Highly recommended.
Successful relationships cannot exist without it. At The Multihull Company we base every relationship on a firm commitment to earning and retaining our client’s trust.
Advice of any kind is valuable only when grounded in hard-won expertise. It too, must be trustworthy. Trust and expertise define the heart and soul of The Multihull Company.
