Nautilus Yacht Management is proud to present this beautifully presented Lagoon 450F. With an extensive upgrade carried out just these past couple of years, this yacht truly stands out if you are looking for a catamaran that is ready for you to begin your journey right away. Home to a family from Canada who has owned this yacht since new, she has carried them safely from the Caribbean to NZ and Fiji for the past one and half year. As most cruisers carry out upgrades before they begin their journey and usually sell after many years, SV is a wonderful opportunity to purchase a Lagoon 450F that has had all its upgrades done very recently, and which were all tested as well. A true gem and a rare find on the market.

The Lagoon 450 is one of the most popular mid-size cruising catamarans in the world. It is highly favoured for family circumnavigation due to its unmatched space, stability, and safety, acting as a true "floating home" designed to handle extended Bluewater passages.

Why Families Love the Lagoon 450
Exceptional Stability & Safety: Lagoon catamarans are designed to minimise the risk of seasickness and provide a safer, more secure environment for children to walk, play, and move around while underway.
Abundant Living Space: It features 4 spacious cabins with their own private ensuites, and a roomy, light-filled saloon. The wide wrap-around windows allow the family to enjoy 360-degree views, making indoor days comfortable for cooking, eating, and schooling.
Multiple Social Zones: The boat is built with separated relaxation areas, allowing the family to spread out. The enclosed aft cockpit is perfect for alfresco dining, while the forward trampoline and upper deck seating provide great areas for wildlife viewing or relaxing at anchor.
Self-Sufficiency & Storage: Designed for long-distance cruising, it boasts high capacities for fuel, fresh water, and refrigeration, enabling families to live independently for extended periods.
Reliable Handling: Over 1,000 hulls have been produced, making it a tried-and-tested Bluewater multihull. It provides excellent volume while remaining manageable for a cruising couple or family to sail.

A Word from the Owners

"Wonder has been the ultimate cruising boat for our family. We have loved the overall layout and the many benefits of the Lagoon 450F.

She sails beautifully - we're often the faster boat even though we're quite heavy, and we've got huge fuel tanks that really offer a lot of peace of mind on long passages. There's great visibility from the fly bridge compared to most catamarans, making it much easier to go through areas with coral bommies, dock, raft up, or catch mooring balls.

There are a lot of seating areas (bow, flybridge, cockpit, salon) we can hang out at to either have quiet time or host friends. We're often a boat that hosts as we've got more space than many (but don't worry, cruisers always bring snacks and drinks!). We've also enjoyed having a lot of extended visits by family and friends - the spare room has been wonderful for both that as well as storage when it's just the four of us.

This boat is very well ventilated. While the air conditioning works perfectly, we find we almost never want to use it as the hatches are designed to create great airflow throughout.

And the modifications we've made since we have been moved aboard have been outstanding. Between the batteries and the solar, we usually have plenty of power, rarely running the generator for most of the year, even though we are a 'power hungry boat' with lots of amenities. And those amenities can be either 220V or 110V. The bigger anchor and lots of chain always holds fast. The larger watermaker has never failed. The ample storage space and our various storage additions (tie downs for tool bins in the engine lockers, spice rack, hammocks, etc. ) have meant that we can have most of the amenities from land that we are used to.

We put Wonder in charter for her first 7 years, but I think the difference has been that we, the original owners, 'helped' the charter company the entire time to stay on top of repairs and maintenance, keeping the boat in top shape and not accepting substandard fixes. There wasn't really anything wrong with Wonder when we moved aboard apart from a bit of wear and tear. And any lingering issues have long been worked out as the mechanical engineer onboard has maintained all parts of Wonder meticulously.

Our family of four has cruised on Wonder full time for 1.5 years. We sadly need to get back to land life after our adventures. One of the hardest parts will be to leave this home, which has kept us feeling safe and brought us to explore so many new places, from the Caribbean to Fiji. We sincerely hope she continues on to do the same for her next owners. "
