Ubi is a 43’ blue water aluminum centreboard in very good condition with 3 cabins, sleeping 6 comfortably. Rated for a crew of 8 for ocean sailing, 10 for offshore, and 12 people for coastal sailing.

Ovni yachts, built by Alubat in France, are perhaps one of the most widely known and internationally recognized cruising yachts in the world. There are few yachts as admired and displaying as many qualities in each of their models as an Ovni.

From France to Australia, the USA or South Africa, almost anyone, even without much knowledge of yacht builders, will know Ovni, and for those who don't, one look at them is enough to plainly see that this is a yacht far above the rest. These boats have been designed with the ocean in mind, and intended for long distance cruising. All the Ovni owners we have met in 10 years of working with cruising sailors have said that if they ever purchased another boat, it would have to be an Ovni again.

Their first attribute is their strength. As Alubat's moto clearly demonstrate 'In the middle of the ocean, the real luxury, is safety'

All Ovni boats are built from 5083 H 111 aluminium (hulls, decks, roofs and cockpits) and are fully assembled and welded in an Argon / Helium atmosphere. They are welded inside and out for extra security. Interior woodwork is in oak, with white vinyl headlining. Lead ballast is encapsulated in resin.

This cruise-ready Ovni 435 has many unique design features, as well as substantial improvements both inside and out.

"Ubi" has a lifting keel which gives her an enviable minimum draft of 74cm with the keel up and an impressive draft of 2.54m with the keel down. The most popular Ovnis for cruisers are the lifting keel version, as the boat is then immensely manageable around atolls and reefs, and can easily be beached for cleaning. With its 74cm minimum draft, you can go virtually anywhere.

The smooth and accurate helm control will say a lot for its nautical qualities: remaining both stiff in a breeze and efficient in performance. It is a Philippe Briand design after all!

With her generous forms and the quality of the installed amenities aboard, this boat will offer you exceptional comfort on board, both at sea and at anchor. The cabins are large, and the main cabin is spacious with enough space around the table to facilitate circulation. Interior wood is light oak, which contributes to a bright, modern feel without losing the traditional feel of a skilfully built yacht, where curved angles, joinery, cabinetry and attention to details are immediately obvious and far above what is often built these days.

The Ovni 435 is 12th off her series. She was launched in 2001 at the Sables D’Olonne in France before being sailed by her previous owner to the Caribean. her current owners, a family with 3 young children, purchased her 4 years ago after much searching for the perfect boat and sailed her extensively around the West Coats of the US and Canada before sailing down to Mexico and eventually crossing the Pacific to French Polynesia, where they blissfully spent the past year.

Over their 4 years ownership and the thousands of sea miles they have cruised on this lovely vessel, they have not once had a reason to regret their choice of vessel or doubt her sea-keeping qualities. 

Unfortunately it is now time to return home and for everyone to get back to school and work.

We are proud to bring Ubi to the market for you. She is a credit to her owners and will appeal to a discerning Ovni buyer. Ubi is sold turn-key, fully equipped for off-grid world cruising.

Ubi was also fully surveyed by an independent surveyor as part of the listing process for a clean bill of health and  to ensure a trouble free, easy passing of the flame to her buyers at a time where Covid restrictions can make logistics a little tricky.

You will find below an extensive list of information and specifications. We also have a comprehensive inventory which we can email you on request (there is just too much to put online!). A copy of the survey report is also available on request.

"We are an international family with 3 kids. Our dream was to one day break away from the crazy rhythm and get a sailboat to be able to voyage for a couple of years. What we really wanted was to spend way more time together, in a simpler way, closer to nature, and with adventures along the way. We looked for sailboats on the West coast of the USA and Canada (as we then lived in Portland, Oregon, USA), but didn’t find what we were looking for: a boat

-          That was big enough for the 5 of us, but small enough to be single handed (while the other one would be dealing with the kids)

-          That we could trust, really trust, in any condition, in any ocean

-          That was agreeable and comfortable at sea and at anchorage

-          That was simple and functional

-          That was environmental friendly

So we kept on looking and pretty fast, we were really attracted by the Ovnis. They checked all the boxes: spacious, with lots of headroom, a solid aluminum hull that is built for the worst conditions, bright interior and large cockpit with practical galley. We narrowed it down to an Ovni that we found in the Caribbean’s and finally bought Ubi in Martinique in 2017. After a couple of weeks of refitting, we left Martinique and island-hopped pretty quickly all the way to Florida. Mike still had his engineering job back home, so we had little time to waste. Once in Florida, we easily put Ubi on a truck that drove across the USA all the way to the NorthWest where we lived. The retractable keel made the road trip very easy, as Ubi could go under any highway bridge! Once in Portland, we kept on working on refitting Ubi for another couple of months. Our Caribbean adventure helped us determine what we wanted to improve or change. And then, we sold the house, cars, stuff and left in July 2018. We sailed up and spent the summer in beautiful British Columbia, Canada. We then slowly sailed down the west coast of the USA all the way to Mexico and spent a few months in the majestic Sea of Cortez. And in April/May 2019, set off to cross the Pacific from Mexico to French Polynesia. We arrived in the Marquesas after 25 days at sea, no big scare, and no breakage along the way! And since then, we have been enjoying the incredible sailing playground that is French Polynesia. Spending the Covid time here has been such a blessing. We were already boatschooling and had no job to be worried about. We’ve had so many kid boats around us for social interactions. We were (are) so lucky. During this time, what we have loved about Ubi is how autonomous we have been in energy and water, thanks to great solar panels that we installed early on. No need for a generator or to run the engine for energy. The solar panels have been enough for all our energy needs. It felt clean and simple. The other great advantage of Ubi over most monohulls has been its retractable keel. We have been anchoring most often in anchorages with approximately 1m depth, in sand just behind the coral reefs, and well protected from choppy conditions. It has been a blessing so many times for safety, but also for anchorage beauty, and to be with friends on catamarans… And finally, Ubi is beautiful and comfortable. It just feels good to be here. The brightness, the space, the nice woodwork. Ubi has definitely become our cocoon, our sanctuary.

Of course, there are always things to improve on a boat. And if we stayed longer on Ubi, we would probably buy a new gib, repaint the deck, or buy a new bimini and dodger. 

It is now time for us to leave this beautiful ocean life. Our kids are getting older and it is time for us to go back to land life. We do also need to get back to work, not only for monetary reasons, but also to participate more actively in a community and be part of something bigger. 

Ubi has literally been the vessel to our happiness for the last 4 years. And we are excited for her to do the same for the next adventurer/sailor/dreamer in line!" 



In the owner's words:

Reasons why we chose Ubi!

-       Seaworthy, very safe. She is a well renowned blue water sailboat. The famous around-the-world-sailor-and-writer Jimmy Cornell had the exact same model and crossed many oceans. In Europe, Ovnis have a great reputation and are considered as the “four wheel drives of the sea”

-       Aluminum hull

-       Retractable keel and rudder, with a minimum draft of 0.74m = 2'5" so we can anchor in very shallow places (it has been a real advantage in French Polynesia) 

-       Small enough to be handled solo or as a couple, yet big enough for a family of 5.

-       Plenty of headroom.

-       Plenty of storage room.

-       Exceptionally bright inside.

-       Designed with simplicity in mind.

-       Completely self-sufficient for water and power, at mooring as well as at sea for a whole family.

-       The Ovni Club ( is a very active community where you can get and provide as much help as needed.

Since purchasing Ubi in 2017, the owners made significant improvements for ocean passages and comfort aboard for their family of 5.

The owners made another round of improvements in 2020 with hope to sail west through the South Pacific, although Covid restrictions have forced them to change their plans and they now have to return home to the US.

Ubi arrived in French Polynesia in May, 10th 2019. There are no taxes on the purchase of second-hand boats for non-residents in Tahiti. Should you wish to stay in French Polynesia for some time after your purchase, Ubi is allowed to stay until May 10th 2022), plus an extra 6-mo available as extension due to COVID-19. After this the new owners will need to clear customs and come back to start another cruising permit, sail away to another adventures or import the vessel in French Polynesia.
