Meet UNDRA
UNDRA is our floating home and transportation about the world.
In Swedish, 'undra' means to wonder, to be in awe, to be curious about. For us, curiosity is our compass and this is the vessel that transforms our wonder into into experiences.
She is a 2023 Dutch-built, aluminum 50-foot long-range explorer yacht designed for remote voyages and sustainable living.
But the wildest part? We won her at auction.

Yep, we scored a $2 million explorer yacht for half price. Granted, she had never been fully commissioned and had sat tied to a dock for more than two years. And boats DO NOT like to sit. So while it was a great deal, there was still a lot of work and teething issues to be sorted out. But after almost a decade of sailing around the world, boat work is an area we are well versed in.

UNDRA
(noun) Pronunciation: (OON-drah)
Built for the Edges of the Earth
If Captain Nemo were to trade his Victorian submarine for a modern pocket explorer, it's easy to imagine him choosing something like UNDRA.
A vessel built for range and reliability over unnecessary luxury (without sacrificing comfort). Where the Nautilus vanished beneath empires, UNDRA slips quietly between them. Compact yet capable, her bare aluminum hull is built for icy high-latitude waters, and her systems are designed for life off-grid. Yet her warm interior makes the sea feel like home.
We can endure any season and voyage further than most, letting UNDRA carry us into the margins where the world still feels vast and wild.
Born for the Harsh and the Beautiful
- 7 mm Aluminum Hull: Strong enough for high-latitude waters, floating debris, and the realities of remote cruising.
- Transatlantic Range: A 340 hp engine and 3,000 liters of fuel give UNDRA an estimated range of more than 3,000 nautical miles.
- Fast-Displacement Hull: Her 19.5-tonne hull balances fuel efficiency with the ability to make speed when conditions demand it.
- Self-Sufficient Power: Solar and wind generation help us stay off-grid longer while reducing generator use.
- Surprisingly Spacious: Three queen-size cabins, three heads, and a chef-friendly galley make this 50-footer feel much larger.
- Go-Anywhere Draft: A 1.2-meter draft opens up shallow anchorages and remote coastlines many yachts cannot reach.
- All-Weather Pilothouse: Heated and Air Conditioned comfort, 360-degree views, and three helm stations keep us moving in almost any weather.
- Toughened Windows: Insulated glazing makes UNDRA quieter, safer, and more energy-efficient.
- Inland-Waterway Ready: A folding mast reduces the air draft from 7.2 meters to 3.4 meters.
- Sustainably Built: Recyclable aluminum, cork decking, Scandinavian oak interiors, and Ecospeed coating reduce long-term environmental impact.

But UNDRA Isn't Perfect...Yet.
We have a few upgrades we want to make. We prioritize upgrades based on how we actually live aboard. Since 90% of cruising life happens at anchor, that’s where efficiency matters most. And that is where we will focus first.

- Battery Upgrade: Batteries are the heart of any world cruising yacht. They power everything from our radar for spotting storms to our navigation gear and satellite communications. Right now UNDRA has a large AGM house battery bank. Which is ok but not optimal.
- Kite Power: The vessel was designed and reinforced for a kite. The idea is compelling...but the right system has not revealed itself yet.
- Hybrid Comfort, Extended Range: Right now she has solar, wind generators, a high output alternator and an efficient diesel engine. Ideally, we want to pair all of that with an electric motor for even greater autonomy. But so far, we haven't found the perfect setup.
The Mission Ahead
Our mission is to document life in extreme latitudes and share stories from some of the most remote corners of the planet.
As always, we’re inviting you aboard for the journey, the challenges, and UNDRA’s transformation as we prepare her for the wild.
From Sailing to Motor Yacht?!
This is our third bluewater, ocean crossing vessel. Our previous vessels were both Sailing Catamarans named CURIOSITY. So UNDRA marked a dramatic change—and the beginning of an entirely different kind of adventure for us. You can follow the story of our first catamaran purchase back in 2016, our second in 2021.
