Details

Built for serious adventure cruising and high-latitude expeditions, this yacht was designed by the legendary Dick Koopmans Senior, a name synonymous with practical, no-nonsense offshore design. Crafted in aluminium, this metal-hulled yacht is purpose-built for extended voyages in demanding conditions — from the fjords of Patagonia to the ice-strewn routes of the Northwest Passage.She’s powered by a near-new Yanmar 54HP diesel engine (2022) with low hours (400), and equipped with a full suite of upgraded electronics and new sails (2021), including a ProFurl in-boom furling system for ease of handling under way.Her lifting keel and shoal draft design make her ideal for exploring shallow anchorages and uncharted coastlines, without compromising bluewater performance. She’s a true all-ocean cruiser, equally at home in tropical waters or navigating icy Arctic passages.A full record of the build process is available — a rare advantage that gives valuable insight into the yacht’s craftsmanship and attention to detail.Highlights Include:

2 Raymarine Axiom chartplotters with AIS (2021)

Yanmar 54HP engine (new in 2022, approx. 400 hours)
ProFurl in-boom furling main

New mainsail, genoa, and staysail (2021)

Parasailor (150m²) – excellent for light wind passagemaking

Electric windlass (2022)
Full cockpit enclosure/tent

8-person liferaft, serviced through 2026
Real-World InspirationIf you’re dreaming of following in the footsteps of sailors like Skip Novak, or plotting your own path through remote waters, take a cue from those out there doing it:

John and Kara Pennington took their Koopmans 46 „Sentijn“ through the Northwest Passage, sailing as a family in one of the most remote and stunning routes on earth. Their journey is captured in the book Thicker Than Ice and on YouTube.

Juho Karhu and Dr. Sohvi Kangasluoma, creators of „Alluring Arctic Sailing“ on YouTube, sail their aluminium yacht s/v Lumi through Arctic waters, including a successful Northwest Passage and overwintering in Greenland.
