The Arksen 55 strips back the conventions of motor yacht design and replaces them with something more purposeful. At 17.3 metres, this aluminium explorer is engineered to reach remote coastlines, operate off-grid for days, and still deliver a 50-knot sprint when the weather window demands it. Designed by Jarkko Jamsen and built by Kewatec, Finland’s most respected professional vessel builder, every panel is marine-grade aluminium, fully repairable and recyclable at end of life.
The double-stepped deep-V hull sits shallow enough to nose into rocky inlets and anchor close to shore, while the bow ramp provides direct sea-to-land access without a tender. Below decks, flexible accommodation sleeps between four and eight across cabins finished in one of two interior palettes: Nordic Light or Nordic Dark. A below-deck utility zone combines the galley with a practical workshop, drying cabinet, and modular storage, keeping the main saloon free for living.
Solar panels and battery packs support extended time at anchor without running a generator. Heated, openable windows maintain visibility and fresh air in any climate. The Arksen 55 earned its First Edition programme a guaranteed buy-back value written into the purchase contract, a level of confidence rare in new-build boat sales. From €1,999,000, she represents a new category: a vessel designed equally for a Channel crossing and a week anchored in a Norwegian fjord.

Fifty knots from a 17-metre explorer hull is a headline number, but the Arksen 55’s real performance story is range. At 350 nautical miles, she can cover serious coastal passages without refuelling, opening up routing options that fuel-limited tenders and day boats cannot match. The double-stepped deep-V hull design, engineered in partnership with Aivan, balances high-speed efficiency with low-speed stability, keeping the ride comfortable whether threading through island channels at displacement pace or making a dash across open water. Shallow draft opens rocky inlets and tidal anchorages to a vessel that would otherwise need a tender to access them. Kewatec’s aluminium construction contributes to a strong power-to-weight ratio, and the stepped hull reduces wetted surface at speed, improving fuel economy where it matters most: during the long legs between adventure stops.
Jamsen’s exterior is functional before it is decorative, and looks better for it. The Arksen 55’s profile is low and purposeful, with a raked bow that accommodates the deployable ramp for direct shore access. The wheelhouse sits forward, giving the helmsperson clear sightlines in every direction, while heated, openable windows maintain visibility and ventilation in cold-weather cruising grounds. The aft deck is configured for activity: space for diving equipment, fishing gear, kayaks, or a small tender, with the stern platform providing water-level access. Solar panels sit flush on the superstructure, feeding battery packs that sustain hotel systems at anchor. Every surface is marine-grade aluminium, a material that weathers honestly and repairs simply. The colour palette and detailing avoid chrome-and-teak marina fashion in favour of a workboat clarity that signals purpose.
Arksen offers two interior palettes, Nordic Light and Nordic Dark, both designed to create calm after a day on the water. Materials are tactile and resilient: surfaces feel refined but will not punish real use. The layout accommodates between four and eight guests across flexible sleeping arrangements, with full standing headroom throughout the lower deck. A unique four-door layout and dual side walkways route foot traffic around the main cabin, preventing the congestion common on boats this size. Guests can move from the aft deck to the lower cabins without disturbing anyone in the saloon, a circulation strategy more common in residential architecture than yacht design. The full-beam saloon above is uncluttered by corridors, offering a single open living space that feels significantly larger than the hull’s 4.7-metre beam would suggest.
Below the main deck, a dedicated utility zone combines the galley with a workshop, drying cabinet, washing machine, dryer, and dishwasher. This arrangement frees the upper saloon entirely for living and keeps the operational side of cruising contained and accessible. Modular shelving with semi-transparent storage boxes keeps equipment organised, whether the trip calls for dive gear, fishing tackle, or film-making equipment. The solar and battery system is designed for genuine off-grid capability, not the token panel seen on most production boats. At anchor, the Arksen 55 can sustain essential systems without a generator, reducing noise and emissions in the sensitive environments where her owners are most likely to be. Analogue switches and accessible components put vessel operation directly in the owner’s hands, a deliberate design choice that favours simplicity and self-reliance over touchscreen complexity.
Kewatec, the Finnish yard responsible for the Arksen 55’s construction, has decades of experience building naval, rescue, and Arctic vessels. That pedigree shows in every weld: marine-grade aluminium throughout, a hull that is both repairable at any boatyard worldwide and fully recyclable at end of life. Arksen’s First Edition programme adds a guaranteed buy-back value written into the purchase contract, fixing a floor price on the day of order. Owners who move on can hand back the keys for the guaranteed sum, trade up to a larger Arksen with a premium applied, or let the guarantee lapse and sell privately. Ten percent of Arksen’s proceeds fund ocean conservation through the 10% for the Ocean initiative, supporting over 70 organisations across 27 countries. Starting from 1,999,000 euros, the Arksen 55 targets a buyer who values build integrity, environmental responsibility, and genuine capability over the surface signifiers of conventional yacht ownership.
