This 1990 Neptunus 52, Acionna, is a robust Dutch-built motor yacht offering a rare combination of significant mechanical investment and a highly coveted West Coast location. With a 52' LOA and a 14' 2" beam, this vessel provides the volume of a much larger yacht, featuring a thoughtfully designed layout for long-range cruising or local recreation.
Mission Bay Slip - A Rare Opportunity
A primary highlight of this offering is the vessel's current location. Acionna is situated in a highly desirable, inexpensive, and transferable slip in Mission Bay (subject to marina approval). This location offers the potential for extended stays at a reasonable cost, making it an ideal choice for those seeking a premium San Diego maritime lifestyle without the typical overhead.
Accommodations & Interior
The interior is defined by an open, airy feel with over 6' 6" of headroom throughout the main salon and cabins.
Twin Stateroom Layout: The private master stateroom is located in the forepeak with a queen berth and direct access to a "Jack and Jill" head featuring a dedicated shower. A second guest stateroom to starboard provides additional private quarters.
Chef's Galley: Reconfigured for modern convenience, the galley includes a Nova Kool refrigerator/freezer, Amzchef induction stovetop, SPT dishwasher, and a Frigidaire microwave.
Climate & Comfort: Equipped with a Cat Pumps water maker (pickled) and an 11kW Westerbeke generator to support all AC systems while at anchor.
Flybridge & Cockpit
Designed for the Southern California lifestyle, the exterior spaces are expansive and versatile.
Expansive Flybridge: Protected by a stainless steel framed Bimini with gray canvas, the flybridge offers immense seating capacity and a high-visibility vantage point for navigation.
Cockpit & Swim Step: The large cockpit is designed for multi-use, featuring multiple rod holders for fishing and a seamless transition to the extended swim step. A Whale swim step shower adds convenience for water activities.
Performance & Major Mechanical Refits
Acionna has benefited from over $60,000 in documented mechanical upgrades and maintenance between 2020 and 2025, ensuring reliable performance from the Twin Volvo Penta TAMD 71A diesel engines (360 HP each).
Fuel System (2025): Two brand-new aluminum fuel tanks (430-gallon total capacity) were professionally installed in March 2025 ($22,595).
Engine & Cooling Refit (2020-2025): Extensive cooling system overhaul including new turbos, sea water pumps, heat exchangers, and transmission oil coolers. Recent 2025 service included new seawater impellers and a full oil/filter change.
Navigation: A complete Simrad electronics suite with NSS12 and NSS8 displays, radar, sonar, and ComNav 1101 autopilot.
