Boathouse Kept - Transferable Van Isle Marina Boathouse Moorage

The finest Ocean Alexander 520 Pilothouse on the market!

This is an outstanding example of a thoughtfully upgraded and meticulously maintained cruising yacht that has benefited from extensive professional improvements over the past several years. Rather than simply maintaining the vessel, the current owner has continually invested in modernizing every major system—from propulsion and electrical to navigation, anchoring and cruising amenities—resulting in a truly turnkey yacht ready for extended Pacific Northwest cruising or offshore adventures.

Whether you're planning weekends in the Gulf Islands or extended voyages to Alaska, this yacht delivers the reliability, comfort and capability that experienced cruisers demand.

The navigation systems have been completely modernized with a premium Garmin electronics suite featuring dual 12-inch touchscreen multifunction displays at the lower helm, a 12-inch touchscreen display at the upper helm, Garmin autopilot, repeater displays at both stations, high-definition color radar and an integrated AIS system. The lower helm dashboard was professionally rebuilt to accommodate the upgraded electronics, and the entire network is seamlessly managed through Garmin ActiveCaptain.

Mechanically, the yacht has received exceptional care. The starboard engine was professionally rebuilt with a new long block and all accessories at approximately 851 hours and currently has approximately 350 hours since replacement. The port engine has undergone a comprehensive mini-overhaul including a new turbocharger, new injectors, timing adjustment, and complete removal and cleaning of the intercooler and oil cooler. Following the rebuild, the starboard engine received its scheduled valve adjustment during the break-in period. Both propeller shafts have also been upgraded with PSS dripless shaft seals for dependable, low-maintenance operation.

The electrical system has been professionally surveyed and extensively upgraded by Prime Yacht Systems, providing modern charging capability and exceptional reliability. Improvements include new engine start batteries, generator battery, dedicated bow and stern thruster batteries, Victron charge controllers, DC-to-DC charging systems, Victron SmartShunt battery monitoring, rebuilt alternators, upgraded battery cable terminations, ABYC-compliant fuse protection, a smart external alternator regulator, Starlink integration, GPS output to the VHF radios and the addition of a convenient 120-volt receptacle at the lower helm.

Designed with extended cruising in mind, the yacht has also received numerous comfort and self-sufficiency upgrades including an 840-watt solar array, Seamaker 40 GPH watermaker, new Webasto Hydronic diesel heating system, new Raritan 20-gallon hot water tank, Marco electronic freshwater pressure pump, upgraded saltwater washdown accumulator and a new oil change system.

The ground tackle system has been completely renewed by Philbrooks with a new Maxwell windlass, 400 feet of new 3/8-inch chain, an Excel No. 9 anchor and a modified bow pulpit designed specifically for the upgraded anchoring system. This provides outstanding holding power and confidence whether spending the night at anchor or cruising remote destinations.

The flybridge has also received significant attention with a renewed enclosure featuring new Eisenglass, upgraded captain's chairs, reconfigured aft seating for improved comfort, a new Mathers MMC electronic control system and a new upper helm VHF radio. A heavy-duty one-ton Steelhead crane makes launching and retrieving the tender effortless.

The tender package is equally impressive, featuring a new Yamaha 25 HP outboard with new throttle controls, Garmin Striker 4 Plus fish finder, new transducer and custom aluminum mounting plates for Scotty downriggers, creating a highly capable platform for exploring, fishing or running ashore.

Every improvement reflects an owner who has spared no expense in maintaining and upgrading this yacht to an exceptional standard. Opportunities to purchase a vessel with this level of documented investment, thoughtful modernization and mechanical care are increasingly rare.
