This 2005 Ocean Alexander 42 Altus offers an excellent combination of traditional craftsmanship, comfortable accommodations, and serious cruising capability. Designed by Ed Monk Jr., the Altus is known for its quality construction, beautiful teak interior, and practical layout, making it a particularly appealing yacht for extended cruising in the Pacific Northwest and beyond.

Powered by upgraded twin 440 HP Yanmar 6LY2A-STP diesels with approximately 1,440 hours, she features straight-shaft propulsion, ZF transmissions, and a KeyPower bow thruster.

One of the most significant highlights of this vessel is the extensive professional mechanical service completed between September 2025 and January 2026, totaling more than $29,000 in documented invoices.

Both Yanmar engines underwent comprehensive cooling-system service, including removal, professional cleaning, and pressure testing of the aftercoolers, heat exchangers, and oil coolers. The components were reinstalled with replacement OEM Yanmar molded hoses, seals, and gaskets, followed by fresh coolant. Both engines and transmissions were serviced, along with substantial work to the Northern Lights generator. A January 2026 sea trial documented satisfactory engine temperatures and cooling-water flow.

Interior & Accommodations

The interior showcases the craftsmanship Ocean Alexander is known for, with extensive teak cabinetry, paneling, and joinery throughout. Large salon windows provide excellent natural light, while a concealed television on an electric televator maintains the salon's clean appearance when not in use.

The galley is located forward to port and features granite countertops, teak and holly flooring, a Nova Kool refrigerator, Kenyon electric cooktop, GE convection microwave, U-Line icemaker, and generous storage.

Below, the two-stateroom, two-head arrangement provides comfortable accommodations for owners and guests. Both heads feature granite countertops and upgraded Tecma electric toilets with replacement sanitation hoses.

Flybridge & Exterior

The spacious flybridge features upgraded helm seating and a custom Canvas Supply enclosure installed in 2020 at a reported cost of $28,000. This fully enclosed upper helm provides excellent protection from the elements and extends the comfortable cruising season.

An electrically assisted folding radar arch offers flexibility for covered moorage.

Additional deck equipment includes a Maxwell 1200 electric windlass, stainless steel 45 lb plow anchor with 300 feet of chain, bow washdown, and a Seawise hydraulic-assist tender davit system. An Apex inflatable dinghy with a 20 HP outboard is also included.
