This documented maintenance history and relatively low operating hours signal conscientious ownership and mechanical reliability.
Layout and Cabin Design
The main cabin exemplifies thoughtful layout prioritized for cruising couples. North American white ash interior joinery creates a warm, traditional ambiance that resists the cold, sterile feel of modern production boats. The galley-up arrangement positions the cook at a starboard-side counter engaged with the salon's social space rather than isolated in a separate galley—a design choice that reflects the owner's understanding of liveaboard comfort and entertaining while underway. To port, a convertible L-settee with a hi-low table provides flexible seating and sleeping arrangements; the table's adjustable height accommodates both dining and conversion to berth mode. A reclining chair forward of the settee adds another seating option for evening relaxation or reading. The helm station, positioned forward of the galley, is wide enough to accommodate two tall helm chairs—a practical detail for a couple managing watch rotations during extended passages. A starboard-side helm door is a significant operational advantage, allowing the helmsman to step directly outside for docking, lock transits, and line handling without leaving the helm or requiring crew coordination through interior passageways. This design feature dramatically improves safety and situational awareness, particularly in confined waters. Steps descend from the port side of the salon to the lower cabin, where port-side storage lockers provide organized stowage for cruising gear. A large head to starboard serves the main cabin area. The owner's cabin forward features a centerline island berth—a premium sleeping arrangement that provides storage access on both sides and superior comfort for extended cruising. Three large opening windows with screens throughout the main cabin ensure natural ventilation and light. Parquet flooring with bound carpet rugs, shades for windows, a clock, and barometer set in the owner's cabin reflect attention to both functionality and aesthetic refinement. The vessel's overall storage capacity is notably generous for a 37-footer, a deliberate feature that supports the extended-cruising lifestyle without requiring constant inventory management or frequent provisioning stops.
