2016 Aspen C105 Power Catamaran for Sale in Seattle, WA
Overview
The 2016 Aspen C105 represents a thoughtfully engineered approach to mid-sized cruising, combining the fuel efficiency and stability advantages of a power catamaran hull with practical deck design and modern onboard systems. Built by Aspen Power Catamarans in the Pacific Northwest, this 34.5-foot vessel is powered by a single Volvo Penta D3 diesel engine and maintains a one-owner history with documented care and significant recent upgrades. At a 10-foot beam and displacement-friendly hull form, the C105 achieves a cruising speed of 16 knots while delivering fuel consumption in the range of 7 to 7.5 gallons per hour at 17 knots—a meaningful efficiency metric for owners planning extended cruising seasons or frequent weekend departures. The Aspen C105's design philosophy prioritizes roll stability and interior volume without requiring the operational complexity or fuel appetite of larger monohull cruisers. The catamaran's asymmetrical hull geometry, patented by Aspen, generates approximately 70% greater roll stability than comparable single-hull designs while reducing draft and environmental impact. For Pacific Northwest boating—where protected waters, island cruising, and variable weather are routine—this combination of seakindliness and efficiency addresses real owner priorities rather than marketing abstractions.
Hull Design and Stability
Catamaran hulls have long been associated with shallow draft and interior volume, but Aspen's asymmetrical power catamaran design departs from traditional twin-hull geometry. Rather than symmetrical hulls of equal displacement, the C105 uses an offset arrangement that maintains the beam advantages of a catamaran while improving directional stability and reducing the squat effect common in traditional catamarans at displacement speeds. This engineering choice directly supports the vessel's cruising profile: comfortable, predictable, and economical over long distances. The 10-foot beam provides generous interior width without sacrificing marina slip compatibility or creating excessive windage. The hull form supports easy single-handed operation and reduces the learning curve for owners transitioning from monohull experience. Stability underway—particularly in beam seas—is a measurable advantage of the catamaran platform, reducing the need for active stabilization systems and contributing to the comfort profile that makes extended cruising less fatiguing.
Helm and Navigation Systems
Scout is equipped with a comprehensive electronics suite supporting safe navigation and situational awareness. A GPS chartplotter, radar, and autopilot form the foundation of the helm station, allowing the owner to manage passage planning, monitor weather and traffic, and maintain course in variable conditions. An AIS receiver adds vessel traffic awareness, particularly valuable in busy waters near Seattle and throughout the Strait of Juan de Fuca. The helm layout supports both active piloting and autopilot-assisted cruising, reducing fatigue on longer passages and allowing the operator to manage other vessel systems or attend to guests. The inclusion of a secondary navigation and control station—standard on many cruising catamarans—is supported by the vessel's design, though specific details of the helm layout are best confirmed during a viewing.
Propulsion and Fuel Efficiency
The Volvo Penta D3 diesel is a proven, compact marine powerplant widely recognized for reliability and fuel economy in the mid-range cruising segment. With approximately 1,144 operating hours, the engine represents moderate service life for a 2016 build. Recent mechanical investments—including a new turbocharger, new fuel injectors, and comprehensive maintenance with documented records—indicate the owner's commitment to preserving engine condition and performance. Fuel consumption at 17 knots of approximately 2 to 2.5 nautical miles per gallon (or 7 to 7.5 gallons per hour) translates to tangible operating economics. An 80-gallon fuel capacity supports a range of roughly 160 to 200 nautical miles at cruising speed, suitable for Pacific Northwest island hopping and weekend passages. The efficiency advantage of the catamaran hull—requiring less horsepower to achieve comfortable cruising speeds compared to a heavier monohull—directly supports these fuel consumption figures. Maximum speed of approximately 22 knots provides reserve performance for crossing open water or exiting weather systems, though the vessel's sweet spot remains the 16-knot cruising regime where fuel economy and comfort align.
Deck Layout and Outdoor Living
The C105's deck design prioritizes usable outdoor space and weather protection. A hardtop structure over the main cockpit provides shade and weather protection, extended by a custom full canvas enclosure fabricated and installed during the vessel's ownership. This customization significantly expands the usable cruising season in the Pacific Northwest, allowing the owner to entertain, dine, or simply enjoy the view during rain or cool weather without retreating to the cabin. The wide beam and catamaran platform provide a stable, non-heeling deck—a comfort advantage for guests and crew, particularly during meal preparation or when moving about underway. Bow and stern thrusters enhance docking and maneuvering precision, reducing the physical demand of boat handling in tight marina situations or strong current conditions. An electric windlass with dual anchor rode systems supports confident anchoring in the San Juan Islands and other protected Northwest cruising grounds. The dinghy package—included in the vessel's equipment—extends the reach of cruising by providing transportation to remote anchorages and shore exploration without relying on marina infrastructure.
Cabin and Interior Accommodations
While specific cabin layout details are best explored during a vessel viewing, the C105 is engineered to maximize interior volume within its 34.5-foot length and 10-foot beam. The catamaran's wide platform and flat cabin sole support efficient cabin planning, with dedicated sleeping quarters, a functional galley, and head facilities configured for comfortable extended cruising rather than bare-bones weekending. The galley is fully equipped with a microwave, oven, and refrigeration—appliances that support meal preparation and provisioning for multi-week cruising seasons. A 50-gallon fresh water capacity, paired with heating and hot water powered by a Wallace diesel furnace, enables comfortable showering and dishwashing underway. The furnace provides cabin heating during cool-weather cruising, essential for Pacific Northwest seasons when water temperatures remain low and cabin warmth directly impacts comfort and safety. The inverter system—recently upgraded as part of the $50,000+ recent investment—supports 120-volt appliance operation while at anchor or away from shore power, extending the vessel's self-sufficiency. A shore power system enables full electrical recharging and comfort when docked at marina facilities.
Power and Energy Systems
Scout's electrical architecture reflects modern cruising priorities. The lithium battery system—upgraded as part of recent improvements—offers weight savings, faster charging, and longer cycle life compared to traditional lead-acid banks. This upgrade directly supports the inverter's ability to deliver sustained 120-volt power, enabling microwave and oven use without relying on the diesel engine or shore power. Solar panels contribute to battery charging during daylight hours, reducing fuel consumption and engine running time while at anchor. This combination of solar generation and lithium storage supports quiet, low-impact cruising in environmentally sensitive anchorages and reduces the operational cost of extended stays away from marina facilities.
Recent Upgrades and Maintenance
The documented $50,000+ in recent investments represents a meaningful commitment to mechanical and systems integrity. New turbocharger and fuel injectors address the core engine systems, improving reliability and efficiency. The new riser installation supports proper engine cooling and reduces corrosion risk in saltwater operation. Fresh bottom paint maintains hull protection and reduces drag, supporting the vessel's fuel economy performance. Extensive maintenance with available records provides transparency into the vessel's service history and allows prospective buyers to assess the owner's stewardship. The combination of factory-engineered design, one-owner operation, covered storage, and documented upgrades positions Scout as a vessel that has been maintained with knowledge and care rather than deferred or neglected.
