George and Stacey Sass have decided it is time to downsize from their 43-foot boat, and now they face the question every cruiser must consider: what vessel will best suit their changing needs? Downsizing is about trade-offs—comfort versus manageability, cruising range versus efficiency, and onboard systems versus simplicity. For many boat owners moving to a smaller platform, a modern power catamaran can offer an appealing combination of space, stability, fuel economy, and easy handling. One candidate that often comes up in these conversations is the Aspen C90.
Aspen C90
Designed by Larry Graf, the Aspen C90 is an innovative power catamaran that departs from traditional twin-hull symmetry. Graf, who is known for founding Glacier Bay Catamarans, developed the Aspen with asymmetrical hulls and an emphasis on efficient, single-diesel propulsion. These design choices aim to deliver a quieter, more fuel-efficient ride while preserving the interior volume and stability owners expect from a catamaran.
As an option for boaters looking to downsize, the Aspen C90 highlights several advantages typical of modern power cats. The twin-hull layout naturally provides a broad, stable platform, reducing roll and improving comfort underway and at anchor. Asymmetrical hulls can be optimized to improve efficiency through the water, which in turn allows a single diesel engine to deliver the range and performance traditionally associated with twin-engine installations. For owners who are simplifying systems and lowering maintenance demands, a single-engine setup can be an attractive trade-off.
When considering a transition from a 43-footer to something like the Aspen C90, practical factors to evaluate include interior space planning, storage, maneuverability in tight marinas, and the overall fuel and maintenance profile. Power catamarans often offer deep, wide salon areas and multiple forward and aft cabins, creating a livable layout that feels larger than comparable monohulls of the same length. For cruisers who spend extended time aboard or host guests, the ability to retain generous living areas while reducing overall vessel size is a major selling point.
Other considerations include accessibility of systems, ease of docking, and visibility from the helm. Many modern catamarans place the helm with excellent sightlines and simplified control stations, which helps single-handed or short-handed owners feel confident during docking and close-quarters maneuvers. Fuel consumption and engine access are also critical: a single diesel can simplify maintenance routines and reduce parts inventory, but it’s important to verify that redundancy and reliability meet your cruising plans and comfort level.
For George and Stacey—or any owner contemplating a move to a smaller boat—the decision should balance lifestyle goals with practicalities. Are weekend getaways the primary focus, or do extended coastal passages and liveaboard comforts remain a priority? How important are dock fees and storage costs relative to onboard amenities? And how much value is placed on lower maintenance and simpler systems?
Talking with owners of similar vessels, arranging sea trials, and spending time aboard potential candidates will help clarify the right choice. The Aspen C90, with its inventive approach to hull design and single-diesel operation, represents one modern alternative that could suit couples looking to downsize without sacrificing comfort or range.
