Aspen’s C110 and C128S Sport bring outboard power to cruising catamarans, while Carbon Cat offers lightweight tenders for both sail and powerboat owners.
Aspen Power Catamarans is showcasing two of its newest outboard-powered cruisers at the 2026 Annapolis Powerboat Show: the 37-foot C110 and 44-foot C128S Sport. Alongside the larger boats, the company’s Carbon Cat tender line gives cruisers another option to explore for trips between boat and shore.
Built in Burlington, Washington, Aspen’s boats use the company’s patented PROA catamaran hull design, with differently sized hulls intended to improve efficiency while providing a stable ride. The two models take that approach in different directions, from a trailerable cruiser to a three-cabin boat with a flybridge.
Aspen C110: A 37-Foot Outboard Cruiser
The C110 builds on Aspen’s outboard cruiser line with Mercury engines, digital throttle and shift controls, and electronic steering. Aspen says the 37-footer remains trailerable in all 50 U.S. states.
Buyers can choose a 175-horsepower engine on the narrower hull paired with a 225-horsepower engine on the wider hull, or twin 225-horsepower outboards. According to Aspen, the twin-225 configuration delivers a top speed of 34 mph.
The model also addresses the practical side of cruising away from shore power. Optional 115-amp alternators can support onboard loads, including 17,000 BTUs of air conditioning, while recharging lithium iron phosphate battery banks. Aspen says the battery system can power onboard systems during overnight stays without a generator.
An extended waterline supports the larger outboards and allows a tender carried on Aspen’s EZ Davit to sit farther aft, freeing space in the cockpit.
C128S Sport: More Room for Life Aboard
At 44 feet, the C128S Sport is the largest Aspen to feature outboard power to date. The twin-engine cruiser combines the company’s PROA hull design with accommodations that include a fully equipped galley, three cabins, and two heads. The owner’s suite features a king-size bed.
Two helm stations give the skipper a choice between the climate-controlled cabin and the flybridge. Aspen reports a cruising speed of 22 mph at 3,800 rpm and says the Sport version adds 4–5 mph of top-end speed. The company also reports an efficiency improvement of 10 percent or more at a 19 mph cruise, though the release does not specify the comparison conditions.
Carbon Cat: A Lightweight Tender Option
For sailors and powerboaters looking at their next tender, Aspen’s Carbon Cat lineup includes five models with tiller-steered and console-driven configurations. The lightweight rigid tenders use carbon fiber construction and a distinctive hull form designed for stability, a dry ride, and efficient operation with moderate horsepower.
Lower boat and engine weight can make a difference when stowing, launching, and retrieving a tender. Carbon Cat also offers optional transom wheels to simplify moving the boat onto a beach.
