Cobalt 255: BoatTEST Review
Overview
The 2005 Cobalt 255 is a 25-foot closed bow boat designed to combine the agility of a sport boat with the comfort and amenities of a cutted cabin cruiser. Developed as an evolution of the popular 250 model, the 255 adds overnight capability and a center walk-through, catering to customers seeking both performance and practicality. Cobalt emphasizes safety, comfort, and quality craftsmanship, all supported by an industry-leading warranty.
Exterior Design and Deck Features
The 255 features a heavy-duty flip-down step that facilitates easy access to the dash and bow area. Safety and convenience are enhanced by docking lights and a stainless steel scuff plate that protects the boat during trailer loading. The anchor locker at the bow is equipped with a gas-assist shock to keep it open during tackle work. On the companion side, storage is thoughtfully integrated with a slash pocket, stainless steel cup holder, grab handle, and a mesh chart pocket. Seating includes bucket seats with slide, swivel, and spin adjustments, allowing the driver to maintain visibility of skiers or engage in conversation while at anchor. The stern includes extended swim platforms with nonskid surfaces, stainless steel rails, and an easily deployable swim ladder. A dividable locker in the stern doubles as a large ice cooler, and a tow post is positioned for optimal line placement.
Interior Living Spaces
The cabin of the Cobalt 255 is designed with comfort and usability in mind rather than as a mere storage space. It offers generous seating that wraps from port to starboard, creating a welcoming environment below deck. A port-a-potty is conveniently located behind the stairs for easy access. The galley area features a Corian countertop with storage underneath, and the cabin is equipped with a stereo system and two 12-volt power connections. For extended comfort, filler cushions can be added to convert the seating into a nap or sleeping area. The flooring is finished with snap-in carpet that extends toward the walk-through transom, enhancing the cabin’s cozy ambiance.
Power and Performance
The 255 is powered by a Volvo 8.1 GI stern drive paired with a Penta Dual Prop Out Drive and F6 counter-rotating props, delivering excellent acceleration and handling characteristics. This large displacement engine features electronic fuel injection and controls for quick throttle response and reliable starting in all weather conditions. The stern drive is engineered to maintain planing at low RPMs, optimizing fuel efficiency. An active corrosion protection system is standard, and the Ocean Series option is available. Performance testing showed the boat planes in just 3.9 seconds, reaches 30 miles per hour in 6.9 seconds, and cruises economically at 2,500 RPM with a speed of 28.1 miles per hour consuming 8 gallons per hour, yielding a range of 231 miles. The top speed achieved was 55 miles per hour at 4,600 RPM at wide open throttle.
Private Accommodations and Storage
The cabin’s overnight accommodations are well thought out, providing ample space for resting and privacy. The port-a-potty is discreetly tucked behind the stairs, and storage compartments are plentiful, including beneath the Corian countertop and within the engine hatch area. The engine compartment also features a wakeboard rack, maximizing utility without sacrificing space. Stern bench seating offers additional room for passengers, with optional filler cushions to create a larger lounging area.
Conclusion
The 2005 Cobalt 255 exemplifies a harmonious blend of performance, luxury, and practical design. It excels in fit and finish, offers a comfortable and spacious cabin, and delivers strong, efficient performance on the water. With thoughtful safety features and user-friendly amenities, the 255 stands out as a versatile and well-engineered boat in the 25-foot class.
