1999 Bayliner 4085 Avanti Sunbridge – Freshwater Liveaboard Luxury with Big-Block Power
Current location: Sarnia, Ontario, Canada
The Bayliner 4085 Avanti Sunbridge earned a loyal following by delivering an incredible amount of light and airy space, comfort, and cruising capability at a highly competitive price point—and this exceptionally well-kept freshwater example is no exception. Powered by twin MerCruiser 8.2L MAG MPI big-block gas engines with only approximately 575 original hours, this 40-foot express cruiser shows beautifully and has been maintained to a very high level.
Designed with liveaboard comfort in mind, the spacious mid-cabin floorplan features two private staterooms with privacy doors, a large convertible salon lounge, and a fully equipped galley that rivals many larger motor yachts. Whether you're planning weekend cruising, extended stays aboard, or entertaining friends and family, this Avanti delivers impressive comfort and functionality throughout.
The salon is bright and airy and inviting with sunlight flooding in through the large side windows (no small ports here) with generous seating, a full-size refrigerator, stovetop, microwave, and heat and air conditioning for comfort in any weather. The private head includes a separate stand-up shower, while the mid-cabin stateroom offers additional seating and excellent use of space.
At the helm, updated Raymarine chartplotter GPS electronics provide reliable navigation, while the professionally installed JL Audio sound system—with dedicated amplifiers and three 10-inch subwoofers—creates an incredible entertainment experience underway or at anchor.
The cockpit layout is equally impressive, featuring a double-wide helm seat, large circular aft lounge with removable table, wet bar, new Sea Deck cushioned marine flooring (2026) and newer canvas tops. The extended swim platform provides excellent access to the water and can even accommodate a personal watercraft.
If you’ve been searching for a freshwater cruiser that offers true liveaboard comfort, strong performance, exceptional condition, and tremendous value, this 4085 Avanti Sunbridge deserves serious consideration.
