OVERVIEW

The Bayliner 4550 Pilothouse Motor Yacht, (also known as the 4588 from 1989 to 1993), is known for its practical, spacious, and comfortable design. It is well-regarded for its reliability and seaworthiness. Hubba-Hubba is an exceptional example of the 4550 model, featuring numerous upgrades and enhancements. Having been under the same ownership for over 23 years, the vessel has undergone many refits and improvements. With only 705 hours on the dependable twin turbo Hino EH-700T diesel engines, Hubba-Hubba is equipped to provide safe and enjoyable cruising experiences. The yacht offers three staterooms, two heads each with stall showers, a covered cockpit, a spacious main salon with an up galley, teak and holly flooring, warm teak wood cabinetry throughout, updated upholstery and finishes, heating and air conditioning, a raised pilothouse, and a large flybridge with abundant built-in seating for both crew and guests.
