1978 Marine Management Flybridge Commercial Passenger for Sale — Mount Desert, ME, US

This 1978 Marine Management passenger boat is a purpose-built, heavily constructed vessel designed for continuous commercial service, evidenced by its USCG certification for 42 passengers and 2 crew. It has a proven history as both a dive boat and passenger ferry, indicating its versatility and robust design.

From a construction standpoint, the Marine Management hull is solid fiberglass, semi-displacement, and built to last. This is not a recreational hull adapted for commercial use; it's a workhorse. The skeg rudder design offers excellent protection and maneuverability, critical for commercial operations in varied conditions. The fundamental structure is sound, which is paramount for a vessel of this age and type.

Power comes from twin Detroit 8V71 Natural engines, a well-regarded and incredibly durable powerplant in the commercial marine sector. With 13,100 hours, these engines have seen significant use, but Detroits are known for their longevity if properly maintained. The total 460 hp provides reliable propulsion for its intended use. Crucially, the owner is including two running 'take out' spare engines, which is a significant value add, offering immediate redundancy or parts for future maintenance.

Interior layout is functional, featuring one head, and designed for passenger transport rather than luxury. Recent upgrades, particularly in 2016 and 2017, address critical areas: fuel tanks, plumbing, fire suppression (fire pump, FireBuoy, extinguishers, EPIRB), navigation electronics (GPS plotter, VHF radios), and safety gear (life floats, life ring). Mechanical upgrades include transmission rebuilds, heat exchanger service, hydraulic pump replacements, and shaft and rudder work. The recovered passenger benches and new bicycle transport rack also show attention to passenger comfort and utility.

This Marine Management vessel is not a turnkey luxury yacht; it's a working boat with a history and a future. Its value proposition lies in its proven commercial certification, robust construction, and the significant recent investments in its operational systems. A buyer should consider this vessel if they are looking for a reliable, commercially compliant platform for dive charters, ferry service, or similar passenger transport operations, and are prepared to address the remaining cosmetic and minor repair items.
