Sunline — a 2007 Custom Marquis 55LS located in Edgewater, Maryland, for sale by broker. Responses to inquiries may come from a broker who is representing the owner as a fiduciary.
Meet SUNLINE, a 2007 Marquis 55 LS that has been transformed through an extensive series of mechanical, interior and exterior upgrades. With three staterooms, a full-beam master suite , SUNLINE delivers the space and amenities expected of a much larger motor yacht while maintaining a comfortable, highly functional layout for cruising and entertaining. The enclosed, climate-controlled flybridge is a standout feature, offering panoramic visibility along with a wet bar, electric grill, ice maker and refrigerator. Below, the main-deck salon and galley have been refreshed with new hardwood flooring, granite countertops, updated cabinetry, new appliances, sinks and faucets, new window treatments and wood-trimmed walls and ceilings. New mattresses, updated heads and plumbing, LED lighting and refreshed exterior cushions further elevate the onboard experience. SUNLINE’s upgrades extend well beyond cosmetics. Recent work includes a comprehensive overhaul of the twin 715 HP Volvo D12 diesels, generator overhaul, new bow and stern thrusters, five new MarinAire HVAC units, all new batteries and a new power inverter. Bottom paint and zincs were completed in 2024, the props were balanced, and the engine room was cleaned and repainted. A Kohler 23 kW generator, TNT hydraulic swim platform, underwater lights, Maxwell 3500 windlass, Raymarine navigation electronics and Simrad autopilot round out an impressive equipment list. SUNLINE offers a fresh opportunity to step into a substantially updated Marquis 55 LS with the space, systems and amenities to make every trip memorable.
