Sea Boss is a beautifully maintained 2005 Sea Ray 500 Sedan Bridge that offers an exceptional combination of performance, comfort, and thoughtful upgrades—making her an outstanding choice for coastal cruising, extended stays aboard, or completing the Great Loop. With recent updates throughout (2024–2025), strong Cummins power, and a proven three-stateroom layout, Sea Boss represents an excellent value in today’s market for a 50-foot class motor yacht.
Powered by twin Cummins QSM11 660HP diesels and supported by a 13.5kW Onan generator, Sea Boss delivers confident performance with the ability to cruise comfortably in the low 20-knot range or slow cruise efficiently at displacement speeds. The current owners have focused heavily on reliability, comfort, and livability—resulting in a yacht that feels truly turnkey and ready for her next adventure.
One of the standout features of Sea Boss is her spacious flybridge, offering excellent visibility, comfortable seating, a wet bar, air conditioning, and ample room for entertaining. Few boats in this class offer such a usable upper helm area while still maintaining a practical interior layout below.
Inside, the salon is warm, open, and welcoming with plush Ultraleather seating, high-gloss cherry cabinetry, new smart TV, and bamboo blinds. Large windows provide abundant natural light, creating a bright and inviting space that feels more like a waterfront condo than a traditional motor yacht.
Forward and slightly elevated, the dinette overlooks a well-appointed galley, making it easy to stay connected with guests while preparing meals. The galley features new Summit drawer-style refrigerator and freezer units, a Kenyon cooktop, and a GE microwave/convection/air fryer combo, along with generous storage and counter space. A large utility/storage room beneath the galley adds exceptional practicality for long-term cruising.
Below deck, Sea Boss offers a three-stateroom, two-head layout that comfortably accommodates owners and guests:
Forward master stateroom with island queen berth, new mattress, private en-suite head with rebuilt stall shower, new TV, and excellent storage
VIP stateroom with new mattress and generous cabinetry
Guest stateroom with bunks and new mattresses
Both heads rebuilt with upgraded VacuFlush systems and updated sanitation lines
Mechanically, Sea Boss has benefited from significant recent service and preventative maintenance. Highlights include cutlass bearings, aftercooler and heat exchanger service, raw water hose replacements, rebuilt Reverso oil change system, SmartCraft screen replacement, and engine/generator fluid services. These updates provide confidence for buyers seeking a yacht that is ready to cruise without immediate projects.
Comfort systems are equally impressive, with four air conditioning units covering the salon, (2026) forward stateroom, mid stateroom, and flybridge. AGM batteries, a Glendinning 75’ shore power cord, freshwater filtration system, and flushed hot water tank further enhance onboard reliability and convenience.
Electronics include Raymarine Axiom multifunction displays, radar, autopilot, fishfinder, VHF with external speaker, depth sounder, Side-Power bow thruster, and an upgraded Fusion stereo system. Starlink is included, hardwired and mounted, making remote work and streaming easy from anywhere.
On deck, Sea Boss features fresh bottom paint, a new windlass motor, rebedded windshield, good-condition canvas and isinglass, a large swim platform, and included fenders and dock lines—further reinforcing her turnkey status.
Sea Boss is an excellent opportunity for buyers seeking a well-maintained, upgraded, and realistically priced 50-foot motor yacht with strong systems, comfortable accommodations, and proven Sea Ray build quality. With a motivated seller and extensive recent improvements, she deserves serious consideration.
