SEA SEÑORITA – 2004 OCEAN 57 SUPER SPORT

Meticulously Maintained • Extensively Updated • Caterpillar C18 Power
YES SHE HAS - (SEA-KEEPERS 5)

Sea Señorita is an exceptional example of the highly regarded Ocean 57 Super Sport, offering the performance, ride, and accommodations that have made this model such a desirable sportfishing platform.

What truly separates Sea Señorita from many boats of her vintage is the level of care she has received. Her current ownership has taken a proactive approach to maintenance, with significant investment made in the machinery, cooling systems, fuel system, electronics, air conditioning, running gear, and other critical onboard systems. Many of the costly items buyers are concerned about when evaluating a vessel of this size have already been addressed.

She is powered by twin Caterpillar C18 diesels with just over 3,000 hours, and a comprehensive 3,000-hour engine service has recently been completed. This was far more than routine fluid and filter maintenance. The work included replacement of the aftercoolers, new water pumps, new injectors, powder-coated valve covers, heat exchangers cleaned, cooling systems descaled with Barnacle Buster, complete fluid service, and additional fuel-system work. The engine fuel pumps have also been addressed, the fuel transfer pump has been replaced, and the Racor system has recently been serviced.

The replacement of the aftercoolers in particular represents a significant maintenance item already completed for the next owner.

Beyond the machinery, Sea Señorita has continued to receive meaningful upgrades throughout the vessel. Her electronics have been updated with Garmin equipment including radar, autopilot, and AIS, while an engine display was replaced in May 2025.

Recent improvements and maintenance include:

* Full Caterpillar C18 3,000-hour service
* Aftercoolers replaced
* New engine water pumps
* New injectors
* Heat exchangers cleaned
* Cooling systems descaled with Barnacle Buster
* Complete engine fluid service
* Engine fuel pumps addressed
* Fuel transfer pump replaced
* Recent Racor service
* Engines and generator serviced – June 2026
* New Garmin radar
* New Garmin autopilot
* New Garmin AIS – November 2025
* Engine display replaced – May 2025
* New refrigerator/freezers – January 2026
* Forward air-conditioning system replaced – August 2026
* Salon air-conditioning system replaced – May 2025
* Helm chairs refinished – June 2026
* New batteries – May 2026
* Bottom job completed – January 2026
* Running gear painted – January 2026
* Trim-tab actuators replaced
* Rudder packing replaced
* Shaft seals replaced with newer-style seals, with spares

The result is a 57 Ocean that reflects the kind of ownership buyers hope to find: consistent maintenance, thoughtful upgrades, and attention given not only to cosmetics, but to the mechanical and operating systems that matter most.

The Ocean 57 Super Sport has long been appreciated for combining serious offshore capability with the comfort and volume expected from a larger convertible. Sea Señorita builds on those qualities with an impressive maintenance history and a substantial list of recent improvements.

For the buyer searching for a quality 57 Ocean—and particularly one who understands the value of having major mechanical and systems work already completed—Sea Señorita deserves serious consideration.

She is a vessel that has been maintained to be used and enjoyed, not simply prepared for sale.

Sea Señorita is ready for her next owner and represents an outstanding opportunity in the 57 Ocean Super Sport market.
