Navigator 5300

Accommodations

The 5300’s interior feels more like a coastal home than a yacht of her size. Three private staterooms sleep six in comfort, with two heads and separate showers. The full-beam master lies amidships with an island berth, generous lockers, and ensuite head upgraded to a Masterflush system (2022).

The lithium bank powers the bow thruster, significantly extending capacity for anchoring, heating, and galley use without generator dependency. A Glendinning Cablemaster simplifies shore-power handling, while LED lighting throughout lowers consumption.

Mechanical Systems

Sea Urchin is powered by twin Volvo TAMD 63 diesels (370 hp each)—known for their reliability and smooth performance. The port transmission was replaced (2023), and both turbos are new (2025). Cooling systems were pressure-tested and cleaned, and all heat exchangers serviced. A Kohler diesel generator provides auxiliary power when required. Naiad stabilizers and a Glendinning synchronizer enhance comfort and efficiency, while a Tides dripless shaft seal system keeps bilges dry.
