1999 Navigator 5300 | 57ft

Sea Urchin is a remarkably well-kept 1999 Navigator 5300 Pilothouse Motoryacht, extensively refit and thoughtfully modernized for Pacific Northwest cruising. Built in the U.S. they are prized for her big-boat volume, secure pilothouse, generous salon/galley-up layout, and true three-stateroom accommodations. 

Sea Urchin stands well apart thanks to a purposeful modernization focused on reliability, comfort, and energy independence. Major recent work includes a Victron lithium power conversion (2023) with 800 Ah lithium bank, new Garmin chartplotters (2025) at both helms plus a third in the tender, new turbos (2025), Muir windlass and Vulcan anchor (2023), re-carpeted and soundproofed interior (2024), and a rebuilt/expanded watermaker (2023). 

Her Volvo TAMD 63s (370 hp each) are proven workhorses, regularly maintained with updated heat exchangers and serviced running gear. Naiad stabilizers, a Wesmar bow thruster, Glendinning synchronizer, and thoughtful helm ergonomics make Sea Urchin an easy, comfortable yacht for couples or families. 

If your short list includes secure pilothouse cruising with real home-style livability and thoughtful electrical work already done, this Navigator 5300 deserves a priority viewing.
