Some boats are built for adventure. Safe Haven has already proven herself.
This beautifully maintained 2008 Mainship 400 is a rare Platinum Looper, having successfully completed America's Great Loop twice with her current owners. Thoughtfully outfitted for long-range cruising and continuously maintained, Safe Haven offers the comfort, efficiency, and confidence that have made the Mainship 400 one of the most respected cruising trawlers on the water.
Powered by a reliable single Yanmar 6LYA-STP 270 HP diesel with approximately 2,511 hours, she is designed for economical cruising without sacrificing capability. Electronic engine controls, a bow thruster, and Mainship's articulating rudder system make docking and close-quarters maneuvering remarkably easy-even for solo operators.
One of Safe Haven's standout features is her ability to cruise independently. Four 100-watt solar panels continuously charge both the house and engine-start batteries, allowing comfortable time at anchor with minimal reliance on the generator. Combined with an efficient single-engine drivetrain and thoughtfully designed accommodations, she is exceptionally well suited for extended cruising.
Recent mechanical updates include a new main engine exhaust (2025) and new generator exhaust (2026). She has also benefited from indoor winter storage, reflecting the level of care she has received throughout her ownership.
If you've been searching for a proven Great Loop cruiser that's ready to continue the journey, Safe Haven deserves your attention.
