Some boats simply check boxes. Others tell a story.

“Confluence” is the kind of boat that has already proven what it was built to do. This 2004 Mainship 400 Trawler has spent years cruising America’s waterways exactly as intended—comfortably, efficiently, and confidently. Designed with the Great Loop lifestyle in mind long before “Loop-ready” became a marketing phrase, the Mainship 400 remains one of the most respected and sought-after cruising platforms on the market today.

Powered by dependable twin Yanmar 240HP diesel engines, “Confluence” offers the handling confidence of twin screws combined with the fuel efficiency and owner-friendly systems that have made the Mainship 400 a favorite among experienced cruisers for decades. Whether navigating tight marinas, winding rivers, coastal waterways, or long ICW stretches, this boat delivers the kind of practical cruising experience that keeps owners on the water longer and with less stress.

What immediately separates the Mainship 400 from many other trawlers in this size range is the livability.

Wide walkaround side decks, molded stairs to the flybridge, an exceptionally usable cockpit, and excellent visibility from both helms make this boat feel safe and manageable underway. The lower helm—complete with nearby side deck access—is especially appreciated during poor weather, early morning passages, locks, and docking situations.

The fully enclosed flybridge effectively becomes a second salon and one of the most enjoyable areas aboard the boat. With expansive seating, excellent sightlines, and upgraded electronics, it’s easy to picture long cruising days followed by quiet evenings at anchor with friends and family.

Inside, “Confluence” delivers the warm, inviting feel that has made Mainship trawlers so popular with liveaboards and Loopers alike. Large windows bring in abundant natural light while the teak interior creates a timeless cruising atmosphere that feels comfortable the moment you step aboard.

The two-stateroom layout offers impressive accommodations for a boat in this size range. The forward master stateroom features an island queen berth and generous storage, while the guest cabin provides comfortable twin berths for additional guests or family. Combined with convertible salon seating, the layout easily supports extended cruising or seasonal living aboard.

Over the years, the boat has received numerous thoughtful upgrades focused on making life underway more comfortable and capable. Modern Raymarine electronics—including dual Axiom multifunction displays, radar, autopilot, AIS, cameras, and updated communication systems—bring this classic trawler fully into the modern cruising era.

Additional cruising upgrades such as inverter power, upgraded anchoring equipment, fuel flow monitoring, WiFi capability, and other owner-focused improvements make “Confluence” particularly well-equipped for long-distance cruising and extended time away from the dock.

Just as importantly, the current owners have invested heavily in mechanical maintenance and preventative service. In 2024 alone, nearly $20,000 was spent at Lamb’s Yacht Center addressing major service items and system upgrades.

Recent work includes:

• Full engine and transmission service
• New motor mounts and engine alignment
• Cooling system service
• Oil cooler replacement
• Alternator rebuild/service
• Generator maintenance
• Bilge pump replacement
• Plumbing and sanitation system repairs
• Electrical troubleshooting and repairs
• Anchor washdown installation
• Valve adjustments and preventative maintenance

This level of documented care matters. These are the expensive and often overlooked projects that can quickly add up for a new owner—and many of them have already been addressed aboard “Confluence.”

The Mainship 400 has earned its reputation honestly. It is a boat designed by cruisers for cruisers—efficient to operate, easy to maintain, comfortable to live aboard, and capable of taking its owners almost anywhere they want to go.

Whether your plans include America’s Great Loop, the Great Lakes, the Chesapeake, the Bahamas, or simply enjoying weekends aboard at your favorite marina, “Confluence” offers an outstanding opportunity to step aboard a proven cruising platform that is already equipped for adventure.
