2003 Mainship 400, PartnerShip II                 For Sale $225,000 

Step inside and experience the comfort and classic beauty of the Mainship 400's updated interior. From the spacious salon to the well-appointed staterooms, every detail has been thoughtfully designed for both style and functionality. Imagine relaxing and entertaining in this inviting, luxurious space.

The vinyl headliner—often a common deterioration point on Mainships—has been completely replaced in the main salon and both cabins, ensuring years of worry-free enjoyment. New recessed LED puck lights provide a fresh, modern look, complemented by three small dimmable wall sconces with individual power switches that add a warm and inviting ambiance throughout the salon.

Custom retractable window shades offer flexible privacy control, while blackout drapes at the stern provide complete seclusion whether docked in a marina or anchored out. Two custom-made large cushioned chairs and a 30" TV mounted at the rear of the salon create a comfortable, family-room-style setting perfect for relaxing or entertaining.

The original carpeting in the hallway and cabins has been replaced with teak and holly vinyl flooring to reduce dust, dirt, and mold buildup. A custom-made teak table, newly upholstered bench, and a pair of custom stools provide a warm and welcoming dining area.

The electric stove has been professionally converted to propane following ABYC standards, allowing the chef to prepare meals without running the generator—ideal for quiet mornings at anchor. The large single-bowl sink and built-in dish soap dispenser offers ample space for meal prep and cleanup, while the under-counter trash compartment keeps waste neatly concealed. A built-in toaster oven sits neatly in an enclosure large enough to accommodate a small microwave if desired, offering flexibility for your preferred galley setup. The apartment-size 120v/12-volt refrigerator/freezer is compact yet efficient, providing ample storage for several days' worth of fresh food while conserving power.

Entertainment is provided by a Boss Audio AM/FM radio mounted on the fly-bridge, with additional speakers extending sound throughout the main salon. A 32" Smart TV and Bose 321 system with CD player, 2 wall mounted speakers and a bass speaker offer multiple options for music and viewing pleasure. Internet connectivity is seamlessly provided by a Peplink Max BR1 router coupled to a Generation 3 Starlink dish mounted on the radar mast. Powered by a 12-volt POE injector, there's no need to use the inverter, shore power, or generator. Using Starlink's Roam service, enjoy unlimited data whether underway, on the hook, or at the marina.

Explore the advanced systems that power the Mainship 400. The reliable Caterpillar 3126 engine, with only 1,375 hours, provides dependable propulsion for serious cruising, paired with state-of-the-art navigation equipment for confident operation. Rest assured knowing you have top-of-the-line technology and systems designed for reliability and ease of use.

The engine and transmission have been recently serviced, including oil, fuel, and filter changes, and a new raw water pump impeller. The engine has been thoroughly detailed, with attention to any corrosion and rust, and the heat exchanger, intercooler, and transmission cooler have been flushed to remove contamination.

The vessel also features dual switchable fuel pre-filters and an integrated fuel polishing system to ensure consistent, clean fuel delivery. A spare four-blade propeller with puller and wrench is included for uninterrupted operation. The engine room is exceptionally clean with dry sumps throughout, and proactive measures have been taken to eliminate the common rainwater intrusion issues often found in vessels of this vintage—ensuring long-term reliability and peace of mind.

A Mastervolt 2000-watt inverter supplies ample power for the included toaster oven or a small microwave, providing dependable off-grid electrical capability. The deep-cycle AGM batteries, replaced in December 2022, offer several more years of reliable service for confident cruising. The domestic water heater, plumbed directly to the engine’s cooling system, delivers hot water without the need to run the generator while at anchor—an efficient and thoughtful upgrade for extended stays.
