Description

The 2004 Mainship 430 combines the comfort and livability of a motor yacht with the efficient, practical character of a true cruising trawler. Designed for extended stays aboard, she offers generous interior volume, excellent visibility, and the kind of thoughtful layout that makes long-distance cruising—and relaxing at the dock—equally enjoyable.


Her spacious salon provides an inviting gathering area with abundant natural light and excellent sightlines. Below deck, the well-appointed accommodations provide comfortable sleeping quarters for family and guests, while the galley is designed for practical meal preparation during extended time aboard.


Outside, the 430's expansive flybridge is one of her defining features. It provides an ideal setting for entertaining, relaxing, and enjoying panoramic views underway. The aft deck adds another versatile outdoor living space, creating a natural flow between the interior and exterior areas.

With her substantial fuel capacity, comfortable cruising characteristics, and capable semi-displacement hull, the Mainship 430 is well suited to coastal cruising, extended voyages, and seasonal living aboard. Her twin diesel configuration provides dependable power and maneuverability, while her relatively modest draft opens up a wide range of cruising destinations.
