The Mainship 430 Trawler is a combination of classic design, innovative engineering and modern manufacturing methods. Since its inception 20 years ago, Mainship has produced thousands of boats, mostly in the trawler family. The focus has been and continues to be, in building high-quality, low maintenance diesel cruisers that are comfortable and affordable. Amazon is a beautiful example of the 430 model!

The 43 Trawler offers many great features that will optimize the cruising experience. Starting with the exterior, from the expansive flybridge, captains have an unobstructed view to all points. In the upper helm, both overhead and console space have been dedicated to electronic needs. Aft of the standard radar mast, are molded steps with diamond, non-skid leading to the aft deck which is large enough to store a tender. Sturdy aluminum rails offer excellent handholds and the cockpit is lowered for safer and easier entry to the full-size swim platform that includes a convenient swim ladder and freshwater shower. Heading to the integrated bow pulpit is safe for everyone with the wide decks and high bulwarks of the 43. The split anchor well will handle plenty of rode and an extra Danforth and includes an anchor washdown. Fore and aft shorepower outlets allow for choice of docking. The port and starboard cabin doors make short-handing a snap as well.

Moving to the interior, a fully instrumented lower helm allows the captain to comfortably operate the vessel during inclement weather. Counter space is usually at a premium on a boat of this size, but the galley on the 43 Trawler is a chef's paradise with plenty of Corian-covered counters, an oversize sink, a three-burner range, a microwave - convection oven, a refrigerator and loads of storage. All this is on the same level as the salon and has its own deck ac
