1996 Mainship 37 Motor Yacht

League City, Texas



You won't believe how much space has been packed into this 37 foot Motor Yacht! 

The Mainship's unique design opens up the interior space, which makes it feel very spacious. With a generous galley, open salon and both cabins featuring heads with separate showers, this boat has all the comforts of a much larger vessel.

On the exterior, there's great visibility and plenty of seating. A walk through in the flybridge provides direct access to the foredeck so that docking and anchoring are a snap. The covered aft deck with wet bar just adds more space to relax in and entertain family and friends.

"ONMYTAB" is powered by twin very economical Yanmar 230hp diesel engines. Her generator was replaced in 2017 and has very low hours. She also received updated electronics in 2016.

It's hard to find a diesel powered aft cabin motor yacht in this price range, so why settle for a gas powered motor yacht.

Offers considered!
