This is a very well-maintained (by a former Air Force mechanic) 40' single-engine trawler that is fuel-efficient. It has all the extra bells and whistles such as bow and stern thrusters for easy docking, stern camera, kitchen outdoor kitchen on the upper deck, enclosed fly bridge with extra seating, swim platform, forward and aft shore power hook-ups, a tub/shower combo in the head, dinghy, and more!

Once you enter the large sliding door, you will notice the entire vessel’s interior is trimmed in high-gloss cherrywood and features a very well kept teak and holly sole. The layout consists of a large main salon with the well appointed galley to starboard and a sleeper sofa to port. The dining area is forward, to port, opposite the lower helm, which has an easy to bow access door. There are large opening windows, ensuring plenty of light and cross breeze if you desire. Below is the owners queen berth forward with hanging lockers and en-suite access to the head. The guest quarters are to port under the dinette’s sole and has twin berths. Ascending the wide formed steps to the enclosed flybridge, you will not only find the upper helm that has a comfortable captain’s chair, but a surprising amount of usable space for entertaining which can easily be done with the summer kitchen that includes a large grill.

This is a very maintained vessel that seems to have been very well cared for and updated as needed. Very short list of needed maintenance items that are not essential for the typical cruiser. The boat has been stored on the hard every non cruising season since new (both current and past owner has adopted this process on this vessel.) and all covers/eisenglass/canvas has been stored in doors during those periods. You can defiantly see that this boat has been maintained by a military mechanic for sure!
All personal belongings and some tools.
