Description
The Mariner Seville 37 is a well-built coastal trawler designed for couples, offering exceptional interior space for its size, robust, comfortable handling in rough and choppy seas, and excellent fuel efficiency at displacement speeds. It features a warm, teak-rich interior, a low-profile pilothouse, a large, covered aft deck, and an optional second head, making it ideal for extended cruising or the Great Loop.
Performance: Known for handling heavy weather with a solid, comfortable ride, featuring a full keel with a protected propeller/rudder.
With her pilot house doors to port and starboard, going through the locks on the Great Loop (and there are many) will be as easy as reaching out the door to hang lines on lock bollards instead of standing in the rain!! This is a massive "quality of life" win. In the Great Loop locks, being able to step out instantly to either side to grab a line or fender keeps the stress levels low, especially if you’re short-handed.
Full Keel & Protected Running Gear: This is your insurance policy. The Loop involves shallow river stretches and debris; having a protected prop and rudder means a minor touch-on-bottom doesn't turn into an expensive tow and repair. Low Profile: The "low-profile pilothouse" isn't just about looks. It helps you clear the fixed bridges (like the 19.1-foot hurdle in Chicago) without having to dismantle half the boat. By dropping the mast (reported to be very easy) her air draft is reported to be 14’3”
In addition to the equipment list included in the listing, here are some recent updates:
Sept. 2024 new cushions in salon, helm station and on fly bridge. In the interior of boat all the sitting areas have been redone. On the fly bridge, the seating areas have all been updated. Neither captain’s chairs were changed because they still look good.
