All handrails are of double-rung design for safety, and are welded and beautifully polished.

Window frames are powder coated aluminum and show no signs of corrosion.

Deck hardware is sturdy and high-quality stainless steel with no corrosion and little evidence of staining.

Boarding astern is from a large swim platform though the transom door. The covered cockpit is large enough for several deck chairs. The sturdily-built wide sliding aft cabin door provides entry to the full-beam saloon, which is much larger than would be expected in a boat this size. The galley is forward starboard and features granite countertops. There's space for a comfortable reclining chair aft starboard. To port is the convertible L-shaped dinette, storage cabinet and entertainment center. Just forward and down is the day head -- complete with shower capability. A curtain enclosure allows the entire port side of the salon to be converted to a private suite (including private head) for guests.

The pilothouse is just two steps up from the salon and is not isolated as on many other pilothouse models. The L-shaped dinette allows three or four guests to enjoy the pilothouse while underway. The dinette converts to a single pilot berth. The helm station is to starboard, and features a sliding helm seat with a moveable bolster for leaning if desired. Forward visibility from the helm station is excellent, and because of the low pilothouse design it's possible to view the aft quarters directly from the helm seat also (unusual in a pilothouse model). Sliding pilothouse doors port and starboard allow easy access to the dock, the foredeck or to the flybridge.

Footwells with high bulwarks provide security when exiting the pilothouse, and the wide, full-size steps to the flybridge make access safe and easy. There are no vertical ladders on this boat!

The master cabin has a queen bed, hanging lockers port and starboard, six storage drawers, two storage cabinets, and separate head and shower compartments.

The flybridge has a pedestal helm seat and L-shaped settee. As with the entire exterior of the boat, the design of the flybridge is uncluttered and obviously intended to be simple to maintain and easy to clean.

Cabin heat is provided by a Webasto diesel-fired forced air furnace. And for fresh air this boat has nine opening windows (including an opening windshield window), five opening stainless steel portlights, and two overhead hatches.

Broker's Comments

This Mariner 37 Seville Pilothouse Trawler appears as nearly new. The gleaming white gel coat shines and the stainless steel rails and fittings are almost entirely unblemished. The beautiful interior is equally clean and well-maintained.

This boat gives the impression of being much larger than its size implies with a very roomy interior and a design that includes a full-beam saloon, a day head, separate master head and shower compartments, and an extended pilothouse that actually serves as a comfortable living area in addition to its piloting function.

The quality of materials and construction are evident with teak and holly floors, beautiful teak joinery, heavy fittings and rails, sturdy deck sections, and thick engine compartment sound insulation.

You'd be hard-pressed to fit more boat into a 40' slip -- and with her Cummins QSB 5.9 425 hp engine she performs frugally at 7 or 8 knots, and has the power to get up and go when needed.

While Mariner Yachts (and especially the Seville line) are relatively new to the west coast, there is already a sizeable number of Mariner 37's in the Puget Sound fleet. These boats always get attention and admiration. Compare this boat to a Nordic Tug 37 or 39, or to an American Tug 34, 365, or 395. You'll find the Mariner is roomier, has a more finely-crafted interior, and is built to a very high standard -- at a much more economical price.
