I met-up with Steve Smith, founder and president of Mariner Yachts International, on Kent Island, Md., to review the Mariner 40 sedan trawler. With her Chinese-built semi-displacement hull and deck, and much of her states-side fitting out and commissioning, this boat is truly an international production.

Steve explained that Mariner's hull is time-tested and proven, having been used in more than a dozen different trawlers over the last few decades. (He didn't say which ones.) Her classic deck layout incorporates certain features that any offshore cruiser will appreciate—the covered side-decks and high bulwarks, for example, along with the stainless steel hand rails that add yet another layer of security. Plenty of scuppers should keep the sidedecks clear of standing water.

The covered aft deck has a ladder leading to the sundeck and upper helm station. Up top, the Mariner 40 has plenty of deck space for dinghy storage or sunbathing. Below the waterline, a substantial keel protects her prop and helps the 40 track better in rough water. Her all-American power plant is a six-cylinder 425-hp Cummins with efficient electronic fuel injection and gobs of torque. (The newest version of this same engine is rated at 480 hp).

The cabin is spacious and practical, with daily activities on one level: driving, cooking, eating, lounging and line handling. The staterooms and head are down below. Beginning aft in the main cabin, a cabinet to port is pre-plumbed and wired for an optional washer/dryer unit. Just forward of that is an L-shaped settee and high/low table facing aft. The settee converts to a double bunk. The galley is forward of the settee, with the refrigerator and freezer located to starboard just aft of the lower helm station (this unusual layout puts items like drinks and ice within easy access of the dinette, aft deck and lower helm station). The galley is fairly small but included a double sink, granite counter tops, a two-burner electric stove and a convection/microwave oven.

The master stateroom is forward (below) with a queen-size island bed. The guest stateroom, to port, has over/under bunks. The head has a separate stall shower.

Underway the Mariner performed well. Engine noise was well muffled and the ride was smooth and comfortable. At six knots, we were burning 1.6 gallons per hour at 1150 rpm. At a fast cruise of 2750 rpm, we burned just over 15 gph, making 13.4 knots. Wide open, we reached 16 knots, burning 21 gph. While she is equipped with a bow thruster, I found her low-speed maneuverability to be excellent without it.

The Mariner 40 is a classic sedan trawler with modern equipment and amenities. Her saloon layout is unique but customizable to suit your needs. With her efficient and powerful engine and her reasonable price, she should appeal to serious cruisers who want to put miles under her keel.
