Brief Summary

Cobalt Boats says their 373 cruiser, the largest in the company’s stable, is “beauty matching brawn bow to stern.” OK, marketing folks have never been known for understatement, but this is an express cruiser, one of a class of yacht often criticized for ho-hum engineering and construction. Typically, express boats are used in sheltered waters under friendly summer skies – they don’t have to be built like icebreakers, and most are not. But is Cobalt different? Have the folks there gone over the top in hype, or is this boat really something special under its sleek fiberglass skin?

Captain's Report

Cobalt 373
Standard power is a pair of MerCruiser 496 Mag HOs spinning Bravo III drives. There are no optional engines, but Merc’s Axius joystick control with digital throttles and shifts (DTS) is available ($28,500); DTS on its own adds $5,183.

Built to Last

Few builders of express cruisers like the 373 stress their construction techniques; these boats are more about comfort and convenience than toughness. But Cobalt, located almost in the exact middle of the U.S., about as far from the sea as one can get, engineers their boats for open-water use, using top-quality materials and methods. Slice into the hull of a 373, and you’ll find not only fiberglass cloth, but Kevlar and carbon-fiber reinforcement, too. (Kevlar adds strength to a laminate; carbon fiber adds stiffness. They are both very expensive which is why most builders do not use these materials.)

Cobalt 373
The 373’s cockpit is designed for comfort: There’s seating for more people than you’ll probably want to bring aboard, and a table for feeding them. A cockpit grill ($1,566) is optional, as is a refrigerator or icemaker (either one, $1,931). A sunpad filler cushion adds $592, a sunpad on the foredeck, $1,597.

Cobalt quality starts on the outside: All accent stripes, waterlines and graphics are done in the gelcoat during lamination – no decals or tape or paint as you’ll find on many similar boats. A barrier coat behind the gelcoat prevents water absorption into the laminate; layers of fabric reinforcement are then hand-laid and rolled in vinylester resin, with coring – superlight but strong honeycomb material, not balsa or foam -- used where appropriate.

Cobalt 373
Cobalt will rig your 373 with a full array of Garmin electronics, including a 5208 chartplotter ($1,486) and fishfinder ($871). We’d want radar, too: either a 24” radome ($3,664) or 48” open array ($5,894) is optional.

The solid bottom is strengthened with Kevlar – Cobalt says it’s ¾” thick. The bottom is further reinforced with a full-length stringer system laid-up with carbon fiber to make it stiff and light. Finally, all structural bulkheads are vacuum-infused composites, again to maximize strength while minimizing weight. Cobalt is the only builder we know of which makes its bulkheads with this process. This is high-performance technology, utilized to built a truly first-rate family cruiser.

Cobalt 373
No surprises in the deck layout. The U-shaped lounge aft would be our dining area of choice in nice weather, and we’d add the cockpit grill and refrigerator to save trips down below.

But It’s Comfortable, Too

A rugged skeleton doesn’t mean the Cobalt 373 is rough to the touch. The boat is plushly appointed, with comfortable seating all around the cockpit, a large, stylish salon belowdecks and two staterooms – the twin-berth second cabin is maybe a little tight, but fine for kids and occasional guests. All furniture and upholstery is done in-house, using the same care in the details that Cobalt exhibits in the boat’s structure. Cobalt has built its reputation on yacht-quality fit-and-finish.

Cobalt 373
The walnut joinery in the salon is classy -- just like the wood you see in megayachts. The salon is roomy for a 37-footer, and the galley looks workable. The countertop is granite, there’s a microwave oven and an electric stove, an under-counter refrigerator, too. The settee is Ultrasuede, and converts to a double berth.
Cobalt 373
The queen berth in the master cabin uses a conventional coil-spring mattress. There is ample stowage in lockers, shelves for holding eyeglasses and a book at night. Hullside windows let in daylight. Note the room to port and starboard of the bed which is difficult to achieve in this size boat.
Cobalt 373
The guest cabin is adequate, and can be converted to a double with a filler cushion. The boat has two heads, both with showers.

Prices and Recommendation

The MSRP of the Cobalt 373 is $448,597 with the twin MerCruiser 496 Mag HOs. The boat is well-equipped, but we’d want a few options. Cobalt offers a diesel Kohler generator in place of the standard 7.3-kW (CO-safe) gas model ($2,215 upcharge). Take your pick.The standard boat comes with an arch but no enclosure, which adds $4,481. We prefer a hardtop, although it’s an $23,767 upgrade, including the enclosure. (Given the price of the boat, this adds just 5% to the cost, but we think it pays off with about 25% more utility for the boat.) A bow thruster is $7,571, oil-change system for engines and genset, $4,069, TV in the master cabin, $1,391. In all, a complete boat would cost us around $520,000 if we went for the Axius upgrade. But in any case, you’ll get a nice boat, a beauty on the surface and a beast underneath. It would be a boat we’d look at if we wanted a first-class express cruiser – in this size range.

Cobalt 373
These folks look too well-dressed to have been on a boat. Maybe they’re waiting for a launch to take them ashore to dinner. If we had a boat like the Cobalt 373, we’d eat on board. We like the creative shapes of the portlights on this boat -- something that is becoming a distinctive element of new Cobalts.
