Seawind 1370 Review, Specs and Price for a Bluewater Couple's Cat

The Seawind catamaran that sold out before launch

Seawind has always marketed its boats to what it calls real sailors, and the Seawind 1370 is the clearest expression of that idea so far. Seawind's sales and marketing manager told SAIL the company took 90 orders before the first boat was launched in 2023, and by 2025 it was booking production out to 2028. Owners formed a WhatsApp community to compare upgrades before their boats even existed.

The awards confirmed the hype. SAIL named the 1370 one of its Top 10 Best Boats for 2025, and Cruising World's judges named it the 2025 Best Midsize Multihull, ahead of the new Lagoon 43 and the Vision 444 ES. Nearly two decades earlier, the Seawind 1160 had won Cruising World's multihull category, and many of the details that judges praised then are still on the 1370.

Seawind was founded by Australian Richard Ward, who began with beach cats in 1982 and launched his first cruising model, the 850, in 1991. In 2010 Seawind bought Corsair Marine and moved production to a large plant in Ho Chi Minh City, Vietnam, where the 1370 is built. Cruising World also notes a newer Seawind facility in Turkey.

Ward's concept, French hull modeling

Richard Ward drew the boat, but for the hull shape Seawind brought in The Yacht Design Collective, the French duo François Pérus and Romain Scolari, to model the hulls by computer for performance. The result has sharp reverse bows with a fine entry, hard chines that add volume to the cabins, and fully integrated mini keels with spade rudders instead of daggerboards.

Construction is vinylester infusion over PVC foam, reinforced with carbon and Kevlar, and the layup is lean. SAIL's preview gave a displacement of 24,250 lb, while its later review quoted about 27,000 lb, presumably with gear aboard. Either way the 1370 is light for a 45 foot fixed-keel cruising cat, which is why it sails so well. The aluminum mast is set farther aft than usual to reduce pitching, which lengthens the foredeck and shrinks the forward cockpit area.

Mini keels that still point to 38 degrees

The argument for daggerboards is pointing ability. The 1370's test results make a strong case that well-designed fixed keels can come close. SAIL sailed with the square-top main and self-tacker at 38 degrees apparent and held 6.4 knots, and Cruising World made about 6 knots at just under 40 degrees off the wind. With only a partially hoisted asymmetric and no main, SAIL still made 7.2 knots in 9.2 knots of true wind on a beam reach, 78 percent of wind speed, and 8.3 knots at 125 degrees in 12 knots of breeze. Cruising World hit close to 9 knots on a broad reach under spinnaker.

The standard sail plan is a solent arrangement of full-batten square-top main and self-tacking jib, about 1,248 sq ft together, plus a screecher on a furler. With both headsails furling, changing gears short-handed is easy, and all lines lead aft to the cockpit, where electric Harken winches are optional.

Twin protected helms and the trifold door

Every Seawind has the same helm philosophy, and the 1370 refines it. Twin Carbonautica wheels are mounted on the aft bulkheads of the cabinhouse, either side of the cockpit, protected by the hardtop above and the saloon ahead. Removable or drop-down windows in front of each wheel give a view through the saloon to the bows, overhead skylights show the main, and you can sit outboard on the coaming for a clear look at the jib telltales. The test boat had engine controls and 12 inch B&G plotters at both helms, which makes docking easy.

Between saloon and cockpit is Seawind's trademark trifold door, which folds up and stows under the hardtop using a winch, with carbon in the hinge to save weight. With it raised, the whole main deck is open. The cockpit has a full-width transom bench with storage underneath, a sink to starboard and a stainless barbecue to port, and the helm seats are wide enough for two with backrests that flip to face aft.

Galley up, single level, and a real nav desk

Seawind's smaller models put the galley down in a hull. The 1370 borrows the galley-up arrangement of the larger Seawind 1600: a U-shaped counter in the aft starboard corner of the saloon with a sink facing aft, a three-burner stove (an induction cooktop on Cruising World's test boat) and oven, drawer refrigeration and a 130 liter upright fridge. A breakfast bar extends from the galley into the cockpit. Judges liked the many bracing points for cooking underway.

There are no steps between cockpit, saloon and galley, which makes moving around safer. A forward-facing nav desk in the starboard forward corner is a proper watchkeeping station, and SAIL praised Seawind for recognizing that ocean sailors need a dedicated place for ship's business. To port, an L-shaped settee surrounds a swiveling table that lowers to form a lounge or sea berth. Finishes in light ash and bird's-eye maple impressed both magazines.

An owner's hull to port and flexible space to starboard

The owner's suite fills the port hull, with a raised athwartships queen berth amidships, where motion is least, a vanity, a large head and shower aft that Cruising World called best in class, and a walk-in closet in the forepeak behind a watertight bulkhead. The starboard hull has a double aft, a head and shower amidships and a fore-and-aft berth forward, with the forepeak available for another berth or stowage, bringing sleeping space to nine.

Seawind's standard specification lists a 600 liter (about 158 gallon) fresh water tank, 520 liters (about 137 gallons) of fuel in two tanks, and holding tanks of 120 and 100 liters.

Yanmar 40s or 57s and a 24 volt electrical system

Standard power is twin 40 hp Yanmar saildrive diesels, with 57 hp Yanmars optional. SAIL's boat had the 57s with Gori folding propellers and found an easy cruise of 6.8 knots at 1,800 rpm. The 1370 runs on 24 volts, with four gel batteries standard and lithium optional. Seawind left out the generator on the test boat; with high-output alternators, four Mastervolt lithium batteries totaling 920 Ah and up to 1,930 watts of solar on the hardtop, SAIL's reviewer said you could run air conditioning all night and still wake up with power. Cruising World's boat carried 2.5 kW of solar.

Base price, the real price and ownership costs

Seawind's base price is $820,000. The Annapolis test boat, with the bigger engines, Corian counters, lithium, solar and electric winches, came to about $1.15 million, which SAIL said is right in the ballpark of its competitors. Expect most US boats to fall between those figures depending on options.

Annual costs of roughly $38,000 to $75,000 are realistic in the US, driven by a 24 ft 11 in beam slip, insurance for offshore cruising and normal maintenance. Skipping the generator and running a lithium and solar system lowers maintenance and fuel costs compared with many cats of this size.
