Seawind 1370 Sailboats for Sale

The 1370 was conceived as a couple's liveaboard and it shows throughout. The sail plan centers on a full-batten square-top main stowed in a boom pouch and a self-tacking jib on a Solent arrangement, with a screecher on a second furler — a configuration designed for shorthanded passage-making rather than racing. Performance from that package is creditable for a heavy cruising cat: reaching speeds in the mid-to-high single digits are achievable in moderate breeze, and the upwind angles are reasonable for fixed-keel geometry. The twin helms are positioned outboard, adjacent to the hulls, with removable windows that give sightlines through the salon — a signature Seawind ergonomic detail that buyers tend to either appreciate immediately or grow to love after the first passage.

Layouts on the Used Market

Owner three-cabin layouts are the more commonly encountered configuration on the used market, though both arrangement options do appear. The port hull on most examples is dedicated to the owner's suite, built around a queen berth mounted athwartships at mid-hull — a sensible placement for passage comfort — with a full head and shower aft and a walk-in closet forward behind a watertight bulkhead. The starboard hull is configured for guests or crew, with a double berth aft, a head amidships, and a forward area that can be fitted out as an additional berth or used for stowage, giving the boat theoretical sleeping capacity well beyond what a cruising couple typically needs.

The salon is a galley-up arrangement with a U-shaped counter and opening trifold doors to the cockpit that, when raised and stowed, genuinely merge interior and exterior spaces. A navigation station to starboard and an L-shaped couch to port with a convertible table complete the main cabin. The cockpit itself is generously sized, with a full-width transom bench, a sink to starboard, and a grill position to port — a layout that Australian-heritage builders tend to get right.

Equipment and Common Upgrades

Boats coming off this platform are typically well-provisioned from the factory, and the used examples that circulate on the brokerage market tend to be loaded further still. Solar is commonly fitted — the design accommodates roof panel arrays naturally given the large coach roof and arch structure — and dinghy davits are a near-universal addition for bluewater-oriented owners.

Lithium battery banks appear frequently, either factory-fitted as an upgrade from the standard gel-cell specification or retrofitted by owners who want extended capacity at anchor. Radar, chartplotter, and autopilot are broadly present across the market. Watermakers are a common addition on boats that have been fitted out for extended cruising, as are freezers and washing machines — the kind of equipment that reflects the liveaboard use case the design was built to serve. Electric winches and inverters are often seen. Air conditioning appears on many examples, which is consistent with the boat's presence in warm-weather cruising grounds.

Asymmetric spinnakers and cockpit showers come up as owner additions rather than standard features. Hot water systems, while included in many configurations, are sometimes a later owner upgrade depending on specification level.

What to Inspect

Given the 1370's recent production history, osmotic blistering is not the concern it would be on an older hull, but the PVC foam-cored infused construction used throughout the hulls and decks warrants a careful survey regardless. Check all core areas — particularly around chainplates, deck hardware, and any penetrations — for any moisture ingress that might have begun through improperly bedded fittings. Vinylester resin throughout the laminate provides good blister resistance, but the survey should not be skipped.

The saildrive installations for the twin Yanmar diesels are a routine inspection point on any catamaran of this era. Saildrives require periodic bellows inspection and replacement on a conservative schedule; confirm the service history, check bellows condition directly, and verify that the anodic protection is current. The 57 hp Yanmar engines offered as an upgrade option appear on a number of used examples in lieu of the standard 40 hp units, and either way, engine-hour logs and maintenance records are worth requesting.

The electrical system deserves attention proportional to how heavily it has been upgraded. Boats with aftermarket lithium installations should be inspected for proper battery management systems, appropriate fusing, and correct integration with the 24-volt house system. Solar installations should be checked for proper charge controller configuration and connection integrity. A thorough inspection of the electrical panel, wiring runs, and any added systems is particularly important on liveaboard-equipped cruising cats where owners have often added substantial loads over time.

The trifold cockpit doors and their hinge and locking hardware should be operated and inspected — they are a clever system but one that sees constant use and deserves attention to sealing condition. The boom pouch for mainsail stowage should be inspected for UV and abrasion wear if the boat has accumulated sea miles.

Availability and Buyer's Takeaway

Used examples appear across a broad geographic spread, with listings surfacing regularly in the United States, Australia, Turkey, Southeast Asia, and Vietnam — a distribution that reflects both the builder's manufacturing locations and the bluewater cruising routes that owners favor. The Mediterranean and Pacific are both represented. Supply is not abundant given the model's recent production start, but the secondary market is active enough that a patient buyer searching over several months should find options.

The 1370 is a strong choice for the cruising couple who wants a modern, well-built bluewater catamaran with a thoughtfully designed liveaboard layout and a sail plan manageable by two. Buyers should be realistic about pricing — this is not a bargain segment — and should budget for a thorough survey regardless of the boat's apparent condition and youth.

Pre-purchase checklist:

• Commission a full out-of-water survey with core moisture testing at all hardware penetrations
• Verify saildrive bellows condition and replacement history
• Request complete engine-hour logs and maintenance records for both Yanmars
• Inspect lithium battery installation (if fitted) for BMS integration and wiring quality
• Check solar charge controller configuration and all added electrical loads
• Operate trifold cockpit doors and inspect sealing hardware
• Confirm sail inventory condition and boom pouch integrity
• Review any warranty transferability with Seawind directly
