Hull Design and Construction
The 375 is built around a philosophy of speed through efficiency rather than brute power. A long waterline, low wetted surface, ample sections aft, and a relatively high-aspect keel and rudder define her underbody, while above the waterline, near-plumb ends, low freeboard, an open transom, and a generous beam give the hull its purposeful, contemporary look. The construction is thorough: a sandwich of E-glass and vinylester resin, foam core below the waterline and balsa core above, with vinylester chosen because it resists osmosis and bonds more thoroughly than polyester. Hull rigidity comes from a complex framework of foam stringers and floor beams, and major hardware above deck is tapped into aluminum plates laminated into the composite part — a sound solution provided fittings are kept properly bedded.
Rig and Sail Plan
The 375's sail plan is mainsail driven, with a fractional headsail set up on a curved track for self-tacking. Cruising World's Boat of the Year panel tested this arrangement off Annapolis and found it more successfully executed than on other boats they had seen — BOTY judge Beth Leonard specifically noted that the self-tacking jib actually set, a qualification that damns many rivals. In practice, having both sheets led to the cabin top means you must leave the wheel when trimming, so singlehanders bound for open water will want an autopilot factored into the build spec. An optional Dutchman boom brake made for effortless jibing, all hands-free. In-mast furling and a genoa are also available if the owner prefers a more traditional headsail arrangement.
Sailing Performance
On the water, the 375's performance impressed two separate test teams sailing under different conditions. In 7 to 8 knots of breeze, the boat pointed well, some 34–35 degrees off the apparent wind and tacked easily and swiftly through less than 80 degrees. The Cruising World panel, sailing in 6 to 8 knots on the Severn River, posted boat speeds of 5.3 knots and tacked through 85 degrees, calling it a boat that made you feel you could slip out of the dock and tack singlehandedly through the mooring field all afternoon under perfect control. As wind built toward 10 to 12 knots, the Sail test team started logging speeds closer to 6.5 knots on a reach. Steering on both single- and twin-helm versions was described as light, positive, and nicely balanced, and the single helm was characterized as butter smooth and responded convincingly. Under power, a deep rudder and short keel let you spin her around quickly and effortlessly, with the saildrive caveat that there's a short pause before the prop wash reaches the rudder.
Accommodations
Below, the 375 offers one or two aft cabins with an aft-facing or central chart table, giving owners meaningful flexibility. The saloon is light and open, with good handholds overhead and outboard lending a feeling of security under way. Ventilation is handled by two overhead hatches opening opposite ways and long portlights that open outwards so they can be safely left ajar in the rain. The galley is well equipped: twin sinks, a dual top/front entry fridge, and a two-burner gas range with oven are standard, with Corian countertops available as an option. The forecabin has a large V-berth and plenty of floor space, with headroom a few inches greater due to a dropped floor. The aft cabins share identical dimensions in both layout variants, though cockpit locker moldings restrict the clearance above the berths. The fully molded head includes a separate shower stall with a seat and partition door. One noted limitation: the holding tank is a bit small, and all the space beneath the forward berth is taken by the freshwater tank, leaving no underberth storage forward.
Known Issues and Build Quality
Both test teams flagged areas where build quality fell short of the 375's otherwise strong impression. The Cruising World panel found bare electrical wiring that had been glassed over, and an excess length of live wiring simply coiled up and dropped into the boat, with gelcoat later sprayed over it. They also found unsealed plywood edges in the galley that could cause swollen locker boards. On deck, the bow roller is offset some 25 degrees from the boat's centerline, which is not ideal when the chain snatches in a choppy anchorage, and the same offset could make hauling the anchor in a blow more difficult. The narrow side decks — a consequence of the cabintop being extended out as far as possible to maximize interior volume — require care when moving forward. The open transom, while excellent for swimming and boarding, means a lack of a permanently fixed ladder can make reboarding difficult for a single-handed MOB recovery.
The Verdict
The Hanse 375 is a genuine dual-purpose boat in the best sense: fast and easy enough to satisfy shorthanded sailors, yet comfortable and practical enough to serve as a family cruiser. Judel/Vrolijk's hull delivers real sailing performance without demanding a skilled crew, and the self-tacking rig is one of the most honest implementations of that concept in a production boat of this era. The build corners that were cut — particularly in electrical installation — are worth a thorough pre-purchase survey, but the structural bones, laminate chemistry, and sailing character are all solidly on the boat's side.
Pros
- Long waterline and low wetted surface produce genuinely quick performance for a 37-foot cruiser
- Self-tacking jib works as advertised; praised independently by two separate test teams
- Light, positive steering on both single- and twin-helm configurations
- Vinylester/sandwich construction resists osmosis and provides good structural rigidity
- Flexible interior layouts with meaningful galley and ventilation provisions
Cons
- Electrical workmanship found wanting on tested hulls; a pre-purchase survey is essential
- Offset bow roller complicates anchoring in any kind of chop
- Narrow side decks require careful crew movement forward
- Small holding tank and no underberth stowage in the forecabin
- Open transom lacks a fixed boarding ladder, complicating solo MOB recovery
