Design and Construction
The 373 blends traditional construction with more modern design. Its hand-laid GRP hull uses Najad’s solid layup, while the Divinycell foam-sandwich deck helps manage weight.
Below the waterline, the boat has a lead fin keel, offered with two draft options, and a skeg-mounted, partially balanced rudder. Many offshore sailors value the skeg-hung rudder for its added mechanical protection. In the standard configuration, draft is recorded at 6.23 feet. Ballast is 6,834 pounds against a displacement of 18,298 pounds.
With a ballast-to-displacement ratio of nearly 37 percent and a moderate sail-area-to-displacement ratio of about 16, the design combines relatively deep ballast with a measured rig to remain composed under load.
Rig and Handling
For a cruising design, the 373 points well and tacks predictably under main and genoa. Hull speed is around 7.5 to 7.6 knots. In mixed seas, the boat has a steady, confidence-inspiring motion rather than a tendency to skitter or surf.
The moderate displacement and Judel/Vrolijk hull form help it carry momentum through short, choppy seas. Its skeg-supported rudder also contributes to predictable handling, providing a protected blade that tracks without drama as the breeze builds.
Accommodations and Machinery
The center-cockpit arrangement makes room for a private aft cabin. Forward of the companionway, the interior is organized around a full saloon with long settees, a practical navigation station, and a forward V-berth. The finish is usually teak joinery with solid furniture, and many specifications list headroom at about 6.2 feet—respectable for a 37-footer.
The engine sits beneath the cockpit sole, keeping the machinery out of the living spaces and providing straightforward access. For a cruising couple or small family, the layout balances aft-cabin privacy with a sociable saloon.
Known Issues
Standing rigging and its fittings age on a normal schedule. Owners report replacement cycles of typically 15 to 20 years, depending on use, so a boat from this era is likely due or overdue for a rig overhaul.
The Divinycell sandwich deck can suffer water ingress or core delamination where poorly bedded hardware and chainplates penetrate it. Older examples may also have tired engine installations or transmission components, particularly when service records are incomplete. The Yanmar diesel beneath the cockpit sole is subject to the same age-related wear as any plant dating from around 1999.
Electronics and wiring are often dated and benefit from modernisation. Wear in the propeller, shaft, and cutlass bearing has also led many owners to install newer, more efficient propeller designs during refits.
Refits and Ownership
Compared with engines installed beneath companionway stairs, the engine’s position under the cockpit sole makes routine servicing simpler. The main wear points are familiar ones for any long-owned cruising boat: standing rigging, deck-hardware bedding, the drivetrain, and electrical systems.
A buyer or owner can plan a refit around these known items without surprises. Structural shell work is rarely the issue because of the solid-hull construction; soft spots are more likely to occur in the cored deck, while age-related wear also affects the running gear.
The Verdict
The Najad 373 is a considered answer to the comfortable, go-anywhere cruising brief. It combines a Judel/Vrolijk hull with a traditionally built Swedish deck, a protected rudder, and a center-cockpit interior that favors privacy and seakeeping over outright speed.
It behaves reassuringly when the weather turns, and its main weaknesses are ordinary consequences of age rather than fundamental design flaws.
Pros
- Steady, confidence-inspiring motion in mixed seas, with good pointing ability for a cruiser
- Skeg-hung rudder and lead fin keel, with deep ballast and added offshore protection
- Straightforward engine access beneath the cockpit sole
- Solid, hand-laid hull construction
- Private aft cabin, teak joinery, and a practical navigation station
Cons
- Risk of deck-core delamination around chainplates and deck hardware
- Standing rigging and drivetrain likely to need overhaul on most examples because of age
- Dated electronics and wiring that may require modernisation
