This is a substantial midsize voyager rather than a lightweight weekender. Its high freeboard is a deliberate trade-off: raising the cabin sole creates more floor area and interior volume than a lower-sided 40-footer could offer.
Design and Construction
Judel/Vrolijk’s lines give the Najad 400/405 a handsome profile, with a fixed windshield and a low cockpit coaming rising above a long cabin trunk. The overall effect is more sheltered ocean cruiser than racer-cruiser.
The design carries a displacement of 26,896 pounds on a 34-foot-3-inch waterline. Its 8,818 pounds of lead ballast produces a ballast-displacement ratio near 33 percent. Beam is 12 feet 7 inches, and draft is 6 feet 6 inches.
The hull is solid fiberglass with a solid core, while the lead ballast is carried on a fin keel. The rudder is skeg-hung—a conservative, seaworthy arrangement suited to the boat’s offshore brief.
Najad built these yachts to order, allowing some customization within the three available interior plans. The trade-offs made to gain living space are clear: there is no voluminous lazarette, and the forecabin is small and accessible only through a flush hatch on the foredeck. That space was instead used to make the saloon and aft cabins genuinely roomy for a boat of this length.
Rig and Handling
The fractional sloop rig has a mast height of about 57 feet above the waterline and carries close to 850 square feet of sail. A period review calculated the sail-area-to-displacement ratio at 14.13 on the standard dimensions.
That is a modest figure for the boat’s displacement, but the same review noted that the 53-horsepower Yanmar could provide speed and help with pointing in light air. The chainplates sit smack in the middle of the side decks, providing a straightforward, easily inspected lead for the shrouds. When not in use, the spinnaker pole is stored on the mast, leaving the foredeck clear.
As might be expected on a 40-foot center-cockpit boat, the cockpit is on the small side. It has one deep locker, which the original reviewer considered awkward to use efficiently, supplemented by small saddlebag lockers in the quarters.
Accommodations
The standard layout has a centerline double berth aft and a single head accessible from the saloon. Buyers could instead choose outboard single berths aft or two aft staterooms. In the two-stateroom arrangement, however, one cabin can be reached only by walking through the other.
Forward of the cockpit, the galley runs along the passageway. The sinks leave no room for dish stowage on either side, one of the quirks of a layout designed to maximize living volume.
In the main saloon, buyers could specify either a starboard settee berth or Streisand chairs. Overall, the boat provides a great deal of interior space for 40 feet. The reviewer concluded that it would make a great cruising vessel for a couple with two children, with three layouts allowing a family to tailor privacy and berthing to its own needs.
Storage and Layout Compromises
The main points for a buyer to consider stem from the layout rather than a tendency toward failures. The small forecabin and lack of a voluminous lazarette restrict dedicated storage for ground tackle and storm gear. The awkward shape of the deep cockpit locker also means that provisioning stowage requires some planning.
The walk-through access in the two-aft-stateroom layout is a compromise in privacy rather than a defect, but buyers should understand it before purchase.
Refits and Ownership
Because Najad built these boats to order, individual examples vary in their factory-fitted equipment and subsequent owner refits. A used 400/405 may therefore already have upgrades specified by its first owner.
The high freeboard and center-cockpit layout suit a long-term cruising owner who values a protected helm and enclosed cabin trunk more than an expansive aft deck or racing ergonomics.
The Verdict
The Najad 400/405 is a carefully volume-engineered 40-foot center-cockpit cruiser from Judel/Vrolijk’s Najad generation. It trades forecabin and lazarette space for a roomy interior, three customizable layouts, and a sheltered offshore profile.
It is a bluewater candidate for a couple with children, combining a conservative skeg-hung rudder and fin keel with moderate sail power backed by a useful Yanmar. Its cockpit is small, but well protected.
