The Standfast 40 is a quintessential representative of the "Golden Age" of Dutch yacht building, emerging from the Breskens yard of Frans Maas during the peak of the International Offshore Rule (IOR) era. Following the sensational overall victory of Frans Maas’s own design in the 1975 Fastnet Race, the Standfast 40 was developed as a high-performance production evolution of that championship-winning hull. These vessels are recognized globally for their exceptional structural integrity and the unmistakable aesthetic of Dutch naval architecture from the late 1970s and early 1980s. Unlike many of its contemporary production rivals that prioritized interior volume, the Standfast 40 was engineered first for the sea, featuring a deep-chested hull, significant tumblehome, and a powerful masthead rig designed to claw to windward in the demanding conditions of the North Sea.

Sailing Performance & Handling
The Standfast 40 is widely regarded as a "sailor’s boat," characterized by its formidable upwind ability and a remarkably stable motion in a seaway. Because it was designed under the IOR, the hull features a relatively narrow entry and a pronounced beam carried amidships with significant tumblehome, which provides a high degree of initial stability when the boat is pressed. While modern designs favor wide transoms and flat aft sections for planing, the Standfast 40 utilizes a deep, traditional bilge and a heavy lead keel that allows it to track with precision even in gusty conditions.
Under sail, the boat feels powerful and deliberate. It typically carries a large, overlapping genoa, which serves as the primary engine. In light air, the substantial displacement requires a dedicated sail plan to keep moving, but once the breeze reaches 12–15 knots, the boat finds its stride. Owners and testers from the era often noted that the Standfast 40 "stiffens up" as it heels, finding a sweet spot that minimizes leeway. The rudder configuration—usually a deep spade or skeg-hung depending on the specific build year—provides authoritative control, though the IOR-influenced hull shape can become lively when running deep downwind in heavy following seas, requiring an active hand on the wheel.
Interior Comfort & Variations
The interior of the Standfast 40 reflects a commitment to traditional craftsmanship that has become increasingly rare. Most hulls were finished in high-grade teak or mahogany, with a focus on functional offshore ergonomics rather than "dock-appeal." The layout typically centers on a deep, secure U-shaped galley to port and a proper forward-facing navigation station to starboard—both designed for use while the vessel is at an angle of heel.
The salon usually features a U-shaped settee and a straight settee opposite, often accompanied by pilot berths situated high and outboard. These pilot berths were a staple of the era’s racing heritage, providing the most stable place to sleep during offshore passages. The master cabin is traditionally located forward, featuring a V-berth with ample storage, while the aft sections often house a dedicated quarter berth or a small aft cabin, depending on whether the owner opted for the "Cruising" or "Racing" internal configuration.
Sibling models built on similar design philosophies include the slightly smaller Standfast 36 and the significantly larger Standfast 43. While the 43 offered more luxury and a larger aft cabin, the 40 is often cited by purists as the most balanced iteration of the Maas design language, offering the best ratio of performance to manageable size for a shorthanded crew.
Known Issues & Buyer’s Checklist
Purchasing a Standfast 40 today requires a discerning eye for the aging of 1970s and 80s composite construction. Prospective buyers should prioritize a professional survey of the deck; like many yachts of this period, Standfast utilized a balsa or foam core for stiffness, which can suffer from delamination if deck hardware (stanchions, tracks, and cleats) has not been periodically re-bedded.
The hull itself is famously robust, but older Standfast models are known to be susceptible to osmotic blistering if they have not undergone an epoxy treatment in their later life. Furthermore, the masthead rig exerts significant tension on the chainplates and the mast step. Inspecting the longitudinal stringers and the grid system for any signs of movement or stress cracking is essential, especially on boats that have been campaigned heavily in offshore races. Lastly, the original engines were often Volvo Penta units that may be nearing the end of their service life; buyers should check for the availability of parts or factor in the cost of a modern repower.
Community & Resources
The legacy of the Standfast 40 is preserved by a dedicated group of owners, primarily centered in Northern Europe. The most prominent hub for technical data and history is the Standfast Owners Club, which serves as a repository for original Maas drawings and technical specifications that are no longer available from a commercial builder. Owners often share insights on localized Dutch forums and international cruising communities, reflecting the boat's status as a respected "classic" in the yachting world.
The Verdict
The Standfast 40 remains a prestigious choice for the offshore sailor who values build quality and windward performance over modern interior volume. It is a vessel built to endure, offering a level of security in heavy weather that few modern "light-displacement" cruisers can match.
Pros:
- Exceptional upwind performance and heavy-weather stability.
- High-quality Dutch construction with superior teak joinery.
- Timeless, elegant lines that command respect in any marina.
- Proven offshore pedigree, including a lineage tied to Fastnet success.
Cons:
- Requires a large crew or powerful winches to handle the massive overlapping genoas.
- Interior volume is lower than modern 40-footers due to the IOR hull shape.
- Maintenance of the sandwich deck and older rigging can be costly.
- The deep draft may limit access to shallower cruising grounds or canals.
