The Standfast Loper, designed by the legendary Frans Maas and built at the Standfast Yachts yard in Breskens, represents a high-water mark for 1970s Dutch series production. At approximately 8.25 meters (27 feet) in length, the Loper was conceived as a "Junior Standfast"—a vessel that distilled the offshore capabilities and rigorous build standards of the famous Standfast 40 into a more accessible, trailerable, or small-slip package. Introduced in 1977, the Loper was born from the International Offshore Rule (IOR) era, which is evident in its hull shape, featuring a moderate beam and a distinctive "pinched" stern. Unlike many mass-produced boats of its size from the same period, the Loper was constructed with a focus on longevity and structural stiffness, utilizing a solid fiberglass hull and often a lead keel, a premium feature for a 27-footer.

Sailing Performance & Handling
The Standfast Loper is widely regarded as a stiff, seaworthy performer that punches well above its weight class in heavy weather. With a ballast-to-displacement ratio often exceeding 40%, the boat exhibits remarkable stability. The lead fin keel provides a low center of gravity, allowing the Loper to carry its canvas longer than its lighter competitors. On the wind, the Loper tracks with precision, a characteristic attributed to the deep, high-aspect rudder and the balanced hull lines penned by Maas.
While the IOR influence can sometimes lead to "rolling" in following seas—a common trait of 1970s designs with narrower sterns—owners and reviewers in Dutch maritime circles, such as the archives of Waterkampioen, have historically praised the boat for its predictable motion and lack of "hobby-horsing" in a chop. The sail-to-displacement ratio is moderate, making it a capable cruiser-racer. In light airs, the Loper requires a generous genoa to maintain momentum, but it truly comes alive when the breeze exceeds 15 knots, where its robust construction allows the helm to remain light and responsive.
Interior Comfort & Variations
For a vessel of 27 feet, the Standfast Loper offers a functional and surprisingly offshore-capable interior layout. The cabin traditionally features a classic "V-berth" forward, followed by a compact head and a main salon with two longitudinal settees that double as sea berths. The woodwork is typical of the Standfast yard: high-quality teak or mahogany veneers that have, in many cases, survived decades without warping.
One of the Loper's defining interior traits is its "galley-aft" configuration, which places the stove and sink near the companionway for better ventilation and accessibility for the on-watch crew. Headroom is approximately 1.75 meters (5'9"), which is generous for the era but may feel restrictive for taller sailors. While the Loper did not have the sheer number of variations seen in larger models like the Standfast 40, some units were customized with different cabinet configurations or navigations stations, depending on whether the original owner prioritized racing or coastal cruising.
Known Issues & Buyer’s Checklist
Prospective buyers of a Standfast Loper should focus their inspections on several high-signal areas common to Dutch yachts of this vintage:
- Engine Service Life: Many Lopers were originally fitted with Farymann or Bukh diesel engines. While reliable, these units are now approaching the end of their service life, and parts availability can be a challenge. Buyers should check for recent repowers (e.g., Yanmar or Beta).
- Deck Core Integrity: Standfast utilized a sandwich construction for the decks to save weight. Over time, moisture can ingress through hardware fittings (stanchions, cleats, or winches), leading to delamination or soft spots in the balsa core.
- Rudder Bearings: Due to the high loads transmitted by the deep rudder, the bearings can develop play. This is often felt as a "thumping" in the tiller or steering system while underway.
- Osmosis: While Standfast hulls were heavily built, 1970s resins are susceptible to osmotic blistering. A moisture meter reading of the hull below the waterline is essential, though many Lopers have since undergone preventative epoxy treatments.
Community & Resources
The primary hub for technical data and owner history is the Standfast Club, a dedicated association for owners of Frans Maas-designed vessels. This group maintains historical records and technical wikis that provide invaluable support for restoration projects. Additionally, because the Loper was a staple of the Dutch racing and cruising circuit for decades, technical insights can often be found through the Dutch Association of Coastal Sailors (Nederlandse Vereniging van Kustzeilers), which recognizes the Loper as a capable offshore-rated vessel.
The Verdict
The Standfast Loper remains a premier choice for the sailor who values structural integrity and "big boat" handling in a sub-30-foot frame. It is a true sailor’s boat, rewarding technical skill with a solid, secure feel.
Pros:
- Exceptional build quality and use of premium materials (lead keel, high-grade joinery).
- Superior heavy-weather performance compared to modern light-displacement cruisers.
- Timeless aesthetic with classic Frans Maas lines.
Cons:
- Limited headroom for taller individuals.
- Potential for high maintenance costs related to aging original engines and deck cores.
- IOR-inspired hull can be "twitchy" when running downwind in a significant swell.
