The Laurin 28 (often referred to as the L28) stands as a quintessential example of the "Koster" tradition, a design philosophy rooted in the rugged fishing vessels of the Swedish west coast. Designed by the prolific Arvid Laurin, this 28-foot double-ender transitioned the seaworthy characteristics of traditional wooden Kosters into the era of fiberglass production. Primarily built by Norrlandskustens Båtbyggeri starting in the late 1960s, the L28 was conceived as a "pocket blue-water cruiser," prioritizing ultimate stability and structural integrity over light-air speed. Its hallmark is the canoe stern and a long, integrated keel that provides a level of directional stability rarely found in modern fin-keel designs.

Sailing Performance & Handling
The sailing characteristics of the Laurin 28 are defined by its high displacement-to-length ratio and its substantial ballast ratio, which often nears 45%. This creates a stiff, dry ride in heavy weather. According to historical technical summaries from the Swedish Cruising Association (Svenska Kryssarklubben), the L28 is renowned for its ability to track straight in a following sea, a direct benefit of its balanced koster stern which prevents the "wagging" motion common in wide-transom yachts.
While the boat excels in a blow, its heavy-displacement nature means it can be sluggish in light air (under 8 knots). It requires a significant amount of canvas to get moving, and owners often supplement the sail plan with a large genoa or a cruising chute. The helm is typically heavy but provides immense feedback; it is a boat that "finds its groove" and stays there. Because of the long keel, backing the L28 under power is famously difficult, often requiring the skipper to account for a significant "prop walk" before the rudder gains any bite.
Interior Comfort & Variations
For a 28-foot vessel, the L28 offers a surprisingly secure and functional interior, though it is constrained by the narrow beam inherent to the Koster design. The layout is traditional: a small galley and navigation station flanking the companionway, followed by two settee berths in the main saloon, and a V-berth in the bow. The use of high-quality Scandinavian joinery—typically mahogany or teak—gives the cabin a warm, maritime feel that has aged better than many of its contemporaries.
There are two primary deck configurations: the "Flush Deck" version and the "Doghouse" version. The flush deck variant offers a sleeker, more aesthetic profile and a massive foredeck for sail handling but sacrifices significant headroom and interior volume. The doghouse version provides a more protected entryway and increased standing headroom (approximately 1.8 meters) near the galley. Sibling models, such as the larger Laurin 32 and the rarer Laurin 38, utilize the same double-ended hull form but scale up the interior to accommodate dedicated chart tables and separate heads compartments.
Popular Mentions & Media
The Laurin 28 has earned a reputation in the "small boat, big ocean" community. Its cultural footprint is most significant in Scandinavia, where it is often cited as the entry-level vessel for aspiring circumnavigators. While it hasn't achieved the same mainstream Hollywood fame as some offshore brands, it is a staple in Swedish sailing literature as the ultimate "sea-kindly" cruiser for the Baltic and North Seas.
Known Issues & Buyer’s Checklist
Prospective buyers should approach a Laurin 28 with a focus on its structural age, as many units are now over 50 years old.
- Deck Core Delamination: Like many early fiberglass boats, the L28 used a sandwich construction for the decks (often balsa or plywood). Check for "spongy" spots around the chainplates and stanchion bases, which indicate water ingress.
- Original Engine Reliability: Many L28s were originally fitted with Volvo Penta MD7A or MD2B engines. These raw-water-cooled units are prone to internal scaling and many have reached the end of their service life. A repowered unit with fresh-water cooling is a significant value-add.
- Rudder Hardware: The rudder is hung on the trailing edge of the keel. Inspect the bronze or stainless steel pintles and gudgeons for play. If the bushings are worn, the boat will exhibit a distracting vibration or "thump" when sailing at speed.
- Chainplate Corrosion: The chainplates are bolted through the hull/deck joint. Over decades, slow leaks here can cause unseen corrosion on the bolts. It is recommended to pull at least one bolt for inspection.
Community & Resources
The most authoritative resource for this model is the Laurinkosterföreningen (The Laurin Koster Association), based in Sweden. This organization maintains technical archives, sail plans, and a register of hulls. While much of their documentation is in Swedish, they remain the primary source for verifying hull numbers and original build specifications for the L28 and its siblings.
The Verdict
The Laurin 28 is not a boat for the casual weekend racer or someone seeking a spacious "condo-on-the-water." It is a purposeful, rugged tool designed for sailors who value safety and seaworthiness above all else.
Pros
- Exceptional heavy-weather performance and sea-kindliness.
- Timeless, beautiful double-ended "Koster" aesthetics.
- Robust construction capable of offshore passages.
- Highly stable and predictable tracking.
Cons
- Poor maneuverability in reverse under power.
- Sluggish performance in light wind conditions.
- Limited interior volume compared to modern 28-footers.
- Potential for high maintenance on aging original engines and deck cores.
